Unformatted text preview: Facilitate (agonize) by-chemical that mimic the effects of a nerutransmitter, rather than blocking, we can have a chemical that acts or looks just like a neurotransmitter-chemical that slows the process of reuptake, so the neurotransmitter spends a longer time in the synapse and has a stronger effect-incraseing the amount of neurotransmitter that gets released when an action potential fires anything that increases the effect of a neurotransmitter is an agonist and anything that interferes with or slows down the effect of a neruotransmitter is an antagonist...
