Nicotinic acetylcholine receptors in the anterior, but not posterior, ventral tegmental area mediate ethanol-induced elevation of accumbal dopamine levels.
Ethanol-induced elevations of accumbal dopamine levels have been linked to the reinforcing properties of the drug. However, it has not yet been demonstrated where the primary point of action of ethanol is in the mesolimbic dopamine system, and there appear to be conflicting findings depending on methodology (electrophysiology, microdialysis, or intracranial self-administration). We have suggest...
متن کاملConcomitant Release of Ventral Tegmental Acetylcholine and Accumbal Dopamine by Ghrelin in Rats
Ghrelin, an orexigenic peptide, regulates energy balance specifically via hypothalamic circuits. Growing evidence suggest that ghrelin increases the incentive value of motivated behaviours via activation of the cholinergic-dopaminergic reward link. It encompasses the cholinergic afferent projection from the laterodorsal tegmental area (LDTg) to the dopaminergic cells of the ventral tegmental ar...
متن کاملThe Involvement of Intra-Hippocampal Dopamine Receptors in the Conditioned Place Preference Induced By Orexin Administration into the Rat Ventral Tegmental Area
The activity of dopamine (DA)-containing neurons in the ventral tegmental area (VTA) is a key mechanism in mesolimbic reward processing that has modulatory effects on different diencephalic structures like hippocampus (HIP), and receives inhibitory feedback and excitatory feed forward control. In addition, within the hippocampus, DA receptors are mostly located in the dorsal part (CA1) and dopa...
متن کاملNicotine Control of Dopamine Signaling in the Ventral Tegmental Area
Midbrain dopaminergic (DA) neurons signal motivational properties of natural reinforces and addictive drugs. Nicotine, like other drugs of abuse, boosts DA output from the ventral tegmental area (VTA). This increase results from direct stimulation of nicotinic acetylcholine receptors (nAChRs) expressed in the VTA. However, how the DA signal is constructed in the VTA and how nicotine changes thi...
متن کاملLocomotor activation induced by infusion of endorphins into the ventral tegmental area: evidence for opiate-dopamine interactions.
beta-Endorphin in nanomole quantities produced a stimulation of locomotor activity when infused into the region of the dopamine cell bodies of the ventral tegmental area (VTA) in rats. alpha-, gamma-, and des-Tyr-gamma-endorphin produced similar effects, but the D-alanine analogues of alpha and gamma-endorphin produced a larger and longer-lasting activation, presumably reflecting their resistan...
