ventral posteromedial nucleus ventral posteromedial nucleus the ventral posteromedial nucleus (vpm) is a nucleus of the thalamus. ventral posteromedial nucleusthalamic nuclei: mng = midline nuclear groupan = anterior nuclear group md = medial dorsal nucleus vng = ventral nuclear group va = ventral anterior nucleus vl = ventral lateral nucleus vpl = ventral posterolateral nucleus vpm = ventral posteromedial nucleus lng = lateral nuclear group pul = pulvinar mth = metathalamus lg = lateral geniculate nucleus mg = medial geniculate nucleusthalamic nucleidetailsidentifierslatinnucleus ventralis posteromedialis thalamineuronames347neurolex idbirnlex_743ta98a14.1.08.642ta25693fma62202anatomical terms of neuroanatomy inputs and outputs the vpm contains synapses between second and third order neurons from the anterior (ventral) trigeminothalamic tract and posterior (dorsal) trigeminothalamic tract. these neurons convey sensory information from the face and oral cavity. third order neurons in the trigeminothalamic systems project to the postcentral gyrus. the vpm also receives taste afferent information from the solitary tract and projects to the cortical gustatory area. subareas vpmpc the parvicellular part of the ventroposterior medial nucleus (vpmpc) is argued by some as not an actually part of the vpm, because it does not project to the somatosensory cortex as the remainder of the vpm does, and therefore should be called the ventromedial nucleus (vmb) instead. sources kiernan, j., & rajakumar, r.
