Mission of "Project Tycho" is sharing MDR data. System neuroscience is often said that it has not yet reached to Kepler's era in astronomy, since there is no principle like Kepler's law that Kepler found in planetery motion. However, Kepler couldn't achieve his great work without database recorded by Tycho Brahe. This project is aiming to provide useful database for future Kepler who has wonderful idea and talent but no access to neural and behavioral data. Findings using Tycho database are expected to be shared with everyone and create positive feedback  that circulate between users.
