Webgrand postsynaptic potential (GPSP) the total potential in the postsynaptic neuron, is … WebDefinition. An excitatory postsynaptic potential (EPSP) is the change in membrane voltage of a postsynaptic cell following the influx of positively charged ions into a cell (typically Na+) as a result of the activation of ligand-sensitive channels. This results in a depolarization of the postsynaptic cell, thus increasing the likelihood of ...
