<prompt> The peak of fast EPSP or, fast IPSP is seen at what time after stimulus application:0.5 ms0.5 to 1.5 ms11.5 ms100-500 ms  <response>: Fast EPSP and fast IPSP begins 0.5 ms after the stimulus known as latency. They peak 1-1.5 ms after the stimulus then decreases exponentially. Fast EPSP is due to influx of Na and or Ca in post synaptic neuron. Fast IPSP is due to influx of Cl- in post synaptic neuron.
