Reuptake

The reabsorption of a neurotransmitter by the neuron that released it.

The reabsorption of released neurotransmitter into the presynaptic neuron, allowing it to be recycled.

Some are taken back into the presynaptic neuron by reuptake, allowing them to be recycled and used again. Others are broken down by enzymes. Clearance prevents the same released neurotransmitter from continuing to affect the postsynaptic neuron indefinitely and allows separate messages to be transmitted.

The reabsorption of a released neurotransmitter into the nerve cell that released it.

Distinguish blocking receptors from blocking reuptake: antipsychotics reduce dopamine’s action at receptors, whereas SSRIs keep serotonin available in the synaptic gap for longer.

After release, some neurotransmitter can be taken back into the presynaptic neuron. This is called reuptake. Drugs can alter communication by changing whether neurotransmitters bind to receptors or how quickly they are removed from the gap.
