Area 2 of somatosensory cortex represents kinematic details of the entire arm during movement, but this mapping from limb state to neural activity differs for reaching and passive limb displacement.
The ability to smoothly perceive the environment across saccades without disturbing retinal motion sensations is generated by eye movement contingent habituation.

fMRI results show that despite arm amputation, and varying degrees of phantom sensations, canonical hand representation in primary somatosensory cortex is largely maintained.
Neurons in motor cortex contain information about each arm, but these signals are separated into different dimensions, allowing separate control of each arm.
In vivo recordings in unanesthetized zebrafish larvae show that Purkinje neurons have two stable membrane potential states and that climbing fiber inputs can toggle them to up states during motor episodes.
A neural gating mechanism in the external cuneate nucleus of the rat brain is engaged during wake movements and disengaged during sleep-related twitches.
Activity in cortico-basal ganglia circuits of juvenile songbirds reflects evaluative signals necessary for comparing self-generated behavior to a goal representation during skill learning.
The formation and refinement of prediction error circuits relies on an experience-dependent balance of excitation and inhibition in canonical microcircuits.
Perception is proposed to be a dynamic motor-sensory closed-loop process in which information flows through the environment and the brain in continuous loops, converging towards steady-state percepts.
