WebWhat triggers the postsynaptic process? After exocytosis, neurotransmitters diffuse across the synaptic cleft and bind to specific receptors on the postsynaptic neuron, changing its permeability and generating a postsynaptic potential. What is the grand postsynaptic potential and why is it important? The output through the axon is called the Grand …

Postsynaptic potentials are changes in membrane potential that move the cell away from its resting state. For our purposes, postsynaptic potentials are measured in the dendrites and cell bodies. Ion channels that are opened by a stimulus allow brief ion flow across the membrane.

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. WebPostsynaptic potentials are changes in the membrane potential of the postsynaptic …
WebSummary: “EPSP” stands for “excitatory postsynaptic potential.”. Excitatory postsynaptic potential occurs when there is a flow of positively charged ions towards the postsynaptic cell, a momentary depolarization of postsynaptic membrane potential is created. Action potentials are also called nerve impulses or spikes.
