Figure 1. MMP inhibition with FN-439 treatment prior to conditioning in the shock chamber does not block subsequent freezing in response to the tone CS.

Figure 1

A. Experimental timeline. B. Data are mean ± SEM of percent freezing. Percent freezing = percent freezing in the absence of tone presentation (Pre-CS) followed by percent freezing in the presence of tone presentation (CS). Tests were conducted 24 hr and 7 days after conditioning. I.C.V. infusion of aCSF or FN-439 was done 30 min prior to the conditioning session in the shock box. N = 6 for aCSF group; N = 8 for FN-439 group.
