A Computational Cognitive and Visual Neuroscience Laboratory

PI: David J. Freedman, Ph.D.

Through experience, we learn to interpret the sights and sounds around us and to make decisions that move us closer to achieving our goals. Our ability to learn from and adapt to our ever changing environment is a foundation of complex behavior, as it allows us to make sense of incoming sensory stimuli and to plan successful actions. To study these questions, our laboratory uses advanced neurophysiological and behavioral techniques, in parallel with machine learning approaches for studying cognitive computations in artificial neural networks.  Together, our work is providing insights into the brain mechanisms of visual learning, recognition and decision making.
