When neurotransmitters communicate an inhibitory message to the postsynaptic neuron:
A) reuptake is inhibited.
B) the presynaptic neuron is less likely to activate.
C) the action potential is canceled out.
D) the postsynaptic neuron is less likely to activate.

Question

Quizplus · Accepted Answer

When neurotransmitters communicate an inhibitory message to the postsynaptic neuron, it reduces the likelihood of the postsynaptic neuron to activate. This happens because the inhibitory message makes the postsynaptic neuron's membrane potential more negative or hyperpolarized, making it less likely to reach the threshold for an action potential.
