The rodent MFB stretches from the ventral tegmental
area (VTA) in the midbrain to several forebrain structures and includes both myelinated and short typically unmyelinated ascending and descending projections.
In addition to studying the nerve cells in the ventral tegmental
area, the researchers also explored the cells' external connections.
Dopaminergic neurons in the ventral tegmental
area (VTA) of the midbrain project to the nucleus accumbens and other limbic areas to form the mesolimbic dopamine system, the most studied reward circuit.
Es un area multifuncional para la cognicion, la adiccion a diversas sustancias y otras graves alteraciones psiquiatricas; el area ventral "tegmental
" contiene numerosas proyecciones hacia diferentes zonas cerebrales.
Evidence for a selective prefrontal cortical GABA(B) receptor mediated inhibition of glutamate release in the ventral tegmental
area: a dual probe microdialysis study in the awake rat.
When the primary lesion is in the central tegmental
tract, olivary degeneration is ipsilateral, as occurred in our patient.
Increased ethanol excitation of dopaminergic neurons of the ventral tegmental
area after chronic ethanol treatment.
Selective vulnerability of hippoeampal CA3 neurones after micro-infusion of paraquat into the rat substantia nigra or into the ventral tegmental
To accomplish this, dopamine release is electrically evoked with a stimulating electrode in the substantia nigra/ventral tegmental
area or the medial forebrain bundle.
Deister noted that imaging studies of brain pathways in IA have demonstrated that mesolimbic dopaminergic projections to the nucleus accumbens from the ventral tegmental
area are involved, as well as diminished activity of the ventral medial prefrontal cortex.
6-OHDA was injected into the right substantia nigra pars compacta (SNc) and ventral tegmental
area (VTA) of each group, except normal + NS, 60 days after the PX.
Led by Amy Lasek, researchers found that neurons in a region of the brain called the ventral tegmental
area, or VTA (also known as the "reward center"), fired most rapidly in response to alcohol when their estrogen levels were high.
