SUMMARY:Undergraduate Event: Neural Circuits underlying Operant Learning in Larval Zebrafish
DESCRIPTION:<p>Florian Engert <br>Professor of Molecular and Cellular Biology</p><p>Professor Engert and his colleagues have developed an operant learning paradigm in larval zebrafish where the animal is given the ability to remove an aversive stimulus with a directed tail flick. To that end an infrared laser beam is directed at a head-fixed animal, tail-motion is recorded and analyzed online with a high speed camera and the size and direction of the motion is fed back in a closed loop system to control the power of the laser. They have found that fish learn quickly to turn off the laser with a directed tail flick in a specified direction and that they can re-learn a reversed paradigm where the learned behavior is now a tail flick towards the other direction. Whole brain 2-photon calcium imaging before, during, and after these learning blocks allows the isolation and analysis of the flexible neuronal populations that correlate and drive the learned behaviors.</p><p>Note: This event is sponsored by the Harvard Society for Mind/Brain/Behavior, and is limited to Harvard College undergraduates.</p>
