The receptor to which a neurotransmitter binds determines whether that neurotransmitter has an excitatory or inhibitory effect.

Question

Quizplus · Accepted Answer

This statement is true. The type of receptor to which a neurotransmitter binds determines whether it will cause an excitatory or inhibitory response in the receiving neuron. For example, binding to an excitatory receptor will cause a depolarization of the postsynaptic membrane, leading to an action potential, while binding to an inhibitory receptor will cause hyperpolarization and decrease the likelihood of an action potential.
