Summary:[...]rather than being linear in its layout, the monkey motor cortex has a concentric organization (for example, the hand region is flanked on both sides by regions controlling the wrist, elbow and shoulder)6,7. [...]some motor-cortex subregions participate in decidedly non-motor actions - the regulation of arousal signals for fight-or-flight behaviours8, for instance. [...]it is worth noting that a human electrophysiological study published on the preprint server bioRxiv10 has described an area embedded in the motor cortex where neural responses to body movements resemble those seen in the inter-effector regions reported by Gordon and colleagues.
