Central nervous system neurotransmission

"Central nervous system neurotransmission" is not a specific molecule, receptor, or protein but rather refers to the overall process by which neurons in the central nervous system (CNS) communicate with each other using chemical messengers called neurotransmitters. This process involves a wide variety of molecules—including amino acids (e.g., glutamate, GABA), monoamines (e.g., dopamine, serotonin), peptides (e.g., substance P), purines (e.g., ATP), and others—that are released from presynaptic neurons and bind to specific receptors on postsynaptic cells to modulate neuronal activity[1][3][4][5]. The term encompasses multiple molecular targets such as receptors, transporters, enzymes involved in synthesis and degradation of neurotransmitters, and ion channels. Because it is not a single defined target but an umbrella term for many different molecular systems within the CNS, "central nervous system neurotransmission" should not be considered a canonical therapeutic target itself; instead, individual components of this process—such as "gamma-aminobutyric acid type A receptor," "dopamine transporter," or "acetylcholinesterase"—are valid drug targets[1][3][4]. There is something incorrect with this entry because it lacks specificity; it does not refer to any one molecule or receptor but rather describes an entire physiological process involving numerous distinct targets.
