Medial Geniculate Body (MGB) is the sensory relay of auditory inputs to primary regions of the auditory cerebral cortex.

• Medial Geniculate Body (MGB) is the sensory relay of auditory inputs to primary regions of the auditory cerebral cortex.

• The MGB is just lateral to the dorsal thalamus that we typically view as gating.
• Otic Radiations are efferent axons of geniculate body neurons that are the cortical projection to the primary auditory cortex as Heschl’s Gyrus.
• Like vision, sound is interlaced from two sides of body space.
