abstract:
We propose addiction model based on optogenetic dopamine neuron self-stimulation (oDASS) of the ventral tegmental area (VTA). We show that oDASS leads to neural and behavioral adaptations typically observed after prolonged drug exposure, including compulsive self-stimulation despite negative consequences. We demonstrate the power of oDASS to investigate molecular and cellular alterations in identified neurons of a disease relevant neural circuit with the goal to reveal the mechanism underlying individual vulnerability to drugs.
