Hyperpolarizing stimuli
A) decrease the likelihood the neuron will fire an action potential.
B) increase the likelihood the neuron will fire an action potential.
C) increase movement of sodium ions into the neuron.
D) decrease the membrane potential.

Question

Quizplus · Accepted Answer

Hyperpolarizing stimuli refers to any stimulus that lowers the membrane potential of a neuron. This means that the inside of the neuron becomes more negative, making it more difficult for the neuron to reach the threshold for firing an action potential. Therefore, hyperpolarizing stimuli decrease the likelihood that the neuron will fire an action potential.
