10-Minute Neuroscience: Action Potentials

In this video, I cover the basics of the action potential beginning with an explanation of membrane potential and how it sets the stage for the action potential. Then, I describe how an action potential is generated and how it ends. I cover the propagation of an action potential down the axon and the role myelin plays in this process. Finally, I discuss the absolute and relative refractory periods and what they mean for repeated action potential firing.

BIZARRE

This book shows a whole other side of how brains work by examining the most unusual behavior to emerge from the human brain. In it, you'll meet a woman who is afraid to take a shower because she fears her body will slip down the drain, a man who is convinced he is a cat, a woman who compulsively snacks on cigarette ashes, and many other unusual cases. As uncommon as they are, each of these cases has something important to teach us about everyday brain function.

A unique combination of storytelling and scientific explanation that appeals to the brain novice, the trained neuroscientist, and everyone in between. Dingman explores some of the most fascinating and mysterious expressions of human behavior in a style that is case study, dramatic novel, and introductory textbook all rolled into one. - Alison Kreisler, PhD, Neuroscience Instructor, California State University, San Marcos
