Central nervous system neuron

Central nervous system neurons are the primary functional cells of the brain and spinal cord, responsible for receiving, processing, and transmitting information via electrical and chemical signals. There are multiple subtypes—such as sensory neurons, motor neurons, and interneurons—each defined by their connections, neurotransmitter types, and function[1][5]. Neurons are distinguished from other CNS cell types (such as glia) by their excitable membranes, ability to fire action potentials, and role in synaptic transmission. Classification systems for neurons are complex and consider electrophysiology, morphology, and transcriptomic profiles[1][2]. In disease, neurons are implicated in a wide variety of CNS disorders, but neurons themselves are not directly drug targets; rather, their molecular components (e.g., receptors, ion channels, transporters) are the usual focus of therapeutic intervention[2][3][5]. Key caveat: "Central nervous system neuron" is not a molecular target but a category of cells; thus, it is not considered a canonical therapeutic target, and the entry should be flagged as inappropriate/wrong for a database of molecular therapeutics. Targets should be individual molecules or well-defined proteins within these cells (e.g., "N-methyl-D-aspartate receptor" or "Voltage-gated sodium channel," not "neuron")[1][5].
