PF stimulation at 32°C induces a lasting increase in the frequency of mIPSCs. A, Miniature synaptic currents recorded at −30 mV in the presence NBQX. B, Schematic diagram of the experimental protocol. C, Representative average current traces evoked by PF stimulation, without CPP (top two traces), before (third; the current was evoked by a single sweep of testing stimulation) and during the application of CPP. D, mIPSCs before and 30 min after PF stimulation. E, Plot of percentage change in mean mIPSC frequency versus time (n = 5). F, Plot of percentage change in mean mIPSC amplitude versus time (n = 5).
