MAPPING THE BRAIN!
The human brain has billions of neurons that communicate by sending chemical and electrical signals. Mapping these electrical signals is critical to successful brain surgery and treatment of diseases like Epilepsy and Parkinson's. Researchers have developed an array of brain sensors that record electrical signals directly on the surface of the brain at a higher resolution than before, improving a surgeon's ability to remove brain tumors with minimal risk of damaging healthy tissue and to identify areas where epileptic seizures are born.
