Open field exploration 1-7 days after SE. Rats who experienced SE at P15, P21, or P30 exhibited significant alterations in exploratory behavior compared to controls during the postictal period (p<0.05 in P15 and P21, p<0.001 in P30; paired t-tests). A. P15-SE rats were hyperexploratory relative to controls at 1 d after SE (*p<0.05, Student's t-test; n=6, controls; n= 9, SE), but recovered rapidly. B. P21-SE rats exhibited significantly decreased exploration compared to controls for 3 days post SE (**p<0.01, ***p<0.001, Student's t-test; n=12, controls; n=7, SE). C. P30-SE rats remained hypo-exploratory until 5 days post-SE (**p<0.01, ***p<0.001, Student's t-test, n=10, controls; n=6, SE).
