Mechanisms of Active Sensing in Drosophila

New York University School Of Medicine
Suver, Marie

To process information about the world, the nervous system must distinguish external stimuli from internally generated sensory stimuli, but the mechanisms underlying the cellular basis of internally generated sensation and movement are not well understood. Here, Dr. Suver plans to develop a small circuit model of this process using the antennae of the fruit fly as a model system. Using electrophysiological recordings, optogenetics, and immunohistochemistry, she will develop the neural circuits controlling and sensing antennal movement as a cellular model for studying principles of active sensing. The insights gained from a tractable genetic circuit model may improve understanding of active sensation, as well as how these mechanisms might fail in disease.
