Wiki helped but its not authoritative. Some place it says that the fastest is 110 m/s and other place it is 120 m/s. While slowest one varies between 7 m/s (in Rana frog) to 0.5 m/s (Nociceptors) on Wiki.

Neuron action potentials: The creation of a brain signal

WebSep 6, 2024 · The movement of these ions creates an electrical current that travels down the axon. As the action potential travels down the axon, it causes ion channels to open and … WebAn action potential is part of the process that occurs when a neuron fires. During the action potential, part of the neural membrane opens to allow positively charged ions to enter the cell and negatively charged ions to exit. When the charge reaches +40 mv, the impulse propagates in the nerve fiber. What is another name for resting potential? rap vortrag https://crown-associates.com
