Supplementary Motor Cortex
@@Home -> BiologicalLifeResearch -> BrainCenterNMA_NC_SMC
This page covers biological details of component group Supplementary Motor Cortex. Component group is part of aHuman target integrated biological model.
- Top-down path to center: Cerebral Cortex -> Anterior Lobe (NC.LOBE.ANT) -> Supplementary Motor Cortex (NMA.NC.SMC) (see Mind Maps)
- Function: Process sequences of movements and coordinate bilateral movements
