The effect of GABAB receptor activation within the ventral tegmental area on morphine-induced incentive sensitization in female rats
Repeated administration of morphine sensitizes animals to the stimulant and rewarding properties of the drug. It may also alter the expression and function of GABA receptors within the ventral tegmental area (VTA), a midbrain region that is implicated in morphine action. In the present study, the effect of activation of GABAB receptor subtypes within the VTA on morphine-induced incentive sensit...

متن کاملEvaluation of GABA Receptors of Ventral Tegmental Area in Cardiovascular Responses in Rat
Background: The ventral tegmental area (VTA) is well known for its role in cardiovascular control. It is demonstrated that about 20-30% of the VTA neurons are GABAergic though their role in cardiovascular control is not yet understood. This study is carried out to find the effects of GABA A and GABA B receptors on cardiovascular response of the VTA. Methods: Experiments were performed on uretha...
متن کاملActivation of the ventral tegmental area increased wakefulness in mice
The ventral tegmental area (VTA) is crucial for brain functions, such as voluntary movement and cognition; however, the role of VTA in sleep-wake regulation when directly activated or inhibited remains unknown. In this study, we investigated the effects of activation or inhibition of VTA neurons on sleep-wake behavior using the pharmacogenetic "designer receptors exclusively activated by design...
متن کاملD1 receptors modulate glutamate transmission in the ventral tegmental area.
Perfusion of the D1 agonist, SKF-82958, through a microdialysis probe implanted in the ventral tegmental area produced a dose-dependent increase in extracellular glutamate and GABA. The increase in extracellular glutamate occurred at approximately 30x lower dose than the elevation in GABA. The increase in extracellular glutamate by SKF-82958 was blocked by coperfusion of the D1 antagonist, SCH-...
