New Variations for Strategy Set-shifting in the Rat Sho Aoki1, Andrew W. Liu1, Aya Zucca1, Stefano Zucca1, Jeffery R. Wickens1 1Neurobiology Research Unit, Okinawa Institute of Science and Technology Set-shifting, a form of behavioral flexibility, requires an attentional shift from one stimulus dimension to another. We extended an established rodent set-shifting task1 by requiring attention to different stimuli according to context. The task was combined with specific lesions to identify neuron subtypes underlying a successful shift.
C. elegans Tracking and Behavioral Measurement Jirapat Likitlersuang1, Greg Stephens2,3, Konstantine Palanski1, William S. Ryu1,4 1Donnelly Centre, University of Toronto, 2Department of Physics and Astronomy, Vrije Universiteit, 3Okinawa Institute of Science and Technology, 4Department of Physics, University of Toronto We have developed a video-rate tracking microscope system that can record and quantify C. elegans behavior at high resolution and high speeds. We have also developed computational methods to reduce the dimensionality of the worm images to a fundamental set of measurements that completely describe the shape of the worm.
