Complete the following statements to assess the understanding of how drugs increase the effect of a neurotransmitter at a synapse. Not all choices will be used. Most illicit drugs affect the nervous system by affecting the action of a particular neurotransmitter at in the brain. Drugs that increase the likelihood of neuron excitation are called , and those that decrease that likelihood are called .
Specific ways that a drug could increase the effect of a neurotransmitter (NT) at a synapse include 1) causing the NT to leak out of a synaptic into the synaptic cleft; 2) preventing of the NT presynaptic membrane; and, 3)blocking an that normally breaks down the NT.
