Question

Quizplus · Accepted Answer

EPSPs (Excitatory Post-Synaptic Potentials) and IPSPs (Inhibitory Post-Synaptic Potentials) are graded potentials, meaning their amplitudes vary based on the strength of the stimulus. They are not all-or-none responses, which characterize action potentials, nor are they specific to myelinated or unmyelinated axons. Their primary role is to influence the likelihood of an action potential occurring by depolarizing or hyperpolarizing the neuron, respectively.
