About the Author

John W. Moore is a Professor Emeritus in the Department of Neurobiology at Duke University Medical Center. He earned a B.S. in Physics at Davidson College, and a Ph.D. in Physics at the University of Virginia. His work, spanning some four decades, has encompassed characterizing the ionic channels in squid axons under a variety of experimental conditions (e.g., treatment with ions, drugs, toxins, etc.), propagation of impulses in normal axons under
a variety of experimental conditions, and synaptic transmission at neuromuscular junctions.

Ann E. Stuart is a Professor in the Department of Cell and Molecular Physiology at the University of North Carolina at Chapel Hill. She earned a B.A. in Biology at Swarthmore College and a Ph.D. in Physiology at Yale University with John G. Nicholls, and has done postdoctoral work with Zach Hall and Susumu Hagiwara. The aim of Dr. Stuart's laboratory has been to understand the first stages of processing in an invertebrate visual system.

The authors wish to acknowledge the participation in this endeavor of their son, Jonathan Stuart-Moore, who contributed his skills in computer graphics and also made it possible for Neurons in Action to run on the Macintosh platform.
