In these two videos, I discuss membrane potential and the action potential. Membrane potential refers to the difference in charge between the inside and outside of a neuron, which is created due to the unequal distribution of ions on both sides of the cell. The term action potential refers to the electrical signaling that occurs within neurons. This electrical signaling leads the release of neurotransmitters, and therefore is important to the chemical communication that occurs between neurons. Thus, understanding the action potential is important to understanding how neurons communicate.
Welcome to Neuroscientifically Challenged! All of the content for the site is collected on this home page, but if you're looking for specific types of content you can use the menu bar above. By clicking on Articles, you'll find links to blog articles on a variety of different neuroscience topics. The Know Your Brain link will take you to a listing of reference articles, each of which deals with a different part of the nervous system. Clicking on the 2-Minute Neuroscience Videos link will take you to an assortment of 2-minute videos that each teach you about a different aspect of neuroscience. And the Glossary contains a large selection of definitions for common neuroscience terms.
