During the relative refractory period, the membrane is hyperpolarized and a larger incoming stimulus is required to trigger an action poential. How does this affect the response properties of a sensory neuron?.



Answer :

The pace at which the sensory neuron emits action potentials will rise with increased input intensity.

How can hyperpolarization of a membrane affect it?

A cell's membrane potential changes during hyperpolarization to become more negatively charged. It is a depolarization's opposite. By requiring more stimuli to raise the membrane potential to the action potential threshold, it prevents action potentials.

Some potassium channels remain open throughout the hyperpolarization period, whereas sodium channels reset. Before the potassium channels shut, there is a period of enhanced potassium permeability, which causes an excessive potassium outflow. This leads to hyperpolarization, which is seen by the tiny drop that follows the spike.

The membrane potential becomes marginally more positive than its resting value as a result of the increased outflow of potassium ions.
