This focus on neuroscience isn't new – back in 1990, US President George W. Bush designated the 1990s the “Decade of the Brain” with a series of public awareness publications and events. Since then interest and investment in neuroscience has only grown more intense; some have even spoken of the twenty-first century as the “Century of the Brain.”
