Pairing protocol purely induce post-LTP. (a) Top: sample traces of EPSCs with paired-pulse stimulation during baseline (1) and 60 min after the pairing protocol (2) at a holding membrane potential of −60 mV. Bottom: a time course plot of a representative single example. (b) Pooled data to illustrate the time course of PPR (n = 7/5). (c) Summary of PPR data before and after the pairing protocol. There is no significant difference between before and after (paired t-test, t₆ = -0.64, p > 0.05). Calibration, 100 pA, 50 ms. The arrow denotes the time of pairing protocol.
