Neurotransmission
Neurotransmission is the process by which neurons communicate with one another and with target cells through the controlled release and reception of chemical messengers called neurotransmitters.
Overview
When an action potential reaches the axon terminal, it triggers neurotransmitter release into the synaptic cleft, where molecules bind to postsynaptic receptors and excite or inhibit the target cell before being cleared by reuptake, enzymatic degradation, or diffusion. Disruptions in systems involving dopamine, serotonin, acetylcholine, glutamate, and GABA are directly implicated in Parkinson's disease, depression, schizophrenia, epilepsy, and Alzheimer's disease.
Why it matters
Understanding neurotransmission has been transformative for medicine, enabling the rational design of psychopharmacological agents that target specific receptors or reuptake transporters and reshaping treatment of mental health and neurological disorders. It is the fundamental mechanism underlying every thought, emotion, sensation, and voluntary movement.
