Note the unitary EPSPs of enormous amplitude selectively targeting fast-spiking interneurons. Inset, amplitude distribution of spontaneous EPSPs arriving at presynaptic human pyramidal cells (red) and postsynaptic interneurons (blue). The distribution of spontaneous EPSPs was shifted towards significantly higher amplitudes in interneurons relative to pyramidal cells.
