KCNQ channel openers reverse depressive symptoms via an active resilience mechanism

open access: yesNature Communications, 2016
Potassium channels in the ventral tegmental area are known to regulate resilience against stress-induced depression. Here, the authors show over expression of KCNQ3 channels in VTA dopaminergic neurons or treatment with KCNQ channel openers normalizes ...

The expression of Cre recombinase recapitulates that of Th in dopaminergic neurons in the ventral tegmental area and substantia nigra.

open access: yes, 2016
A combination of anti-TH immunostaining and Cre fluorescence in situ hybridization (A-A”, D-E”) as well as double fluorescence in situ hybridization with both Th and Cre riboprobes (B-C”) were employed to examine the co-localization of Cre mRNA and the ...

The projection from the prelimbic cortex to the ventral tegmental area negatively regulates 5-HT-induced itch-scratching and positively regulates itch-related aversion in rats

open access: yesBrain Research Bulletin
Direct and indirect evidence suggests that the prelimbic cortex (PrL) and the ventral tegmental area (VTA) are the key brain regions involved in the regulation of itch sensation and itch-related emotions.

Nicotine withdrawal in the rat: role of alpha7 nicotinic receptors in the ventral tegmental area

open access: yes, 1999
Previous data show that nicotinic receptors in the ventral tegmental area are of importance for the nicotine withdrawal syndrome. Here we have investigated the specific role of alpha7 nicotinic receptors in the ventral tegmental area for the ...

Determination of neurotensin projections to the ventral tegmental area in mice

open access: yesNeuropeptides, 2018
Pharmacologic treatment with the neuropeptide neurotensin (Nts) modifies motivated behaviors such as feeding, locomotor activity, and reproduction. Dopamine (DA) neurons of the ventral tegmental area (VTA) control these behaviors, and Nts directly modulates the activity of DA neurons via Nts receptor-1.

Distinct microcircuits in the dorsal raphe to ventral tegmental area projection pathway [PDF]

open access: yes, 2019
Dopamine and gamma-aminobutyric acid (GABA) neurons in the ventral tegmental area have been shown to be critically involved in motivational behavior. How these neurons encode the relevant features of motivational behavior to generate behavioral output is

The dual orexin/hypocretin receptor antagonist, almorexant, in the ventral tegmental area attenuates ethanol self-administration. [PDF]

open access: yes, 2012
Recent studies have implicated the hypocretin/orexinergic system in reward-seeking behavior. Almorexant, a dual orexin/hypocretin R(1) and R(2) receptor antagonist, has proven effective in preclinical studies in promoting sleep in animal models and was ...

NMDA and Ampa receptors in synaptic membranes of cocaine and cocaine-prazosin treated rats

open access: yesIatreia, 2005
Sensitization, an increase in behavioral responses after repeated exposure to stimulants, occurs in the mesocorticolimbic pathway that includes the ventral tegmental area (VTA), the nucleus accumbens (NAc), hippocampus and the prefrontal cortex (PFC).

Dopamine neuronal loss contributes to memory and reward dysfunction in a model of Alzheimer’s disease

open access: yesNature Communications, 2017
Dopaminergic dysfunction occurs in Alzheimer’s disease (AD). The authors show that in a mouse model of AD, loss of dopaminergic neurons in the ventral tegmental area, but not the substantia nigra, occurs at early pre-plaque stages, and may contribute to ...
