π§ Scientists Found the Brain Rhythm Behind Why Parkinson's Implants Work
For over 25 years, deep brain stimulation has eased tremors and rigidity in Parkinson's patients β but nobody could say exactly why. A new study from researchers at Harvard, CharitΓ© Berlin, and universities in Cologne and DΓΌsseldorf has pinpointed a specific brain network communicating in a "high beta" electrical rhythm (20β35 Hz) as the key driver of the therapy. The discovery could let doctors fine-tune stimulation settings far more precisely, especially for patients who haven't responded well. Could targeting this specific rhythm finally crack open the treatment for everyone?
