Mastering the Mind: Brain Wave Beta Bursts and Their Role in Cognitive Control

Beta rhythms between 14-30 Hz are crucial for cognitive control, influencing how the brain processes information and could help diagnose and treat cognitive disorders. Credit: SciTechDaily.com

“Cognition depends on organizing goal-directed thought, so if you want to understand cognition, you have to understand that organization,” said co-author Earl K. Miller, Picower Professor in The Picower Institute for Learning and Memory and the Department of Brain and Cognitive Sciences at. “Beta is the range of frequencies that can control neurons at the right spatial scale to produce organized thought.

“Given the relevance of beta oscillations in cognition, we foresee a major change in the practice for biomarker identification, especially given the prominence of beta bursting in inhibitory control processes … and their importance inincluding humans, a variety of brain regions, and numerous cognitive tasks have revealed key characteristics of beta waves in the cortex, the authors write: Beta rhythms occur in quick but powerful bursts; they inhibit the power of higher frequency gamma rhythms;...

In a paper last year, Lundqvist, Herman, Miller and others cited several lines of experimental evidence to hypothesize that beta bursts implement cognitive control, essentially constraining patches of the cortex to represent the general rules of a task even as individual neurons within those patches represent the specific contents of information.

The authors acknowledge another major issue that must be resolved by further research—How do beta bursts emerge in the first place to perform their apparent role in cognitive control?
