Philip Rosedale, creator of Second Life, and Adam Gazzaley, a neuroscientist at the University of California San Francisco, have developed a way for people to see each thought as it flies through the mind.  Entitled “The Glass Brain,” the project was on display at SXSW 2014 and provided attendees the opportunity to see how their brains react to assorted stimuli.

This is an anatomically-realistic 3D brain visualization depicting real-time source-localized activity (power and “effective” connectivity) from EEG (electroencephalographic) signals. Each color represents source power and connectivity in a different frequency band (theta, alpha, beta, gamma) and the golden lines are white matter anatomical fiber tracts. Estimated information transfer between brain regions is visualized as pulses of light flowing along the fiber tracts connecting the regions.
