Crawdad is a groundbreaking neurophysiology lab guide. Not just a traditional lab manual placed online, it engages students with sight and sound, teaching through video demonstration.

Updated for 2014 with higher-resolution videos and figures, new references, and updated text, the exercises are inexpensive and straightforward and have been refined for over 25 years at Cornell and other institutions. They use invertebrate preparations (primarily crayfish, but also snails and an alga), rather than classical vertebrate preparations (such as frogs, turtles, and rats) to illustrate fundamental processes of all nervous systems. The crayfish neuromuscular junction, for instance, is an excellent model for human central nervous system synapses, while snail neurons illustrate intrinsic firing properties. The use of invertebrates alleviates problems of obtaining animal care protocols. Moreover, crayfish are farmed in aquaculture, reducing the ecological impact of using frogs. In addition to guiding students to an understanding of important concepts, each exercise encourages discovery-based learning through student-designed experiments.

Crawdad contains instructions and videos, questions, suggestions for further exploration, tips for dissection and recording, calculators for equations, and background references that link directly to their journals. The text and figures are also available as PDF files. Adopting instructors also have access to additional material within Crawdad: added background information, instructions for lab setup, troubleshooting suggestions, answers to questions, and all figures and videos downloadable for classroom presentations.

NOTE: The Instructor's Package is only available to qualified instructors. For more information contact Linda VandenDolder (linda.vandendolder@sinauer.com)

Robert A. Wyttenbach joined the Emory Neuroscience and Behavioral Biology program in 2013. He completed his Ph.D. in Neurobiology and Behavior at Cornell University in 1995, and stayed on to continue his research in insect hearing and to develop teaching materials with support from the National Science Foundation. Dr. Wyttenbach has given many faculty neurophysiology teaching workshops with others on the Cornell team. He is currently developing a neurophysiology lab course at Emory and also teaches freshman and senior seminars.

Bruce R. Johnson is a Senior Research Associate and Lecturer in Neurobiology and Behavior at Cornell University, where he teaches an undergraduate lecture/laboratory course entitled Principles of Neurophysiology. He earned his Ph.D. at Boston University/Marine Biological Laboratory. His research interests address the cellular and synaptic mechanisms of motor network organization in the rat spinal cord and lobster stomatogastric ganglia, and their control by neuromodulators.

Ronald R. Hoy is a Professor in Neurobiology and Behavior at Cornell University. He earned his Ph.D. in Biology at Stanford University in 1969 with Donald Kennedy, who pioneered the use of crayfish as a model system for studying neuronal integration. His experience with crayfish in the Kennedy lab convinced him that he had found an ideal animal for teaching neurophysiology in laboratories, which he has utilized at every opportunity for the past three decades. Hoy wrote the NSF grant that supported the Crawdad Workshops for college faculty, on which the CD-ROM is based, and, along with Wyttenbach and Johnson, taught in the three NSF workshops. His research interests are in the areas of bioacoustics and animal communication, neuroethology, and evolutionary neurobiology.

The authors wish to acknowledge Dan Harris-Warrick, an undergraduate at Carleton College, for his invaluable assistance as a video editor.
