This study in budding yeast (S. cerevisiae) presents important findings demonstrating that the exonuclease Xrn1 regulates autophagy in response to methionine deprivation through effects on TORC1. There is solid evidence that the impact of Xrn1 on TORC1 is contingent on its catalytic activity rather than the degradation of any specific category of mRNAs. A major strength is the novel mechanism, in which Xrn1 modulates the nucleotide-binding state of the Gtr1/2 complex.

eLife assessment

This potentially important study examines patterns of diversity and divergence in two closely related sub-species of Zea mays, patterns that have bearings on local adaptation in maize and teosinte at intermediate geographic scales. The authors suggest that convergent evolution has been facilitated by both standing variation and gene flow, with independent selective sweeps in the two species. Limitations concerning population sampling, false positive rates in sweep detection and integration of phenotypic data at this stage only inadequately support the major conclusions. The work should in principle be of broad interest to colleagues studying the relationship between domesticated species and their progenitors, as well as those studying instances of parallel evolution.

eLife assessment

This work provides a valuable contribution and assessment of what it means to replicate a null study finding, and what are the appropriate methods for doing so (apart from a rote p-value assessment). Through a convincing re-analysis of results from the Reproducibility Project: Cancer Biology using frequentist equivalence testing and Bayes factors, the authors demonstrate that even when reducing 'replicability success' to a single criterion, how precisely replication is measured may yield differing results. Less focus is directed to appropriate replication of non-null findings.

This important study assesses anatomical, behavioral, physiological, and neurochemical effects of early-life seizures in rats, describing a striking astrogliosis and deficits in cognition and electrophysiological parameters. The convincing aspects of the paper are the wide range of convergent techniques used to understand the effects of early-life seizures on behavior as well as hippocampal prefrontal cortical dynamics. While reviewers thought that the scope was impressive, there was criticism of the statistical robustness and number of animals used per study arm, as well as the lack of causal manipulations to determine cause-and-effect relationships. This paper will be of interest to neurobiologists, epileptologists, and behavioral scientists.

This manuscript makes a valuable contribution to understanding the entanglement of homeostatic structural plasticity and synaptic scaling, yet only homeostasis after activity deprivation is studied in depth. The experimental and computational methods are solid but overall incomplete as the link between them remains qualitative. The conclusions drawn from the results are rather vague and their generality or relevance for other research fields is not made clear.

eLife assessment

This manuscript addresses infections of the parasite Taenia solium, which causes neurocysticercosis (NCC). NCC is a common parasitic infection that leads to severe neurological problems. It is a major cause of epilepsy, but little is known about how the infection causes epilepsy. The authors used neuronal recordings, imaging of calcium transients in neurons, and glutamate-sensing fluorescent reporters. A strength of the paper is the use of both rodent and human preparations. The results provide convincing evidence that the larvae secrete glutamate and this depolarizes neurons. Although it is still uncertain exactly how epilepsy is triggered, the results suggest that glutamate release contributes. Therefore, the paper is an important initial step towards understanding how Taenia solium infection leads to epilepsy.

eLife assessment

In this valuable manuscript Li & Jin record from the substantial nigra and dorsal striatum to identify subpopulations of neurons with activity that reflects different dynamics during action selection, and then use optogenetics in transgenic mice to selectively inhibit or excite D1- and D2- expressing spiny projection neurons in the striatum, demonstrating a causal role for each in action selection in an opposing manner. They provide solid evidence for the argument that their findings cannot be explained by current models and propose a new 'triple control' model instead, with one direct and two indirect pathways, although direct evidence for a second indirect pathway is still lacking. These findings will be of broad interest to neuroscientists across multiple subfields.

eLife assessment

This study provides a comprehensive whole genome transcriptomic analysis of three small mammals, including Peromyscus leucopus, after exposure to endotoxin lipopolysaccharide.

This work will be of broad interest to cell biologists who wish to determine limiting factors in gene regulatory networks.

eLife assessment

This work presents valuable new information on the microtubule-binding mode of the microtubule kinesin-13, MCAK. The authors use quantitative single-molecule studies to propose that MCAK preferentially binds to a GDP-Pi-tubulin portion of the microtubule end. However, the evidence provided to support this claim remains incomplete and would benefit from a more rigorous methodology. Additionally, the physiological relevance of the proposed binding mode remains speculative.

The work will be of broad interest to microbiologists and biochemists.

eLife assessment

This study is valuable and contains results that are supported by convincing evidence. In the future, the observations could be further strengthened by independent validation, and by looking at larger numbers of patients, as well as by determining whether patient heterogeneity is either contributing to or obscuring certain patterns.

eLife assessment

The intrinsic chirality of actin filaments (F-actin) is implicated in the chiral arrangement and movement of cellular structures, but it was unknown how opposite chiralities can arise when the chirality of F-actin is invariant. Kwong et al. present evidence that two actin filament-based cytoskeletal structures, transverse actin arcs and radial stress fibers, drive clockwise and anti-clockwise rotation, respectively. This fundamental work, which has broad implications for cell biology, is supported by solid data, although the effect of the perturbations should be interpreted with caution.

This study makes a valuable contribution by characterizing the role of the exocyst in secretory granule exocytosis in the Drosophila larval salivary gland. The results lead to the novel interpretation that the exocyst participates not only in exocytosis, but also in earlier steps of secretory granule biogenesis and maturation. Although these ideas are potentially of interest to a wide range of membrane traffic researchers, the evidence is incomplete, and the authors are urged to consider the possibility that inactivation of an essential exocytosis component might have indirect effects on other parts of the secretory pathway.

Overall, this research highlights the role of human movements in maintaining residual malaria transmission in an area targeted for intensive control interventions over the past decades and provides valuable information for epidemiologists and public health professionals.

eLife assessment

This important study combines laboratory and field studies to quantify the force of human malaria parasite transmission. The methods of malaria parasite quantification in the mosquito midgut and salivary glands are compelling, but the statistical analyses seem to be biased by high infection loads of laboratory infections and would benefit from a more granular assessment of low parasite loads observed in the field. The study establishes a correlation between the sporozoite loads in the mosquito and the number of expelled parasites and would be of interest to vector biologists, parasitologists, immunologists, and mathematical modellers.

This valuable manuscript attempts to identify the brain regions and cell types involved in habituation to dark flash stimuli in larval zebrafish. Habituation being a form of learning widespread in the animal kingdom, the investigation of neural mechanisms underlying it is a worthwhile endeavor. The authors use a combination of behavioral analysis, neural activity imaging, and pharmacological manipulation to investigate brain-wide mechanisms of habituation. While the data presented are solid, the authors conclude that there is no simple relationship between pharmacological intervention, neural activity patterns, and behavioral outcomes, and a robust causative link can therefore not be established.

Yang et al. investigate whether distinct sources of conflict are represented in a common cognitive space. The study uses an interesting task that mixes different sources of difficulty and reports that the brain appears to represent these sources as a mixture on a continuum in prefrontal areas. While the findings could be valuable to theory in this area, there are concerns with the analysis, design and results, that raise uncertainty regarding the main conclusion of a shared cognitive space. Thus, the evidence reported here remains incomplete.

eLife assessment

This is valuable study on the mechanistic relationship between two prominent events in post-stimulus EEG: alpha desynchronization and P300 that are known for their slow/relatively late build up. The sample size is substantial. The data are compelling, showing that the P300 can be explained by desynchronization of a non-zero mean alpha oscillations over posterior sites through the baseline-shift model, at least partially. This makes a significant contribution to understanding and interpreting P300 generation (and possibly other ERP components) from concurrent changes in brain oscillations, with links to cognition.

eLife assessment

This valuable work proposes a framework inspired by chemotaxis for understanding how the brain might implement behaviours related to navigating toward a goal.

This important paper provides solid evidence that the angular gyrus plays a role in insight-based memory updating. The study is well conducted, timely, and presents clear-cut behavioral results. Analyses of the EEG data leave open questions, and evidence for the strong claim of a causal contribution of the angular gyrus in particular - apart from other connected regions, including the hippocampus - is not conclusive.

eLife assessment

The authors performed a useful RNAi screen to identify epigenetic regulators involved in oxygen-glucose deprivation (OGD)-induced neuronal injury. PRMT5 was identified as a negative regulator of neuronal cell survival after OGD. Solid in vitro and in vivo data suggest that PRMT5 could be a novel therapeutic target for the treatment of ischemic stroke.

eLife assessment

The finding that Fusicoccin (FC-A) promotes locomotor recovery after spinal cord injury is useful, and the idea of harnessing small molecules that may affect protein-protein interactions to promote axon regeneration is interesting and worthy of study. However, the main methods, data, and analyses are inadequate to support the primary claim of the manuscript that a 14-3-3-Spastin complex is necessary for the observed FC-A effects.

eLife assessment

This valuable study extends the previous interesting work of this group to address the potentially differential control of movement and posture. Through experiments in which stroke participants used a robotic manipulandum, the authors provide evidence supporting a lack of a relation between the resting force postural bias they measure (closely related to the flexor synergy in stroke) and kinematic deficits during movement. Based on these results, the authors propose a conceptual framework that differentially weights the two main descending pathways (corticospinal tract and reticulospinal tract) for neurologically intact and stroke patients. The reviewers point out that some of the evidence supporting the authors' conclusions is incomplete, and that the study would benefit from considering alternative explanations involving other mechanisms, which could be addressed with additional experiments and analyses.

eLife assessment

This important paper sheds light on the role of expectations in perceptual decision-making. Sophisticated analyses of human EEG data provide convincing evidence that both motor preparation and sensory processing were affected by expectations, albeit with different time courses. These findings will be of interest to scientists interested in perception and decision-making.

eLife assessment

Peripheral neurons are capable of regeneration after injury, however it is not known if all of these neurons react in the same way. The results presented here are useful to the field and strongly indicate with solid evidence that different classes of neurons exhibit different speeds of regeneration. The reason for these key differences is explored by the finding of potential factors and genes that contribute to the regulation of regenerative capacity.

This comprehensive study presents valuable results that delineate the involvement of a small subset of (DL1) dopaminergic neurons in the Drosophila larva's aversive learning response to high salt. Systematic loss-of-functional and gain-of-function manipulations coupled with in-vivo calcium imaging offer compelling evidence for the pivotal roles of these neurons, thereby advancing our understanding of the cellular mechanisms underlying associative conditioning. Despite its report of notable similarities between the learning mechanisms of learning in flies and mammals, the work underscores the necessity to further elucidate the interplay between aversive and appetitive pathways in future work.

eLife assessment

This important work combines molecular genetics and behavioral analyses to identify neurons in the female mouse preoptic area that respond specifically to mating completion. These experiments are rigorous and well-performed. The data convincingly demonstrate a subpopulation of neurons in the medial preoptic area that are selectively activated following the completion of mating in females. But concerns around the timing of the labeling of neurons as being specific to mating completion make the some conclusions incomplete, in the manuscript's current form. Confounds around the mating satiety status of the male partners influencing the motivation of the females also result in a study that is not complete.

eLife assessment

This important study presents evidence to support the efficacy of oral administration of DNL343, an integrated stress response (ISR) suppressor, in two mouse models in which neurodegeneration is induced. This suggests a therapeutic potential for ISR-related neurodegenerative diseases based on DNL343. The results from the in vivo animal models are convincing. However, adequate analyses are needed to fully support the conclusion, as there is no evidence that DNL343 acts in vitro.

The findings of this article provide valuable information on the changes of cell clusters induced by chronic periodontitis. The observation of a new fibroblast subpopulation, named AG fibroblasts, is interesting, and the strength of evidence presented is solid.

eLife assessment

This is a valuable comparative study of adaptation across multiple species. The results provide a solid example of the application of genotype-environment associations to demonstrate that local adaptation is repeatable.

eLife assessment

Multimodal experiences that for example contain both visual and tactile components are encoded as associative memories. This manuscript is a valuable contribution supporting structural and functional brain plasticity following associative training protocols that pair together different types of sensory stimuli. The results provide solid support for this plasticity being a basis for cross-modal associative memories.

This valuable paper presents a new protocol for quantifying tRNA aminoacylation levels by deep sequencing. The improved methods for discrimination of aminoacyl-tRNAs from non-acylated tRNAs, more efficient splint-assisted ligation to modify the tRNAs' ends for the following RT-PCR reaction, and the use of an error-tolerating mapping algorithm to map the tRNA sequencing reads provide new tools for anyone interested in tRNA concentrations and functional states in different cells and organisms. The results and conclusions are solid with well-designed tests to optimize the protocol under different conditions.

eLife assessment

This valuable study reports on the potential of neural networks to emulate simulations of human ventricular cardiomyocyte action potentials for various ion channel parameters with the advantage of saving simulation time in certain conditions. The evidence supporting the claims of the authors is solid, although the inclusion of open analysis of drop-off accuracy and validation of the neural network emulators against experimental data would have strengthened the study. The work will be of interest to scientists working in cardiac simulation and quantitative pharmacology.

eLife assessment

This is an important study highlighting a distinct role of WASP dependent actin foci in B cell antigen receptor signalling. The evidence supporting the conclusions is compelling. The proposal of higher molecular density in B cell receptor clustering leading to kinase exclusion and attenuated signalling is provocative as it contrasts with models for other antigen receptors.

eLife assessment

O'Brien and co-authors addressed how statins reduce levels of aldosterone in humans and provide important data demonstrating that tissue-resident macrophages can exert physiological functions and influence endocrine systems. However, the strength of evidence, as of now, is incomplete, as the sole description of the phenotype of MARCO-deficient mice is insufficient to claim that MARCO in alveolar macrophages can negatively regulate ACE expression and aldosterone production at steady-state. The work will be of broad interest to cell biologists and immunologists.

eLife assessment

This study presents a useful inventory of the joint effects of genetic and environmental factors on psychotic-like experiences and identifies cognitive ability as a potential underlying mediating pathway. The data were analyzed using a solid and validated methodology based on a large, multi-center dataset. The claim that these findings are of relevance to psychosis risk and have implications for policy changes is partially supported by the results.

eLife assessment

This study presents a valuable finding on relationship between high protein diet and resistance exercise on fat accumulation and glucose homeostasis. The evidence supporting the claims of the authors is solid, although inclusion of mechanistic insight would have strengthened the study. The work will be of interest to dietician and exercise biologists working to understand the synergy between diet and physical activity.

eLife assessment

This study reports a new approach to determine the architecture of peptidoglycan (PG), the primary component of the bacterial cell wall, validating the pipeline through an architectural analysis of several members of the human gut microbiota. The technique is potentially valuable for this sub-field as it would enable researchers interested in peptidoglycan in a range of organisms to easily assess muropeptide composition in an easy, automated manner. However, there is some uncertainty about whether the pipeline was fully automated and it was noted that the pipeline requires prior knowledge of the peptidoglycan composition of an organism. Additionally, the use of the technique to investigate whether PG cross-bridge length is a determinant of cell wall stiffness produced evidence that would need more direct support and is therefore so far incomplete.

eLife assessment

This manuscript reports important findings, demonstrating a critical role for a cysteine-containing dimerization interface in the secretion of FGF2 through an unconventional pathway. The authors provide compelling evidence, combining in vitro biochemical assays with structural simulation. The work will be of interest to researchers working on protein trafficking and secretion.

eLife assessment

This important study describes the coordinated regulation of cellular size and protein translation in response to chronic stress as an adaptive mechanism, termed the 'rewiring stress response' regulated by the heat shock response. The evidence supporting this conclusion is solid, utilizing diverse methods to monitor and manipulate cell size and evaluate stress resistance. The study could be strengthened by the inclusion of more experiments focused on defining the mechanistic basis of this coordination and broadening the scope of the specific role of the 'rewiring stress response' across different chronic cellular stresses. This work will be of broad interest to researchers interested in diverse fields including cellular proteostasis, stress-responsive signaling, and aging and senescence.

eLife assessment

This is an important contribution to the origins and translational consequences of the relatively low rate of translation elongation in the first ∼30-50 codons of genes in most organisms. The authors provide convincing evidence that the prevalence of rare codons in the first ~40 codons in yeast is due to the relatively recent evolution of these coding sequences, or of lower purifying selection operating on them, and that a preponderance of codons encoded by rare tRNAs near the N-terminus is not associated with higher translational efficiency in the manner proposed by the "translational ramp" hypothesis. The work is incomplete in that the results of reporter assays may have been confounded by alterations of mRNA sequence or structure that could have influenced their translation or mRNA stability; that the work cannot fully account for a greater enrichment of slowly translated codons in N-terminal vs. C-terminal regions; and that the work does not resolve whether translation elongation through N-terminal coding is truly slow.

eLife assessment

This manuscript provides important insights into the degradation of a host tRNA modification enzyme TRMT1 by SARS-CoV-2 protease nsp5. The data convincingly support the main conclusions of the paper. These results will be of interest to virologists interested in studying the alterations in tRNA modifications, host methyltransferases, and viral infections.

eLife assessment

This study reports biochemical and structural analysis of two PLP decarboxylase enzymes from plants. The findings are useful due to the utility of these enzymes in industrial theanine production. While certain aspects of the study are solid, other components elucidating the role of a Zn(II)-binding motif are incomplete. In addition, some of the finding could be presented more clearly, including the connections between the structural findings and the reaction mechanism. The work will be of interest to enzymologists studying PLP enzymes and those interested in enzyme engineering in plants.

eLife assessment

This manuscript provides important structural insights into the recognition and degradation of the host tRNA methyltransferase by SARS-CoV-2 protease nsp5 (Mpro). The data convincingly support the main conclusions of the paper. These results will be of interest to researchers studying structures and substrate recognition and specificity of viral proteases.

eLife assessment

This comprehensive study provides valuable information on the cooperation of Ikaros with Foxp3 to establish and regulate a major portion of the epigenome and transcriptome of T-regulatory cells. However, the characterization is incomplete in that incontrovertible evidence that these are intrinsic features regulating biological function and not outcomes of the inflammatory micro-environment of the genetically manipulated mice is missing.

eLife assessment

This valuable study advances our understanding of the relationship between different mammalian ligands and receptors of the Notch signaling pathway. The authors systematically evaluate the effects of different combinations of ligands and receptors on levels of pathway activation. The convincing though not always complete data uncover interesting and unexpected differences, which provide a foundation for interpreting Notch signaling events in normal and disease contexts where this pathway operates.

eLife assessment

In this valuable study the authors propose a new regulatory role for one the most abundant circRNAs, circHIPK3, mediated by the RNA binding protein IGF2BP2. While the study presents interesting and largely solid evidence, part of the work is incomplete, requiring additional controls to more robustly support the major claims. The work would also benefit from further discussion addressing the apparently contradictory effects of circHIPK3 and STAT3 depletion in cancer progression.

eLife assessment

This is an important study describing the function of Laminin γ1-dependent basement membranes in the development of the olfactory placode, including morphogenesis of the placode, boundary formation, and olfactory axonal pathfinding. The study uses elegant live imaging approaches, and detailed mutant analyses to provide a convincing description of the role of Laminin in olfactory placode development, although the mechanisms by which Laminin γ1 regulates these processes are not conclusive. In addition to the contributions this study makes to understanding olfactory placode development, it will also be of broader interest to individuals interested in extracellular matrix regulation of tissue morphogenesis, and neural development including neuronal pathfinding.

eLife assessment

In a valuable study that will be of interest to the mechanistic membrane transport community, the authors capture the first cryo-EM structure of the inward facing melbiose transporter MelB, a well-studied model transporter from the major facilitator (MFS) superfamily. Cryo-EM experiments and supporting biophysical experiments provide solid evidence for transporter conformational changes. The supporting evidence is incomplete in that the maps were not provided for review.

eLife assessment

This important study convincingly shows that the less common D-serine stereoisomer is transported in the kidney by the neutral amino acid transporter ASCT2 and that it is a non-canonical substrate for sodium-coupled monocarboxylate transporter SMCTs. With a multi-hierarchical approach, this important study further shows that Ischemia-Reperfusion Injury in the kidney causes a specific increment in renal reabsorption carried out, in part, by ASCT2.

eLife assessment

This is a useful study that investigates neural circuits mediating behavioral responses to cold in Drosophila larvae. Using a combination of behavioral analysis, neuronal manipulation, EM connectomics, and reporters of calcium activity, the authors convincingly show that cold-induced body contraction is mediated by specific central neurons. However, the strength of evidence is incomplete due to the concern that larval contraction is a result of chilling the nervous system and muscles, which causes spreading depolarization and mechanical contraction of the body, rather than an active sensorimotor response to cold. With these concerns addressed, this paper would be of interest to neuroscientists interested in temperature sensing.

eLife assessment

Antibodies are some of the most critical tools in biomedical research. However, their quality and specificity vary significantly. This fundamental study provides guidelines for how the quality of an antibody should be assessed and recorded and provides compelling data on the selected antibodies. This paper will be of interest to researchers working in experimental cell biology.

eLife assessment

This is an important study on how behavioral context affects decision making in the nematode C. elegans. Behavioral analyses at multiple time scales combined with genetic and neuronal manipulations revealed how arousal states affect decision making. The results and interpretations are convincing. This work will be of interest to both neuroscientists and ecologists.

eLife assessment

In this valuable study, the authors characterize the role of splicing factor SRSF1 during spermatogenesis with a conditional knockout for Srsf1 in male mouse germ cells. The requirement of SRSF1 for maturation of postnatal gonocytes into spermatogonia, and the molecular role of SRSF1 in regulating alternative splicing in juvenile testes are convincingly supported. The paper also provides strong evidence that the mRNA encoding Tial, a factor relevant for spermatogonial maintenance and male fertility, is alternatively spliced in testis and that this splicing is regulated by SRSF1. The work will be of interest to reproductive biologists and stem cell biologists.

eLife assessment

This valuable study provides extensive high-quality imaging data and new insights into the process of the endothelial-to-hematopoietic transition (EHT), which generates nascent hematopoietic stem cells from the ventral wall of the dorsal aorta. This study provides strong evidence that, based on apicobasal cell polarity, different morphologies exist for emergent hematopoietic stem cells. The study is incomplete at present in that it does not yet support the additional claim that there are functional consequences, as altered cell fate related to these different morphologies has not been definitively shown.

eLife assessment

Studies of synaptic development and plasticity in the nematode C. elegans have been limited by the difficulty of rapid, accurate assessments of synaptic structure. In this valuable work, the authors convincingly introduce and validate a computational pipeline, "WormPsyQi," that allows rapid, reproducible quantitation of fluorescent synaptic puncta while minimizing human error and bias. The authors also describe a new set of strains carrying synaptic markers. Together, these tools should provide many groups studying this model system with the ability to quantitatively characterize chemical and electrical synapses, even in densely packed regions in 3D space such as the nerve ring.

eLife assessment

Using the continuum theory of elastic solids, the authors suggest that periodic muscle contraction leads to elongation of C. elegans embryos by storing elastic energy that is subsequently released by extending the embryo's long axis. This important finding could apply to other developmental processes and be exploited in soft robotics. While the presented evidence is in principle convincing, features of the the theory are not explained in sufficient detail.

eLife assessment

This is an important demonstration of how the false-positive rate of high-resolution 2D template matching to find particles of a given target structure in 2D cryo-EM images (2DTM) relates to overfitting the data towards the template. The authors present new methods to measure the amount of model bias that gets introduced in high-resolution features of such maps, with compelling evidence that high-resolution features that are not present in the template can still be reconstructed in 3D from images obtained by 2DTM.

eLife assessment

This study presents a useful new approach for efficient computation of statistics on correlations between genetic variants (linkage disequilibrium, or LD), which the authors apply to quantify the extent of LD across chromosomes. The method and its derivation are solid. The authors document that cross-chromosome LD can be substantial, which has implications for geneticists who are interested in population structure and its impact on genetic association studies.

eLife assessment

This important proof-of-concept study strongly supports the utility of functional ultrasound imaging for evaluating cerebral hemodynamics in rat models of brain injury. Functional ultrasound affords a distinct coverage/spatial/temporal resolution tradeoff when compared to other modalities for studying brain hemodynamics. The solid data presented indicate high fidelity of the recordings, a particular feat given that the rats were awake. On the other hand, single slice imaging and complexity of registration of subsequent imaging sessions limit the usefulness of the approach, particularly for quantitative imaging, and the small sample size will need to be followed up with and verified by future studies. This work will be of interest to researchers working in functional neuroimaging and more precisely with preclinical models of stroke in rodents.

eLife assessment

This important study shows that pharmacologically enhanced catecholamine levels and increased voluntary spatial attention have overlapping as well as dissociable effects on performance on a visuospatial attention task and corresponding EEG markers. The findings provide solid evidence regarding how neuromodulatory arousal and selective spatial attention jointly shape perceptional decision-making.

eLife assessment

This study presents valuable findings about synaptic connectivity among subsets of unipolar brush cells (UBCs), a specialized interneuron primarily located in the vestibular lobules of the cerebellar cortex. The evidence supporting the claims are interesting although incomplete in some areas. The work will be of interest to cerebellar neuroscientists as well as those focussed on synaptic properties and mechanisms. Although several compelling pieces of data were presented, substantial work remains to be conducted in order for the hypothesis and predictions of the manuscript to confirm how these factors play out in the actual brain circuit and how it would impact the processing of feedback or feedforward activity that would be required to promote behavior.
