Which of the following BEST describes presynaptic facilitation?
A) The modulating neuron enhances neurotransmitter release to the postsynaptic cell.
B) The modulating neuron decreases the effective communication between the cell it is modulating and its postsynaptic cell.
C) The modulating neuron triggers an action potential in the postsynaptic cell.
D) The modulating neuron stabilizes the membrane potential of the postsynaptic cell.
E) The modulating neuron causes an EPSP on the postsynaptic cell.

Question

Quizplus · Accepted Answer

Presynaptic facilitation occurs when a modulating neuron increases the release of neurotransmitter from the presynaptic neuron, thereby enhancing the communication to the postsynaptic cell. This process does not directly trigger action potentials or stabilize membrane potentials but increases the likelihood of an action potential in the postsynaptic neuron by increasing the amount of neurotransmitter released.
