----

This page covers biological details of component Broca's Area Pars Triangularis.
Region is part of aHuman target integrated biological model.

  * *Top-down path to region*: Cerebral Cortex -> Anterior Lobe (NC.LOBE.ANT) -> Prefrontal Cortex (NC.AL.PFC) -> [BrainCenterNC_AL_LPFC Lateral Prefrontal Cortex] (NC.AL.LPFC) -> Ventrolateral Prefrontal Cortex (NC.AL.VLPFC) -> Broca's Area (NPE.NC.PFC.BRA) -> [BrainRegionNPE_NC_BRA_PT Broca's Area Pars Triangularis] (NPE.NC.BRA.PT) (see [OverallMindMaps Mind Maps])
  * *Type*: cortex
  * *Quality*: L0
  * *Brain area*: [BrainAreaNPE Neocortical Brain - Unimodal Execution Area] (NPE)
  * *Area circuit*: Execution by Auditory Inputs (AES)
  * *Brodmann ID*: 45
  * *Role*: cortex.generic
  * *Function*: Language production and prefrontal associational integration, propositional language comprehension
  * *Notes to function*: 
   * Triangular Inferior Frontal Gyrus, switching between semantic sub-categories in word retrieval
