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 dorsal raphe nucleus is located on the midline of the brainstem and is part of the raphe nucleus, consisting of the rostral and caudal subdivisions.1  The rostral aspect of the dorsal raphe is further divided into interfascicular, ventral, ventrolateral and dorsal subnuclei.he rostral raphe nuclei, both the median raphe nucleus and particularly the dorsal raphe nucleus have long been implicated in depression. Some studies have suggested that the dorsal raphe may be decreased in size in people with depression and, paradoxically, an increased cell density in those who commit suicide.
