My laboratory is interested in the neural mechanisms of behavior. We are interested in how fish detect, integrate and respond to external cues in the environment. To achieve this goals, we have developed an implantable electrode and telemetry system to record physiological signals from free swimming fish.

The majority of the research has focused on the marine teleost, Opsanus tau. This work is conducted at the Marine Biological Laboratory in Woods Hole, MA during the summer months. In addition to neurophysiology, we also conduct ecological, behavioral and mariculture studies. During the academic year, Dr. Mensinger’s graduate students are investigating lateral line sensitivity in catfish, optic nerve regeneration in sunfish and competitive interactions between native and exotic fish. Dedicated undergraduate students are encouraged to contact the laboratory about research opportunities.

Research

My main interest is the neural mechanism of behavior. The lab spends the academic year working with freshwater fish and then travels to the Marine Biological Lab in Woods Hole, MA to continue our long standing toadfish projects. Although neurophysiology is the main focus of the lab, you will find both graduate and undergraduate students pursuing a wide variety of projects such as nerve regeneration, predator prey interactions and aquaculture.
