Postsynaptic potentials manifested current effect and frequency dependency and their IPSP displayed a prolonged inhibition.
突触后电位表现电流效应和频率依赖性，其IPSP具有长时程的抑制作用。
2
Their average amplitudes were differentially up - or down-regulated, depending on the precise timing of postsynaptic APs relative to EPSPs.
它们的平均振幅是依赖精确的后突触ap与EPSP时间，相差性的上下控制。
3
Chemical synapses also serve to amplify neuronal signals, so that even a small presynaptic nerve terminal can alter the response of a large postsynaptic cell.
