Using chemogenetic manipulation, the authors induce or suppress activity in D1 spiny neurons in the dorsomedial striatum of mice. The results effectively demonstrate that excitation or inhibition of this class of neurons results in a consistent behavioral effect that is linked to an impact on local dynamics in thalamic regions that project to this part of the thalamus, as well as cortical regions that can be more readily defined as unimodal as identified by a classification approach. This work has clear relevance to the field of neuroimaging, getting at the broader hemodynamic signatures of direct pathway stimulation in the striatum, but requires critical revisions to justify their main conclusions.
