To disentangle the various measures used in different studies, we distinguish three main measures: network activation, network intra-connectivity, and network interconnectivity.

precuneus

Here, the primary regions that are focused are the posterior cingulate cortex (PCC), precuneus (PCu), and medial prefrontal cortex (mPFC) for the DMN; dorsal lateral prefrontal cortex (dlPFC) for the CEN; and the anterior cingulate cortex (ACC) and insula for the SN.

Each region in the brain has a unique spatial distribution of functional connectivity. Some regions have functional connectivity that is highly similar. We have referred to those regions as a “system” or “network.” A system in the presently used sense means a set of widely distributed brain regions that exhibit consistently correlated spontaneous activity fluctuations and characteristically respond in concert during conventional, task-related fMRI experiments.

parietal lobule one of two divisions, inferior and superior, of the parietal lobe of the brain.

When we stub-bornly continue to mean by taste a mode of attention that cuts acrossthe classification of receptors we are only recognizing the fact that re-ceptors may be functionally united when anatomically separated. Infact, the word palate, although used in anatomy to mean the back of themouth, is used in gastronomy to mean the whole complex of receptorscontributing to palatability, that is, an organ of perception.

The organs of sensitivity, like other organs of the body, exist in a hier-archy of organization. Lower organs are subordinated to higher. Smallerstructures serve larger structures, and they overlap. The eyeball is "all ofa piece," but it is an unusual sense organ. The ear, the functional auditoryorgan, is not a single piece of tissue, and the organ of touch is dispersedover the whole body. The receptive and the adjustive parts of an organneed not be in the same place. The olfactory organ that we call the nose,that is, the functional nose, has its receptive part deep in the facial bonesbut its motor part in the chest muscles for breathing and sniffing. Thereceptive and the adjustive part can only be understood in relation to oneanother.

• ORGANS. An organ of sensitivity is a structure containing many energyreceptors and many receptive units that can adjust so as to modify theinput from cells and units. An organ must therefore have muscles, andthey must be supplied with efferent fibers from the central nervous system.:rhe afferent and efferent fibers, incoming and outgoing, may be gatheredin a single bundle, a nerve, like the nerve from each eye, or they may bedistributed in many bundles, like the fibers from the skin. The so-calledsensorynerves are anatomical expedients; there is not a specific nerve foreach sense despite a popular idea to the contrary.

note that the ‘cinguloopercular’ network is also sometimes referred to as the ‘cingulo-insular’ network (Sadaghiani, et al., 2010)

Chesterton's fence (uncountable) (public policy) The principle that reforms should not be made until the reasoning behind the existing state of affairs is understood.

Statistical heterogeneity is the term given to differences in the effects of interventions and comesabout because of clinical and/or methodological differences between studies (ie it is a consequenceof clinical and/or methodological heterogeneity). Although some variation in the effects ofinterventions between studies will always exist, whether this variation is greater than what isexpected by chance alone needs to be determined.

Scaffolding is the act of providing learners with assistance or support to perform a taskbeyond their own reach if pursued independently when “unassisted.”

Schemas are chunks of multiple individual units of memory that are linked into a system ofunderstanding

Learning is defined to be “storage of automated schema in long-term memory.

What Is a Blockchain Oracle? A blockchain oracle is a secure piece of middleware that facilitates communication between blockchains and any off-chain system, including data providers, web APIs, enterprise backends, cloud providers, IoT devices, e-signatures, payment systems, other blockchains, and more. Oracles take on several key functions: Listen – monitor the blockchain network to check for any incoming user or smart contract requests for off-chain data. Extract – fetch data from one or multiple external systems such as off-chain APIs hosted on third-party web servers. Format – format data retrieved from external APIs into a blockchain readable format (input) and/or making blockchain data compatible with an external API (output). Validate – generate a cryptographic proof attesting to the performance of an oracle service using any combination of data signing, blockchain transaction signing, TLS signatures, Trusted Execution Environment (TEE) attestations, or zero-knowledge proofs. Compute – perform some type of secure off-chain computation for the smart contract, such as calculating a median from multiple oracle submissions or generating a verifiable random number for a gaming application. Broadcast – sign and broadcast a transaction on the blockchain in order to send data and any corresponding proof on-chain for consumption by the smart contract. Output (optional) –  send data to an external system upon the execution of a smart contract, such as relaying payment instructions to a traditional payment network or triggering actions from a cyber-physical system.
