The relative percent of convulsive (Racine stage 3 to 5) seizures during weeks 1, 2, and 3 of the EEG recording period was analyzed. In the first week of the recording period, the BCAA-treated rats had a lower relative percent of convulsive seizures compared with water-treated rats (p < 0.001). In week 2, there were no significant differences in the relative percent of convulsive seizures between the BCAA- and water-treated rats, whereas in week 3 the BCAA-treated rats had a higher relative percent of convulsive seizures (p < 0.05). Data is presented as percent of convulsive seizures. ***p < 0.001, *p < 0.05.
