A) less likely to be in use, just through hyperpolarization of selected neurons.
B) more likely to be in use, just through depolarization of selected neurons.
C) capable of alteration, just through training and conditioning.
D) less likely to be in use, just through hyperpolarization of selected neurons and capable of alteration, just through training and conditioning.
E) more likely to be in use, just through depolarization of selected neurons and capable of alteration, just through training and conditioning.

Question

Quizplus · Accepted Answer

Presynaptic facilitation increases the release of neurotransmitters from the presynaptic neuron, making it more likely that the postsynaptic neuron will fire and the pathway will be in use. This effect can be altered through training and conditioning, making it capable of alteration. Therefore, the correct choice is E.
