WebFeb 9, 2024 · EPSP is referred to as excitatory postsynaptic potential. It is an electrical charge that occurs within the post-synaptic membrane of the neuron as a result of excitatory neurotransmitters. EPSP creates an exciting environment within the post-synaptic membrane. This excitation results in the firing of an action potential.
