| The rise in membrane potential due to an EPSP is called depolarisation. In contrast, Inhibitory Post-Synaptic Potentials (IPSPs) render cell firing less likely by lowering the membrane potential, thereby pushing it further from the threshold level for action potential propagation. This lowering of the potential across the membrane is called hyperpolarisation. It is the summated effects of these depolarisations and hyperpolarisations (which may collectively be termed Neural Current Sources), rather than the action potentials themselves, that are recorded by EEG and ERPs. | The rise in membrane potential due to an EPSP is called depolarisation.
