Glutamate 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 کاملCoexpressed D1- and D2-like dopamine receptors antagonistically modulate acetylcholine release in Caenorhabditis elegans.
Dopamine acts through two classes of G protein-coupled receptor (D1-like and D2-like) to modulate neuron activity in the brain. While subtypes of D1- and D2-like receptors are coexpressed in many neurons of the mammalian brain, it is unclear how signaling by these coexpressed receptors interacts to modulate the activity of the neuron in which they are expressed. D1- and D2-like dopamine recepto...
متن کاملNMDA 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 کاملGlutamate receptors in nucleus accumbens mediate regionally selective increases in cortical acetylcholine release.
The basal forebrain cortical cholinergic system (BFCS) is critical for the regulation of attentional information processing. BFCS activity is regulated by several cortical and subcortical structures, including the nucleus accumbens (NAC) and prefrontal cortex (PFC). GABAergic projection neurons from NAC to basal forebrain are modulated by Glu receptors within NAC. We previously reported that in...
متن کاملOpposing role of dopamine D1 and D2 receptors in modulation of rat nucleus accumbens noradrenaline release.
The role of dopamine receptors in the modulation of nucleus accumbens noradrenaline release was investigated in superfused rat brain slices. At concentrations of </=1 microM, dopamine enhanced, whereas at higher concentrations dopamine inhibited electrically evoked [3H]noradrenaline release. The D1 receptor agonist SKF-38393 increased, whereas the D2 agonist quinpirole inhibited evoked [3H]nora...
