Fast and slowly rising mEPSCs in CA1 pyramidal neuron. A. Example traces of mEPSCs from three different slices show different rise time of mEPSCs recorded from CA1 pyramidal neuron. F is fast rising mEPSCs, and s is slowly rising mEPSCs. B. The histogram of rise times of 240 mEPSCs recorded from 3 cells for 8 minutes. Fast rise time of mEPSCs is 1 ~ 5 ms, and slow rise time of mEPSCs is 5 ~ 10 ms. C. Schematic diagram of fast rising and slowly rising mEPSCs. Somatic region of CA1 pyramidal neurons is whole cell patched under voltage clamp (holding potential −60 mV).
