Coma patient's brain jump-started by ultrasound
UCLA doctors have "jump-started" a 25-year-old coma patient's brain using low-intensity focused ultrasound pulsation. Initially, the patient showed a conscious response when the doctors roused neurons in his thalamus, but after few days, he was fully awake. The team claimed a portable low-cost device could be developed to help recover coma patients if the treatment works in future trials.
