IPSP Stands For

Question

IPSP stands for:
A) inhibitory presynaptic summation potential
B) inhibitory postsynaptic summation potential
C) inhibitory postsynaptic potential
D) inhibitory presynaptic potential
E) none of these choices

Accepted Answer

IPSP stands for "inhibitory postsynaptic potential," which is a type of synaptic potential that makes it less likely for an action potential to be generated in the postsynaptic neuron. Choice A and D both include "presynaptic," which refers to events that occur before the synapse, whereas IPSPs occur after the synapse. Choice B includes "postsynaptic summation potential," but this is not a commonly used term in neuroscience.
