@@Home -> BiologicalLifeResearch -> BrainAreaNMA -> BrainRegionNMA_NC_SMC_F3


This page covers biological details of component Supplementary Motor Area. Region is part of aHuman target integrated biological model.

  • Top-down path to region: Cerebral Cortex -> Anterior Lobe (NC.LOBE.ANT) -> Supplementary Motor Cortex (NMA.NC.SMC) -> Supplementary Motor Area (NMA.NC.SMC.F3) (see Mind Maps)
  • Type: cortex
  • Brain area: Neocortical Brain - Motor Aggregation Area
  • Brodmann ID: 06
  • Role: cortex.generic
  • Function: Movement execution; Numerical and verbal mental-operation tasks
  • Notes to function: from TH/VLo from from putamen; F1/F2/F4/24d - strong; F6/F7/F5/24c - modest; no input from the prefrontal lobe
