Neuroethology of electric fish

Research Description

My research subjects are the weakly electric fishes - unusual electronic animal species that the nature has ever created. Specifically, I have focused on the brain mechanisms for electric behaviors of South American and African electric fishes. My research strategy is to combine behavioral experiments for identification of computational algorithms, and neurobiological techniques for identification of underlying neuronal mechanisms. The ultimate goal of my research is to uncover fundamental design principles of the brain using these attractive creatures.
