Brain waves could help predict how we respond to general anesthetics

The complex pattern of ‘chatter’ between different areas of an individual’s brain while they are awake could help doctors better track and even predict their response to general anaesthesia – and better identify the amount of anaesthetic necessary – according to new research from the University of Cambridge.

Brain Networks during the Transition to Unconsciousness
Brain networks during the transition to unconsciousness during propofol sedation (drug infusion timeline shown in red). Participants with robust networks at baseline (left panel) remained resistant to the sedative, while others showed characteristically different, weaker networks during unconsciousness (middle). All participants regained similar networks when the sedative wore off (right).
