To answer this question, you have to do some reading toward the end of the chapter about the different effects that neurotransmitters can have.
00:08
And so a neurotransmitter is going to do one of two things.
00:11
It's either going to cause, i should say, in general it can do one of two things.
00:17
It can cause depolarization, which we would refer to as excitatory.
00:24
That means it's probably going to produce an action potential and cause something to happen.
00:29
Or it can cause hyper -polarization, which is going to stop an action potential from occurring, and we call those inhibitory.
00:41
And so this question is asking which neurotransmitter exclusively produces an inhibitory response, which would cause hyper -polarization.
00:50
So acetylcholine and norepinephrine are complicated because, they both can cause depolarization or hyperpolarization...
