Correlation between short-interval intracortical inhibitory (SICI) and the after-effect of intermittent theta burst stimulation (iTBS)-induced long-term potentiation (LTP)-like plasticity. (A) There was a significant negative correlation between the amount of SICI measured before iTBS and the after-effect of iTBS-induced LTP-like plasticity at the time point of 5 min [R² = 0.44, p < 0.05, false discovery rate (FDR) corrected]. (B) The correlation between the level of SICI before stimulation and iTBS-induced after-effects at 10 min after conducting iTBS was also significant (R² = 0.43, p < 0.05, FDR corrected). (C) A significant negative correlation was also reported between the amount of SICI before stimulation and the iTBS-induced effects at 15 min after stimulation (R² = 0.45, p < 0.05, FDR corrected). (D) There was no significant correlation between SICI before stimulation and iTBS effect at 30 min (R² = 0.08, p = 0.107, FDR corrected).
