Ca2+ sensitivity of ΔSpH. a Sample records of fEPSP evoked by a two-pulse protocol (interval, 100 ms) at 0.033 Hz in an ACSF containing [Ca2+]o at 2.5 mM (top trace), 5 mM (middle trace) or 0 mM (bottom trace). b [Ca2+]o dependence of fEPSP (n = 8 slices). c Sample records of ΔSpH from a LMFB by a train of repetitive stimulation (10 Hz for 10 s); [Ca2+]o at 2.5 mM (top trace), 5 mM (middle trace) or 0 mM (bottom trace). d [Ca2+]o dependence of ΔSpH (n = 12 boutons, 3 slices)
