the Hodgkin-Huxley model

The Hodgkin-Huxley model explains how nerve cells generate electrical signals, called action potentials. It describes how ions like sodium and potassium move across the nerve cell membrane through special channels, changing the electrical charge inside the cell. When a nerve cell receives a signal, these channels open and close in a specific sequence, causing a rapid electrical spike that travels along the nerve. This model helps scientists understand how nerves communicate and provides a foundation for studying the electrical activity of all neurons and muscles.
