This page covers biological details of component Pre-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) -> Pre-Supplementary Motor Area (NMA.NC.SMC.F6) (see Mind Maps)
  • Type: cortex
  • Brain area: Neocortical Brain - Motor Aggregation Area
  • Brodmann ID: 06
  • Role: cortex.generic
  • Function: High level motor functions; Numerical and verbal mental-operation tasks
  • Notes to function: from TH/VLpc, MD from caudate, CR; F5/24c/46; no connections with F1
