- ItemExposure to repeated immobilization stress inhibits cocaine-induced increase in dopamine extracellular levels in the rat ventral tegmental area(2015) Sotomayor-Zarate, Ramon; Abarca, Jorge; Araya, Katherine A.; Renard, Georgina M.; Andres, Maria E.; Gysling, KatiaA higher vulnerability to drug abuse has been observed in human studies of individuals exposed to chronic or persistent stress, as well as in animal models of drug abuse. Here, we explored the effect of repeated immobilization stress on cocaine-induced increase in dopamine extracellular levels in VTA and its regulation by corticotropin-releasing factor (CRF) and GABA systems.
