Fig. 1. Study design.
In protocol #1, animals were treated with P (25 mg/kg, s.c., twice daily) for 2 weeks, followed by a P-free (withdrawal) period. In protocol #2, animals were treated with P for 2 weeks, followed by a 1 week washout period. In both studies, animals were kindled daily (except during washout period) until they exhibited three consistent stage 5 seizures.
