Which of the following nuclei acts as the primary relay station in the thalamus for auditory signals before they reach the primary auditory cortex?
- A.Ventral posterolateral nucleus (VPL)
- B.Lateral geniculate nucleus (LGN)
- C.Medial geniculate nucleus (MGN)Correct answer
- D.Ventral anterior nucleus (VA)
Solution
The medial geniculate nucleus (MGN) of the thalamus relays auditory information from the inferior colliculus to the primary auditory cortex (transverse temporal gyri of Heschl). The LGN is for vision, and the VPL is for somatosensory pathways.
