Peak freezing (mean ± SEM) was computed by taking each rat’s maximum freezing for any continuous minute during each of the 8-min context and 6-min (post-baseline) tone fear tests. Paired comparisons contrast context and tone freezing within-subjects using the Wilcoxon signed-rank post hoc; unpaired comparisons contrast Sham and DH groups for each test using the Mann–Whitney U post hoc. For both Experiments 1 and 2, DH lesions produced significant impairments in average (Figs. 3-5) and peak (above) recent context fear but not remote context or tone fear. For Sham animals, peak (above) and average (Figs. 3-5) context fear was greater than, or equivalent to, but not weaker than tone fear.
