Effects of PFC–N.Acc. disconnections on performance of the delayed SWSh task. A, Number of errors (mean ± SEM) made by rats on the day before the first injection (open bar) and after unilateral infusions of saline into both the PFC and the N.Acc. (hatched bar), unilateral infusions of lidocaine (Lido) into the PFC and contralateral saline in the N.Acc. (gray bar), unilateral infusions of Lido into the N.Acc. and contralateral saline into the PFC (striped bar), and unilateral Lido into the N.Acc. and contralateral Lido into the PFC (disconnection; black bar) before the test phase of the delayed SWSh task. ★★Significance atp < 0.001 versus all other treatment conditions.Inset, Number of across-phase (cross-hatched bar) versus within-phase (striped bar) errors made by rats duringLido/Lido (disconnection) injection days.B, Location of cannulae tips (black circles) for all rats used for data analysis receiving PFC–N.Acc. disconnections before the delayed SWSh task. Plates are computer generated adaptations from Paxinos and Watson (1986).Numbers beside each plate correspond to millimeters from bregma.
