Stunning 3D ‘glass brain’ shows neurons firing off in real-time. The structure of the brain is mapped using magnetic resonance imaging (MRI). The user then wears cap covered with electrodes that measure differences in electric potential to record brain activity. This activity is revealed on-screen. The different colors represent the different frequencies of electrical energy in the brain, as well as the paths by which that energy moves around.
The Glass Brain can’t be used to show exactly what the user is thinking, but can paint a broad picture of brain activity. The Glass Brain is a Unity3D brain visualization that displays source activity and connectivity, inferred in real-time from high-density EEG using methods implemented in SIFT and BCILAB, developed at the Swartz Center for Computational Neuroscience, University of California, San Diego, and Syntrogi Labs.
The project was developed as a collaboration with Adam Gazzaley and the Neuroscape Lab at UC San Francisco, with contributions from NVIDIA, StudioBee, and many others.
