Figure 1.
IGF2 injected into the BLA has no effect on AFC memory. Experimental schedule is shown above the figure. (A) AFC memory retention is expressed as the percent freezing ± SEM of rats given a bilateral amygdala injection (arrow) of vehicle or IGF2 immediately after AFC training (Tr). Retention was tested at 24 h (Test 1) after training (n = 9). (B) IA memory retention is expressed as the mean latency ± SEM (in seconds) of rats given a bilateral hippocampal injection (arrow) of vehicle or IGF2 immediately after testing (Test 1) given 24 h after IA training (Tr). Retention was tested 24 h (Test 2) later (n = 5). (***) P < 0.001.
