Neuroactive drugs, such as the antidepressant fluoxetine, function by affecting the metabolism of the brain. After the neurotransmitter serotonin has crossed the syrupse and attached to the post- synaptic neuron, the serotonin is normally reabsorbed by the pre-synaptic neuron. Fluoxetine inhibits the reuptake of serotonin. allowing it to remain in the synapse much longer than normal A Synapse O a. Z Ob. Y с. Х W- Fluoxetine inhibits the process above labelled...
