Window on the Brain
Return to Scientists
The brain's electrical signals become distorted as they pass through the skull—much like light through frosted glass—impeding diagnosis of conditions such as stroke, epilepsy, and depression. Allen Malony and the Neuroinformatics Center are clearing a window to the brain by harnessing the power of parallel and grid computing technology. They map EEG data to brain activity on the cortex surface, then visualize this activity in three dimensions from scans produced in the Lewis Center for Neuroimaging.
"The breakthrough is the new ability to generate models of
the surfaces of interior brain structures. Our goal is to track
the electrical activity of the brain by achieving a full
computational model of the human head."
