The central nervous system, information integration center of the body, is mainly composed of neurons.and glial cells. The neuron is one of the most basic and important structural and functional units of the central nervous system, with sensory stimulation and excitation conduction functions. Astrocytes.and microglia belong to the glial cell family, which is the main source of cytokines.and represents the main defense system of the central nervous system. Nerve cells undergo neurotransmission or gliotransmission, which regulates neuronal activity via the ion channels, receptors, or transporters expressed on nerve cell membranes. Ion channels, composed of large transmembrane proteins, play crucial roles in maintaining nerve cell homeos.asis. These channels.are also important for control of the membrane potential and in the secretion of neurotransmitters. A variety of cellular functions.and life activities, including functional regulation of the central nervous system, the generation and conduction of nerve excitation, the occurrence of receptor potential, heart pulsation, smooth muscle peris.alsis, skeletal muscle contraction, and hormone secretion, are closely related to ion channels.associated with passive transmembrane transport. Two types of ion channels in the central nervous system, potassium channels.and calcium channels, are closely related to various neurological disorders, including Alzheimer's dis.ase, Parkinson's dis.ase, and epilepsy. Accordingly, various drugs that can affect these ion channels have been explored deeply to provide new directions for the treatment of these neurological disorders. In this review, we focus on the functions of potassium and calcium ion channels in different nerve cells.and their involvement in neurological disorders such as Parkinson's dis.ase, Alzheimer's dis.ase, depression, epilepsy, autism, and rare disorders. We also describe several clinical drugs that target potassium or calcium channels in nerve cells.and could be u
