Amperometric analysis of endogenous levels of DA in NAccore and in NAcshell. Data are expressed in percentage of the basal DA values preceding treatment(s). The last 15 min out of 30 min of basal recordings are illustrated: TOP: the arrow indicates the acute i.p. injection of vehicle (cavasol 10 %, open circles, n = 4) or that of SB-277011-A (10 mg/kg, black squares, n = 4). BOTTOM: the arrow indicates acute i.p. injection of vehicle (cavasol 10%, n = 4 each area) OR cocaine (15 mg/kg., n = 3 each area). Data are presented as mean ± SD.
