Super-slow brain waves linked to consciousness

A distinct, periodic wave propagates across the brain every few seconds and has long been considered as an electrical “noise.” A new research suggests that these ultraslow brain waves may be directly linked to consciousness and could be critical to how the brain functions.

Marcus Raichle, a professor of medicine and of radiology, conjectures that this infraslow, undulating electrical wave might be a way to coordinate the activities of billions of neurons in all the diverse areas of the brain, writes Futurity.

These super-slow waves are different from other high-frequency brain waves but their origin and function remains largely a mystery, notes Scientific American.
