Brain: Ventral anterior nucleus
Thalamic nuclei:
MNG = Midline nuclear group
AN = 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 nucleus
Latin nucleus ventralis anterior thalami
NeuroNames hier-317
Dorlands/Elsevier n_11/12583946

The ventral anterior nucleus is a nucleus of the thalamus.

Inputs and outputs

receives neuronal inputs from the basal ganglia which includes the substantia nigra and the globus pallidus. It also has inputs from the cerebellum. It sends out neuronal input to the supplementary motor cortex.

Functions

It helps to function in planning movement. It initiates wanted movement and inhibits unwanted movement.
