Injury to tegmental
regions of the upper pons and midbrain increases the likelihood of initial disturbances in consciousness, but CT scans completed in the acute stage of injury are limited in their capacity to detect edema or regional infarction in these brain structures.
It connects (amongst others) the ventral tegmental
area (VTA) bidirectionally with the nucleus accumbens (NAC) and the medial prefrontal cortex (mPFC).
While analysing the link between physical features of men and their involvement as a father, researchers found that fathers with smaller testicular volume showed better activity in the brain area related to reward and parental motivation - the ventral tegmental
area (VTA) while viewing their child's photos.
These cells, which produce the chemical messenger dopamine, nestle in a brain region called the ventral tegmental
area, a spot known for handling rewards.
For example, alcohol administration elevates 5-HT levels in the nucleus accumbens, ventral tegmental
area (VTA), amygdala, and hippocampus, an effect that is more pronounced in alcohol-preferring rats.
Ademas de lo anterior, el cuerpo estriado dorsal se proyecta sobre el sistema nigroestriado y el cuerpo estriado ventral recibe fibras dopaminergicas desde el area ventral "tegmental
In the glutamate hypofunction model of psychosis, a GABAB agonist would cause disinhibition of glutamate modulation of mesolimbic dopamine and reversal of GABA transmission in the ventral tegmental
The reward system in the brain involves neurons of the prefrontal cortex, nucleus accumbens, amygdala, ventral tegmental
area (VTA, a region in the midbrain), the substantia nigra (a thin black layer separating the anterior and posterior portions of the midbrain) and the locus ceruleus (a small blue-hued area on both sides of the upper posterior region of the pons).
The red nucleus and the ipsilateral inferior olivary nucleus are connected via the central tegmental
tract, and the dentate nucleus connects to the contralateral red nucleus through the superior cerebellar peduncle.
When discussing the neurobiology that underlies the plastic changes associated with AOD use, Kalivas and O'Brien (2008) focused on the initial release of the neurotransmitter dopamine from cells in the brain region called the ventral tegmental
area (VTA) that is induced by addictive drugs.
