The neurons of the ventral posterior nucleus project to
A) SI, SII, and the posterior parietal cortex.
B) the thalamus.
C) the medial lemniscus.
D) the dorsal column nuclei.
E) the auditory cortex.

Question

Quizplus · Accepted Answer

The ventral posterior nucleus of the thalamus is involved in processing somatosensory information, and its neurons project primarily to the primary (SI) and secondary (SII) somatosensory cortex, as well as the posterior parietal cortex. Therefore, choice A is the best answer. The medial lemniscus and dorsal column nuclei are involved in the transmission of sensory information to the thalamus, but the ventral posterior nucleus does not project to them directly. The auditory cortex is involved in processing auditory information and is not directly related to the ventral posterior nucleus.
