excitatory postsynaptic potentialGo to external page http://purl.obolibrary.org/obo/GO_0060079
A process that leads to a temporary increase in postsynaptic potential due to the flow of positively charged ions into the postsynaptic cell. The flow of ions that causes an EPSP is an excitatory postsynaptic current (EPSC) and makes it easier for the neuron to fire an action potential.
Synonyms: regulation of excitatory post-synaptic membrane potential
- regulation of postsynaptic membrane potential
- part of some chemical synaptic transmission, postsynaptic
