Scientists from the University of California at Los Angeles have awakened from the coma man using ultrasound pulse stimulation of neurons in the brain. Report on the treatment published in the journal Brain Stimulation. . From the study can be found at the University of California, and briefly about the results reports RNS

«Until now, the only way (to stimulate neurons) was a risky surgery – deep brain stimulation, in which the electrodes are mounted directly to the thalamus, – said Martin Monti, a professor of psychology and neurosurgery, University of California at Los Angeles, lead author of the study. – Offers us a way to act purposefully, but allows you to avoid surgery. ”

In the course of treatment the researchers used a device the size of a small saucer, which produces an acoustic signal, working on some areas of the brain. The researchers included the device 10 times in 30 seconds. The whole procedure took 10 minutes. The main impact has been directed at the thalamus.

As the researchers note, before the start of treatment, the patient responded poorly to external signals, but the next day his condition improved markedly. Three days later, the patient was able to nod or shake my head, answering the questions posed. According to Monti, further research is needed before the proposed method can be used to treat other patients
