Give examples of excitatory neurotransmitters and inhibitory ones.
Answer:
E--Acetylcholine, Glutamate, Seratonine
I---GABA, Glycine
Neurotransmitters are natural. But drugs can be made to produce these responses. Eg. Valium is an inhibitory one. Cuases hyperpolarization so AP signal needs to be even stronger for the impulse to propagate (hence less pain felt)
