Research Interests: Neurobiology of Sensory Systems Our research focuses on the neurobiology of sensory information processing, using two model systems: sound localization in echolocating bats, and orientation to touch in naturally blind naked mole-rats. We combine behavioral and physiological techniques to study these highly adapted systems, and to examine fundamental questions about sensory organization and behavior.
In many cases, progress in understanding sensory behavior and neural processing has been aided by the analysis of model systems. Echolocating bats are considered to be hearing specialists. They rely on hearing the echoes from their own calls to navigate though their environment, and to identify and localize the flying insects that they prey upon. In my lab, we study the behavior and neural information processing associated with sound localization.
In contrast to bats, the naked mole-rat, a totally subterranean animal, does not localize sounds well, nor is it able to use visual information. Rather, these animals place a great emphasis on touch for gathering and processing spatial information. Our focus with the naked mole-rats is on their “body whiskers,” a unique array of sensory hairs that criss-crosses their otherwise furless bodies, and functions in guiding orientation behaviors.
