by McGill University Just some of the brain maps included in neuromaps. Credit: The Neuro The brain is a complex organ, and no one imaging mode can catch everything that’s going on inside it. Over the years, multiple “brain maps” have emerged, each focusing on different brain processes, from metabolism to cognitive function. While these...
COLLEGE OF ENGINEERING, CARNEGIE MELLON UNIVERSITY MRI, electroencephalography (EEG) and magnetoencephalography have long served as the tools to study brain activity, but new research from Carnegie Mellon University introduces a novel, AI-based dynamic brain imaging technology which could map out rapidly changing electrical activity in the brain with high speed, high resolution, and low cost....
