(also geniculate nucleus)
Either of two protuberances on the inferior surface of the thalamus that relay auditory and visual impulses respectively to the cerebral cortex.
- At the rear end of the thalamus are the smaller medial and lateral geniculate nuclei, relaying auditory and visual pathways, respectively, to the auditory and visual areas of the cortex.
- Neurons from the lateral geniculate nucleus then send axons to the visual cortex.
- The ventral notch in the lateral geniculate body was filled with optic tract fibers and these have been removed to show the nucleus.
