Question

Quizplus · Accepted Answer

The process by which some neurotransmitters in the synapse return to the axon terminals of the neuron that released them is called reuptake. This is a common mechanism for neurotransmitter removal from the synapse, where they are taken back up into the presynaptic neuron and can be used again in future signaling processes. Neuromodulation refers to the process by which neuromodulators modify the efficacy of neurotransmission, while neuroregeneration refers to the regrowth and repair of damaged nerve tissue.
