Scientists record brain activity using Bluetooth for the first time

Researchers demonstrate for the first time the ability to wirelessly record measured brain activity

patients with Parkinson's disease.This information can then be used to adjust the stimulation provided by the implanted device. Scientists note that recording deep and superficial brain activity provides a unique opportunity to peer into the underlying causes of many brain diseases. However, technological capabilities have limited direct recording of activity in controlled clinical settings.

Deep Brain Stimulation (DBS) devices are alreadyFDA approved for the treatment of Parkinson's symptoms by implanting an electrode that sends electrical signals to the brain. In 2018, an adaptive version of DBS was developed that only pushes when needed based on recorded brain activity.

“This is truly the first example of a wirelessrecording deep and superficial human brain activity over a long period of time at home, says Kari Eshmont, project leader. "This is also the first demonstration of adaptive deep brain stimulation at home."

New brain-like device mimics human learning

Another benefit of recording for long periodsperiods of time is that it is now possible to identify characteristic changes in brain activity (biomarkers) for individual patients that can predict movement disorders.

One of the benefits of this study was inthe fact that it practically did not require direct contact with doctors after surgery. The method is ideal for social distancing, which is critical during the COVID-19 pandemic.
