Periaqueductal Gray Matter
@@Home -> BiologicalLifeResearch -> BrainAreaLMC -> BrainRegionLMC_MM_PAG
This page covers biological details of component Periaqueductal Gray Matter. Region is part of aHuman target integrated biological model.
- Top-down path to region: Midbrain Mesencephalon -> Periaqueductal Gray Matter (LMC.MM.PAG) (see Mind Maps)
- Type: nucleus
- Brain area: Lower Brain - Modulatory Contol Area
- Role: processor.autonomic
- Function: Descending modulation of pain and in defensive behaviour
- Notes to function:
- if there is a lesion in the PAG, then consciousness is lost
- electrical stimulation of the PAG results in immediate and profound analgesia
- modulatory nucleus
