Neurophysiology of Action Potentials

Action potentials represent the fundamental unit of communication within the nervous system. These electrical impulses are vital for transmitting signals between neurons and across neural networks. At its core, an action potential is a rapid and transient change in the membrane potential of a neuron, characterized by the sequential opening and closing of voltage-gated ion channels. The process by which an action potential is generated and propagated along the length of a neuron is a complex and...
