CrawFly Invertebrate Neurophysiology Course


ADInstruments and the Department of Neurobiology and Behavior at Cornell University will co-host a 5 day hands-on workshop for higher education life science instructors seeking to expand their curriculum reach in the neurosciences.

The training event will be based on topics explored in the “Crawdad Project,” a three-year program funded by the National Science Foundation to promote the use of invertebrates in undergraduate physiology and neuroscience lab courses. The goals of this hosted workshop are to provide teachers hands-on experience with invertebrate preparations that demonstrate basic principles of nervous system physiology, and can easily be incorporated into laboratory courses back home.
