Supplementary Motor Area

@@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*: 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*: processor
• *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
