In neuroscience, an excitatory postsynaptic potential (EPSP) is a postsynaptic potential that makes the postsynaptic neuron more likely to fire an action potential. This temporary depolarization of postsynaptic membrane potential , caused by the flow of positively charged ions into the postsynaptic cell, is a result of opening ligand-gated ion ...
Both EPSP and IPSPs generation is contingent upon the release of neurotransmitters from a terminal button of the presynaptic neuron. The first phase of synaptic potential generation is the same for both excitatory and inhibitory potentials.
When an ion channel opens and there is a net gain of positively charged ions, like sodium (Na +) and calcium (Ca 2+), that flow into the cell, this creates excitatory postsynaptic potentials (EPSP) that depolarize the cell membrane increasing the likelihood of an action potential by bringing the neuron's potential closer to its firing threshold ...
This depolarization is called an EPSP, or an excitatory postsynaptic potential, and the hyperpolarization is called an IPSP, or an inhibitory postsynaptic potential. The only influences that neurons can have on one another are excitation, inhibition, and—through modulatory transmitters—biasing one another's excitability.
An inhibitory postsynaptic potential (IPSP) is a kind of synaptic potential that makes a postsynaptic neuron less likely to generate an action potential. [1] The opposite of an inhibitory postsynaptic potential is an excitatory postsynaptic potential (EPSP), which is a synaptic potential that makes a postsynaptic neuron more likely to generate an action potential.
