Mapping and Manipulating Neural Networks with Artificial Intelligence
Dr. Schwarz and his team develops and utilizes novel technologies that help to map and characterize neuronal circuits within the hippocampus and the olfactory system that allow behaviorally adjusted neuronal computations. The teams newest technology is an artificial intelligence-based system called DeepLabStream (DLStream) that instantly recognizes a behavioral section of mice and facilitates Cal-Light induced labeling of the underlying neural networks involved in generating this behavior.
