Inhibitory local potential

Author: wfhb

August undefined, 2024

Graded potentials that make the membrane potential more negative, and make the postsynaptic cell less likely to have an action potential, are called inhibitory post synaptic potentials (IPSPs). Hyperpolarization of membranes is caused by influx of Cl or efflux of K . As with EPSPs, the amplitude of the IPSP is directly proportional to the number of synaptic vesicles that were released.
