Bidirectional conduction of neural fibers

[123 ] 2. Principles of experiments

The ion concentration inside and outside the neuron cell membrane is different, and we call it a membrane potential. When the nerve cell is in a restless state, the membrane potential distribution is an external negative, that is, the rest potential; after a part of the neural cell is stimulated, the sodium ion flows into the cell, forming an external negative The action potential makes the potential difference between the excitatory zone and the rest zone and is accompanied by a partial current, and is conducted on both sides in the form of a partial current.
