Electrical signals from the brain could help identify potential issues in the organ’s development, a new study reports. Scientists from the University of Fribourg in Switzerland and the University of Surrey investigated electrical activity in the brains of sleeping infants longitudinally, at ages 3 and 6 months. They examined three electrical signals with distinct frequencies: slow wave activity (0.75–4.25 Hz), theta (4.5–7.5 Hz) power and sigma (9.75–14.75 Hz) power, which are key markers of sleep depth and brain development.
