Systemic administration of DCS did not potentiate reversal learning in rats. After acquiring a CFTP (as shown on test day 0), rats were reverse conditioned with alternate daily presentations of the previous CS+ flavor now mixed with saccharin (rCS−, black symbols) and the previous CS− now mixed with fructose (rCS+, white symbols). Preferences were assessed after every 4 reverse conditioning days (test days 1 – 4). In both groups, preference for the rCS−/S decreased while preference for the rCS+/S increased during reverse conditioning. Pretreatment during reverse conditioning with either vehicle (circles) or DCS (squares) had no effect on the magnitude or time course of reversal learning. * p < 0.05 vs. own rCS+.
