Mean percent freezing in Experiments 3a and 3b depicted for Pre (black) and No Pre (white) groups across drug treatment conditions when administered before (Panel 4A, MK-801 vs. Control) or after preexposure (Panel 4B, MK-801 Post). Bars represent standard errors of the mean. The CPFE was observed for Control and MK-801 Post groups, but not when MK-801 was infused prior to pre-exposure, implicating hippocampal NMDA receptors in the formation of the context memory early in ontogeny.
