The ventral posterior nucleus is the somato-sensory relay nucleus in thalamus of the brain. Ventral posterolateral nucleus, which receives sensory information from the body. 2  Ventral posteromedial nucleus, which receives sensory information from the head and face via the trigeminal nerve.
The paraventricular nucleus (PVN, PVA, or PVH) is a neuronal nucleus in the hypothalamus. It contains multiple subpopulations of neurons that are activated by a variety of stressful and/or physiological changes.mong these, inputs from neurons in structures adjacent to the anterior wall of the third ventricle (the AV3V region) carry information about the electrolyte composition of the blood, and about circulating concentrations of such hormones as angiotensin and relaxin, to regulate the magnocellular neurons.
