(redirected from Nucleus dorsalis)

medial geniculate nuclei

nerve cells that collectively form a surface elevation, the medial geniculate body; they comprise a ventral principal nucleus [TA], a dorsal nucleus [TA], and a small medial magnocellular nucleus; the cells play a role in the relay of auditory input to the auditory cortex.

Two of the main lemnothalamic pathways are shown from the dorsal column nuclei to the nucleus dorsalis intermedius ventralis anterior (DIVA) and from retinal ganglion cells directly to the dorsal lateral geniculate nucleus (DLGN), a nucleus previously referred to in birds as the nucleus opticus principalis thalami, or OPT.
