sSC LTP in narrow-field vertical neurons is induced by SO stimulation at 20 Hz for 20 s. A, Confocal images of Texas Red staining for biocytin loaded in sSC narrow-field vertical neurons recorded in whole-cell mode. Scale bars, 40 μm. B, Representative LTP induction with 20 Hz for 20 s stimulation in a single neuron. Data points represent the EPSP slope before and after induction (arrow). Traces represent averages of 30 responses obtained during 10 min of baseline (1) and 25–35 min after LTP induction (2). C, Summary of all LTP experiments using the 20 Hz for 20 s induction stimulus. Data points represent mean EPSP slope (±SEM; n = 15). The mean EPSP slope (t = 25–35 min after induction) was significantly elevated to ± 6.2% over the baseline value (t = 0–10 min).
