BioNB222 Spring 2010 Cornell University Joseph Fetcho Lecture 04. Action Potential and Propagation I Reading Assignment Purves, D. , Augustine, G. J., Fitzpatrick, Hall, W.C. LaMantia, A.-S., McNamara, J.O. and White, L. E. (2008) Neuroscience. Sinauer Associates, Inc. Sunderland, Mass. Chapter 3. Learning Objectives: 1. To learn the parts of an action potential. 2. To learn the properties of an action potential and how each arises by changes in conductances to different ions. 3. To learn how the voltage clamp technique revealed the permeability changes to ions that underlie the action potential. Lecture Outline 1. Why action potentials? We saw earlier that recordings from neurons reveal very large, stereotypic events called action potentials. If we record from an axon of a motoneuron at different locations along the axon’s path out to muscle we would see action potentials at each location, with some delay as we move farther along the axon. Action potentials are important because passive
