Experiment 2: Inactivation of the mPFC during learning of a second list of conflicting odor discrimination problems. (A) Percent correct data are shown for the final day of training on list 1 (Last) and during the five training sessions of list 2, for control (open symbols) and muscimol (filled symbols) rats, and for the different context (squares) and same context (circles) rats. The rats were given infusions prior to the first three training sessions (indicated by the box). No infusions were given during the fourth and fifth sessions. (B) The interference index, reflecting the decline in performance from list 1 to list 2, is shown for control and muscimol rats. (C) The numbers of perseverative (black bars) and nonperseverative (white bars) errors made during the infusion sessions are shown for control and muscimol rats. (D) Cannula placements are shown for the rats in Experiment 2 (symbols as in A). (Atlas plates were adapted from Fig. 8 in Paxinos and Watson 1998, with permission from Elsevier © 1998.)
