LTP in rat hippocampal slices prepared at 2, 7, and 14 days post-TBI. (A–C) Time plots showing mean ± SEM normalized EPSP slopes recorded in CA1 stratum radiatum of hippocampal slices prepared from ipsilateral (Ipsi.) and contralateral (Contra.) hemispheres. Arrows indicate the delivery of two 1 s duration 100 Hz trains (arrows) for LTP induction. n = 4–7 rats per post-injury time point. (D) Mean ± SEM LTP during the last 10 min of the post-100 Hz stimulus baseline (normalized to the pre-100 Hz stimulus baseline) as a function of hemisphere and post-injury time point.
