Evolution and Neurobiology of Biosonar Systems

Our lab studies the ecology, behavior and neurobiology of bats because of their biosonar capabilities, their gregarious social behaviors, and elaborate communication repertoire.  Bat biosonar systems are a good example of how biological systems can offer valuable insights towards improving technologies that help people, so we study how bats are adapted to perform sonar under a wide variety of environmental conditions and social contexts.

Auditory Neuroscience

Echolocation provides an exciting model system for exploring how auditory brain pathways evolved to encode the acoustic environment.  The bat’s auditory system is finely tuned to the sound of their own echoes, producing a dynamic map of the acoustic scene that is updated on a millisecond time scale.  Our neural studies investigate the cortical networks that encode auditory objects based on sonar echoes.  Our behavioral studies of investigate how bats optimize their sonar performance to detect and discriminate targets and obstacles in noisy cluttered environments.  This research has direct relevance to man-made sonar and wireless communications systems.

Graduate student opportunities

Students interested in pursuing auditory neuroscience and the neuroethology of communication are encouraged to apply to our graduate training programs in Biology, Neuroscience or Ecology and Evolutionary Biology. Contact Dr. Smotherman directly for more information.
