The document summarizes plans to integrate online brain games with Facebook to increase participation and public awareness of brain research. Key points include: - An online brain game trial conducted by the BBC had 13,000 participants, demonstrating potential for mass participation. - The site aims to capitalize on this publicity by increasing users through Facebook login/sharing features while continuing research at MRC CBU. - Technical issues integrating the games with Facebook include profile image loading, permission dialogs, and caching restrictions, but usability improvements and going live involve thorough testing and backups.
