Скачать или смотреть How Neurons Generate and Propagate Action Potentials

This lecture starts by explaining how and why voltage gated sodium channels open within the hillock (or initial segment) when threshold is reached. It then discusses how the action potential propagates down the axon and what the term action potential means. Next it explains how the action potentials allows for exocytosis of neurotransmitters from the axon terminal buttons and how the action potential could be passed to another neuron.
