  1. L'area tegmentale ventrale (dal latino tegmentum, ossia rivestimento), conosciuta anche come ventral tegmental area (VTA), è un gruppo di neuroni localizzato in vicinanza della linea mediana sul pavimento del mesencefalo. Nella VTA sono contenuti i pirenofori di neuroni dopaminergici appartenenti al sistema mesolimbico dopaminergico ed è ...

  2. Dorsal and ventral. These two terms, used in anatomy and embryology, describe something at the back (dorsal) or front/belly (ventral) of an organism. The dorsal (from Latin dorsum 'back') surface of an organism refers to the back, or upper side, of an organism. If talking about the skull, the dorsal side is the top.

  3. May 03, 2022 · This study demonstrates the selective role of a ventral tegmental area dopamine projection to the amygdala for cocaine induced anxiety, but not cocaine reward or sensitization. Silencing this projection prevents development of anxiety during protracted withdrawal after cocaine use. 85 percent of individuals relapse and return to drug use within ...

  4. spinothalamic tract, and central tegmental tract. This region also contains the trapezoid body, part of the auditory path-way involved in the localization of sound. The medulla oblongata relays information from the spinal cord to the brain and is composed of a ventral portion and a dorsal tegmentum. The ventral part includes the pyramids

  5. The mesolimbic pathway, sometimes referred to as the reward pathway, is a dopaminergic pathway in the brain. The pathway connects the ventral tegmental area in the midbrain to the ventral striatum of the basal ganglia in the forebrain.

  6. Oct 07, 2020 · The DLF is comprised of fibers originating from several brainstem nuclei, which are serotonergic (5-HT) from neurons located within the nucleus raphe magnus (NRM); dopaminergic neurons originating from ventral tegmental area (VTA) and adrenergic neurons originating from the locus coeruleus (LC).

  7. Apr 17, 2021 · Specifically, N2 receptors are present in the adrenal medulla, on the postsynaptic cell bodies of neurons within the sympathetic and parasympathetic nervous systems, as well as in various locations in the brain such as the ventral tegmental area, hippocampus, prefrontal cortex, amygdala, and the nucleus accumbens.
