An Interactive 3D Visualization of the Brain Featuring Real-Time Brain Activity

Glass Brain is a project by Gazzaley Lab and Neuroscape Lab at the University of California, San Francisco and the Swartz Center for Computational Neuroscience at the University of California, San Diego that’s a 3D visualization of a brain with real-time brain activity pulled in via an electroencephalography (EEG) cap that can be navigated using a gamepad. This is made possible thanks to BCILAB brain-computer interface technology and the Unity game engine.

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.
