amygdalaandhippocampus. This subset of projections is known as the mesolimbic dopaminergic system. Cells in the medial VTA project to the prefrontal, cingulate andperirhinal cortex. This pathway is known as the mesocortical dopaminergic system. There is considerable overlap between the VTA cells that ...
Tyrosine hydroxylaseis the rate-limiting enzyme of catecholamine synthesis that mediates thehydroxylationof tyrosine to L-DOPA. Thecatecholaminesdopamine, adrenaline and noradrenaline are the products of the pathway (Molinoff and Axelrod, 1971;Nagatsu et al., 1964). L-DOPA is converted into dopamine...

Behavioural activity was mea- sured and videotaped using a high definition camera (25000 images/sec) that detected changes in contrast and hence movement of mice. Mice were not acclimatised to the boxes prior to testing and boxes were cleaned thor- oughly to avoid olfactory clues. Animal ...
Therefore, taken together, our results suggest that PTTG increment in estrogen-induced prolactinomas is not related to the deficient dopaminergic control of the pituitary found in this model, but to another estrogenic pathway. We measured pituitary estrogen receptors in order to establish a link with...
The mesolimbic dopaminergic pathway is the major reward pathway of the brain. As a result, dysfunctions in the dopaminergic systems are involved in several pathological conditions including Parkinson’s disease, Tourette’s syndrome, drug addiction, and hyperactivity disorders.
