Los Angeles: For the first time in the history of modern medicine a coma patient regained complete consciousness by stimulating his brain with ultrasound waves.
A UCLA team simulated a specific area of the brain, in this case the Thalamus region by focusing acoustic energy on to it, these waves are less intense than the normal ultrasound wave.
After three days of stimulation with low intensity ultrasound waves the patient got better and was able to reply in yes or no.
According to experts if this procedure is applied to other patients it will provide a new way to to treat coma patients.
Another type of procedure is done to treat coma patients, it involves putting electrodes on the Thalamus region of the brain and sending electrical signals, but this can be very dangerous.
