Intra-CA1 injection of plasticity blockers impairs the IA learning. (A) Experimental design of bilateral intra-CA1 injection and IA training. (B) Microinjection of AP5 or methyllycaconitine (Mla) into the dorsal CA1 impaired learning. (C) The injection into the ventral CA1 did not affect the performance. The number of rats in each group is shown at the bottom of each bar. Vertical gray and black bars indicate guide cannula and injector. The number indicates posterior coordinate from bregma. Error bars indicate + SEM. **P < 0.01 versus saline (Sal).
