Paddlefish Neurobiology

The paddlefish is a unique model to study information processing in the electrosensory system and sensori-motor integration. We study the behavior, the anatomy of electrosensory pathways in the CNS, and the physiology of electrosensory centers. For details visit the home page of the paddlefish lab.
