... time. Both EPSPs and IPSPs differ from action potentials in that they are subthreshold responses that decay very rapidly in time and space. Whether or not the acted-on neuron will fire (action potential triggered) depends on the integration of all EPSP and IPSP activity at any given moment at the ax ...
