Their report being published online in PNAS Early Edition is part of a major MGH-based investigation into the mechanisms behind general anesthesia and builds on the results of a November 2012 paper.

These oscillations impair communication among brain regions. We illustrate these impressive dynamics by presenting findings from our human studies of general anesthesia using high-density EEG ...

They then applied state-of-art information theory techniques to extract brainwave patterns from the EEG data collected during the sleep study. Using AI, the researchers found that among people who ...

Get Instant Summarized Text (Gist) An AI tool analyzing EEG data from sleep can predict cognitive impairment years before symptoms appear. Subtle changes in brain wave patterns, particularly in ...
