Dopamine release in the nucleus accumbens (shell) of two lines of rats selectively bred to prefer or avoid ethanol
(2007)
Lower tissue levels of dopamine and 5-hydroxytryptamine (5-HT) have been found in the nucleus accumbens of alcohol-naïve rats selectively bred to prefer ethanol than in rats bred to avoid it. These findings have led to the ...
Involvement of dopaminergic mechanisms in the nucleus accumbens core and shell subregions in the expression of fear conditioning
(ELSEVIER IRELAND LTD, 2008)
The involvement of dopamine (DA) mechanisms in the nucleus accumbens (NAC) in fear conditioning has been proposed by many studies that have challenged the view that the NAC is solely involved in the modulation of appetitive ...
NMDA antagonist MK 801 in nucleus accumbens core but not shell disrupts the restraint stress-induced reinstatement of extinguished cocaine-conditioned place preference in rats
(Elsevier Science, 2016-12)
Relapse is a common feature of cocaine addiction. In rodents, it can be elicited by cues, stress or the drug. Restraint stress-induced reinstatement of cocaine-conditioned place preference (CPP) is a useful model to study ...
Cross-sensitization between cocaine and acute restraint stress is associated with sensitized dopamine but not glutamate release in the nucleus accumbens
(Wiley Blackwell Publishing, Inc, 2013-03)
Repeated administration of psychostimulant drugs or stress can elicit a sensitized response to the stimulating and reinforcing properties of the drug. Here we explore the mechanisms in the nucleus accumbens (NAc) whereby ...
Effects of CB1 Cannabinoid Receptor activation in the nucleus Accumbens Shell on feeding behavior
(Universidad Católica de Colombia. Facultad de Psicología, 2014-07)
A obesidade e suas patologias relacionadas são riscos de saúde muito conhecidos. Ainda que a obesidade e o sobrepeso possuam causas multifatoriais, a sobre ingestão de alimento é frequente nestas condições. De acordo com ...
