Answer: Neurotransmitter-gated receptors can open separate ion channels. Opening a sodium channel would result in an EPSP, while opening a potassium channel would result in an IPSP. The critical event which produces an action potential is reaching the threshold value for the membrane. EPSPs move the potential closer to that value; IPSPs move it further away. The PSPs can add together spatially and temporally, because of the residual nature of these potentials.
