ventral anterior nucleus ventral anterior nucleus the ventral anterior nucleus (va) is a nucleus of the thalamus. it acts with the anterior part of the ventral lateral nucleus to modify signals from the basal ganglia. ventral anterior 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 anterior thalamineuronames334neurolex idbirnlex_1232ta98a14.1.08.652ta25688fma62184anatomical terms of neuroanatomy inputs and outputs the ventral anterior nucleus receives neuronal inputs from the basal ganglia. its main afferent fibres are from the globus pallidus. the efferent fibres from this nucleus pass into the premotor cortex for initiation and planning of movement. functions it helps to function in movement by providing feedback for the outputs of the basal ganglia. additional images thalamus thalamus
