Definition
Neurotransmitter activity refers to the level of chemical signaling between neurons in the brain. It involves the release, reception, and reuptake of neurotransmitters, which play a crucial role in transmitting signals across synapses.
Reuptake is the process by which excess neurotransmitters are taken back up into the presynaptic neuron after they have performed their function at the synapse.
