A glutamatergic reward input from the dorsal raphe to ventral tegmental area dopamine neurons
Electrical stimulation of the dorsal raphe (DR) and ventral tegmental area (VTA) activates the fibres of the same reward pathway but the phenotype of this pathway and the direction of the reward-relevant fibres have not been determined. Here we report rewarding effects following activation of a DR-originating pathway consisting of vesicular glutamate transporter 3 (VGluT3) containing neurons th...
متن کاملThe 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 کاملMultiple Personalities in the Ventral Tegmental Area
A small number of ventral tegmental area dopamine neurons engage in numerous and apparently contradictory functions--how can this be? A clue is provided by Lammel and colleagues in this issue of Neuron: some VTA dopamine neurons display synaptic plasticity in response to cocaine, and others in response to pain, and these populations are distinguished by their axonal projections and Ih.
