Stimulation of endorphin neurotransmission in the nucleus accumbens by ethanol, cocaine, and amphetamine.
Numerous studies have demonstrated that drugs of abuse activate the mesolimbic dopamine reward pathway, and it is widely held that this activation contributes to the motivational and positive reinforcing properties of these substances. However, there is evidence that endogenous opioid systems within this brain reward circuit also play a role in drug reinforcement and drug-seeking behavior. Usin...
متن کاملExtinction of Cocaine Self-Administration Reveals Functionally and Temporally Distinct Dopaminergic Signals in the Nucleus Accumbens
While Pavlovian and operant conditioning influence drug-seeking behavior, the role of rapid dopamine signaling in modulating these processes is unknown. During self-administration of cocaine, two dopaminergic signals, measured with 100 ms resolution, occurred immediately before and after the lever press (termed pre- and post-response dopamine transients). Extinction of self-administration revea...
متن کاملRole of NO-ergic system of the he nucleus accumbens in metabolic disturbances under acute stress
Introduction: The aim of the study was to evaluate the involvement of nitricergic system within the shell part of the nucleus accumbens (NAc) by injection of L-arginine, a nitric oxide precursor, and L NAME, a nitric oxide synthase inhibitor in the metabolic disturbances induced by acute stress in the male rat. Materials and Methods: Male Wistar rats were cannulated unilaterally in the left par...
متن کاملRats that differentially respond to cocaine differ in their dopaminergic storage capacity of the nucleus accumbens
Cocaine (COC) inhibits the re-uptake of dopamine. However, the dopamine response to COC also depends on dopamine inside storage vesicles. The aim of this study was to investigate whether rats that differentially respond to COC differ in their dopaminergic storage capacity of the nucleus accumbens. Total and vesicular levels of accumbal dopamine as well as accumbal vesicular monoamine transporte...
