WebThe local field potential is believed to represent the sum of synaptic inputs into the … WebInhibitory Postsynaptic Potential (IPSP) Term. Describe in detail the difference between EPSP and an IPSP. Definition. EPSP are graded potentials that can initiate an AP in the axon, whereas IPSPs produce a graded potential that lessens the chance of an AP in an axon. EPSP-small depolarization is created; IPSP-small hyperpolarization is created.
