Professor of Organismal Biology and Anatomy at the University of Chicago, Nicholas G. Hatsopoulos, Ph.D., has long been mesmerized by space. The physical space occupied by the brain, in particular.
Hatsopoulos and his colleagues found evidence that the brain uses the spatial organization of high-frequency propagating waves of neuronal action during activity in a new study published on January 16 in Proceedings of the National Academy of Sciences.
“We focused on the high-frequency band signals given its rich information, ideal spatial reach and easiness of obtaining signal in every electrode,” said Wei Liang, first author of the study and a graduate student in the Hatsopoulos lab.
They discovered that these propagating waves, composed of the activity of hundreds of neurons, traveled in different directions across the cortical surface, founded on which direction the monkey made the joystick.
