If you are maintaining your current body weight, you are in caloric balance. If you need to gain weight or to lose weight, you'll need to tip the balance scale in one direction or another to achieve your goal.
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 hypothalamus is the ventral-most part of the diencephalon. As seen in Fig. 2 of the thalamus handout, the hypothalamus is on either side of the third ventricle, with the hypothalamic sulcus delineating its dorsal border. The ventral aspect of the hypothalamus is exposed on the base of the brain (Fig. 1).
