The process associated with a decrease in the likelihood of an action potential is called:
A)depolarization
B)hyperpolarization
C)reuptake of neurotransmitters
D)underproduction of acetylcholine

Question

Quizplus · Accepted Answer

Hyperpolarization is the process associated with an increase in the negative charge within a neuron, which makes it less likely to fire an action potential. This occurs when potassium ions leave the cell or chloride ions enter the cell, making the inside more negative. Depolarization, on the other hand, is when the inside of the cell becomes more positive, increasing the likelihood of an action potential. Reuptake of neurotransmitters and underproduction of acetylcholine are not directly related to the decrease in the likelihood of an action potential.
