014 The Journey Down the Axon

In this video, Leslie Samuel explains how action potentials travel down the axon of a neuron. The video covers the structure of a neuron, focusing on the soma, axon, and axon hillock. It describes the role of voltage-gated sodium channels in generating action potentials and how sodium ions move to propagate the signal. The video also addresses why action potentials travel in one direction due to the refractory period of sodium channels. The session concludes with an invitation for viewers to ask questions.
