High-frequency stimulation of the unilateral side of the Dl evoked long-term potentiation (LTP) in the ipsilateral and contralateral side of the Dm. (a) LTP of the contralateral side of the Dm (group data). (b) LTP of the ipsilateral side of the Dm (group data). High-frequency stimulation (100 Hz) was applied (arrow) in the Dl division. The amplitude of the PS of both sides after LTP induction was 1.5 times larger than the amplitude at baseline, and this increase could last at least 1 hour. Using paired t-test to compare the amplitude at 60 min (point 2) with the amplitude at baseline (point 1): (193.89 ± 17.31%, n = 8, p = 0.0010; ipsilateral: 164.83 ± 16.05%, n = 8, p = 0.0012). Each point represents the mean ± SEM of the PS amplitude. n = 8.
