Physics Nobel Prize winner Tony Leggett shows off his brain as Mr. January in a pinup calendar.

The 2006 calendar from the University of Illinois uses MRIs to show the brains of a dozen people who work or study at the school's Urbana-Champaign campus.

The calendar raises the profile of the school's Beckman Institute for Advanced Science and Technology says Beckman director Pierre Wiltzius.

The 2006 Big Brains on Campus calendar highlights a different brain function or ability each month.
