Brain tunes itself to criticality, maximizing information processing
New research from Washington University in St. Louis confirms that the brain tunes itself to a point where it is as excitable as it can be without tipping into disorder, similar to a phase transition. The new research from Keith Hengen, assistant professor of biology in Arts & Sciences, is published Oct. 7 in the…
