dorsal nucleus of thalamus

(redirected from lateral dorsal nucleus)

dorsal nu·cle·us of thal·a·mus

one of the major subdivisions of the thalamus; the composite dorsal nucleus includes the nucleus lateralis anterior or dorsalis, nucleus lateralis intermedius, nucleus lateralis posterior, and pulvinar; together, these cell groups form most of the free dorsal surface of the posterior half of the thalamus and project to a very large region of parietal, occipitoparietal, and temporal cortex; its afferent connections are largely obscure, but the nucleus lateralis posterior and the pulvinar receive a projection from the superior colliculus.

For the anterior part of MD, which is initially situated just caudal and ventral to the anterior ventral nucleus; lateral to the lateral dorsal nucleus; the internal medullar lamina (IML) spreads ventrally, expands over the anterior surface of the MD and then continues posterior as thin dispersed strips on either side of the mammillothalamic tract (MTT).
