NMDA and dopamine interactions in the nucleus accumbens modulate cortical acetylcholine release.
The nucleus accumbens (NAC) plays a key role in directing appropriate motor output following the presentation of behaviorally relevant stimuli. As such, we postulate that accumbens efferents also participate in the modulation of neuronal circuits regulating attentional processes directed toward the identification and selection of these stimuli. In this study, N-methyl-d-aspartate (NMDA) and D1 ...
متن کاملNucleus accumbens acetylcholine regulates appetitive learning and motivation for food via activation of muscarinic receptors.
These experiments tested whether nucleus accumbens muscarinic or nicotinic acetylcholine receptor activation is required for rats to learn to lever press for sucrose. Muscarinic blockade with scopolamine (1.0 microg/side or 10.0 microg/side), but not nicotinic antagonism with mecamylamine (10.0 microg/side), inhibited learning and performance when applied to the core or shell. Further experimen...
متن کاملGlutamate Receptors in Nucleus Accumbens Can Modulate Canabinoid-Induced Antinociception in Rat’s Basolateral Amygdala
Introduction: It has been shown that administration of WIN55,212-2, a cannabinoid receptor agonist, into the basolateral amygdala (BLA), dose-dependently increases the thermal latency to withdrawal in the tail-.ick test and decreases pain related behaviors in both phases of the formalin test. Recent human and animal imaging data suggest that the nucleus accumbens (NAc) is an important neural su...
متن کاملAcute ethanol inhibits dopamine release in the nucleus accumbens via α6 nicotinic acetylcholine receptors.
Electrophysiology and microdialysis studies have provided compelling evidence that moderate to high ethanol concentrations enhance dopamine (DA) neurotransmission in the nucleus accumbens (NAc) through the mesolimbic DA system. However, with fast-scan cyclic voltammetry, short-term exposure to moderate to high doses of ethanol decreases evoked DA release at terminals in the NAc. The aim of this...
