Here we show that EPSP-spike pairing at 6 Hz can optimally induce STDP at the mossy fiber-granule cell synapse in rats. WebDec 6, 2001 · (C) EPSP-spike coupling is less precise in pyramidal cells. EPSP-like test pulses are much less effective in activating outward currents near threshold (green trace). But in a circuit context, the rapid recruitment of synaptic inhibition produces a biphasic signal restricting spike generation to a window of duration of several milliseconds. sunova nz
