Medial Geniculate Body
@@Home -> BiologicalLifeResearch -> BrainAreaNSA -> BrainRegionNSA_FD_TH_MGB
This page covers biological details of component Medial Geniculate Body. Region is part of aHuman target integrated biological model.
- Top-down path to region: Forebrain Diencephalon -> Thalamus (FD.TH) -> Sensory Thalamus (FD.TH.SR) -> Medial Geniculate Body (NSA.FD.TH.MGB) (see Mind Maps)
- Type: nucleus
- Quality: L0
- Brain area: Neocortical Brain - Sensory Aggregation Area (NSA)
- Area circuit: Neocortical Audition Aggregation (NAA)
- Role: thalamic.sensory.primary
- Function: Detection of the relative intensity and duration of a sound, relay to Auditory Cortex
- Notes to function:
- Thalamus
