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
  • Brain area: Neocortical Brain - Sensory Aggregation Area
  • Role: thalamic.sensory.primary
  • Function: Detection of the relative intensity and duration of a sound, relay to Auditory Cortex
  • Notes to function: Thalamus
