Q

What is a neurotransmitter?

A

A chemical that is stored in the axon terminals of the presynaptic neuron. An electrical impulse through the neuron stimulates the release of the neurotransmitter into the synaptic cleft, which in turn determines whether another electrical impulse is generated.

Q

Reuptake is the process of what?

A

the process of neurotransmitter inactivation by which the neurotransmitter is reabsorbed into the presynaptic neuron from which it had been released.

Blocking the reuptake process therefore allows more of the neurotransmitter to be available for neurotransmission.
