ventrobasal complex

[TA]
the large posterior part of the ventral nucleus of the thalamus receiving the somatic sensory lemnisci (medial lemniscus, spinothalamic tract, and trigeminal lemniscus) and the ascending gustatory (taste) lemniscus and projecting in turn by way of the internal capsule to the cortex of the postcentral gyrus. This complex of nuclei is somatotopically organized and subdivided into a ventral posterolateral nucleus [TA] (nucleus ventralis posterolateralis [TA]) representing the lower extremity, a ventral posterior intermediate nucleus representing the upper extremity, and a ventral posteromedial nucleus [TA] (nucleus ventralis posteromedialis [TA]) representing the face and an arcuate nucleus of thalamus receiving the gustatory lemniscus.

These afferent neural pathways lead from the receptors to the brain and spinal cord, then travel to the ventrobasal complex of the thalamus, and is processed in the somatosensory cortex in our brain.
