This project goal is to launch the Canadian Neurophotonics Platform. The platform will serve as a catalyst to create, validate, and disseminate neurophotonics tools, and train the wider community for their use. The mission of the Canadian Neurophotonics Platform is to: 1) Create novel tools to image, measure, and control the nervous system with light; 2) Validate these novel tools in the Early Adoption & Testing Nodes; 3) Disseminate these validated tools across the Canadian neuroscience community; 4) Optimize usage of photonics technologies in the Early Adoption & Testing Nodes; 5) Train HQPs in to use the tools for neuroscience research; 6) Maximize sharing of information and know-how across sites to stimulate emergence of innovative avenues to exploit photonics technology for neuroscience.
