What is the refractory period in neurons?
A period of time during which a neuron cannot generate another action potential
A period of time during which a neuron is able to generate multiple action potentials
A period of time during which a neuron is resting and not conducting any electrical impulses
A period of time during which a neuron is repairing its cell membrane
The refractory period is a period of time following an action potential during which a neuron is unable to generate another action potential, no matter how strong the stimulus. This is due to the inactivation of voltage-gated sodium channels and the slow opening and closing of potassium channels.
Option a is the correct answer.
