Behavioral demonstration of sensory preconditioning (experiment 4) and effect of BLA inactivation and MK-801 on the acquisition of sensory preconditioning (experiment 5). The left panel shows mean + SEM levels of freezing to S2 at test for groups PP (filled squares), PU (open squares), and UP (filled circles), muscimol- and vehicle-treated rats (middle panel), and MK-801-treated and vehicle-treated rats (right panel). Drug-treated rats are shown with filled squares, and vehicle-treated rats are shown with open squares.
