Figure 3. Effects of kainate treatment on the acquisition and retention of conditioned fear.

The y-axes represent percentage of freezing time for each of the 3-minute periods of the acquisition session (A), during the context retention test (B), and during each of the 3-minute periods of the tone retention test which was performed in a novel context (C). No tone or footshock was delivered during the first 3-minute periods of the acquisition session (A) and of the tone retention test (C). Note that rats that had experienced behavioral status epilepticus (BSE group) showed reduced levels of fear, freezing significantly less than control rats on both retention tests. However, no-BSE group (composed of rats that had not experienced behavioral status epilepticus after kainate treatment) and control group did not differ significantly on these tests. *p<0.05 vs. control group and ^# p<0.05 vs. no-SE group. Data are presented as the mean±SEM.
