Neuronal cell membrane

The **neuronal cell membrane**, also known as the neuron plasma membrane, is a semipermeable lipid bilayer that encloses each neuron. It separates intracellular from extracellular environments and is embedded with various proteins—including ion channels, pumps, and neurotransmitter receptors—that regulate ionic gradients and enable electrical signal transmission. The selective permeability of this barrier underlies key processes such as action potential generation and synaptic communication. While critical for nervous system function—and implicated in diseases like multiple sclerosis when its integrity is compromised—the neuronal cell membrane itself is not considered a direct therapeutic target. Instead, drug development focuses on individual molecular components within this structure[1][2][3][4].
