@@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
- Quality: L0
- Brain area: Neocortical Brain - Motor Aggregation Area (NMA)
- Area circuit: Complex Motor (SEQ)
- 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
