Scientists from the University of California at Los Angeles Wake a man from coma, using an ultrasonic pulse to stimulate neurons in the brain. Report on the treatment published in the journal Brain Stimulation. The study can be found on the website of the University of California.
“Until now, the only way to stimulate neurons) was a risky surgical procedure – deep brain stimulation, in which electrodes are placed directly in the region of the thalamus, – said Martin Monti, a Professor of psychology and neurosurgery at the University of California in Los Angeles, lead author of the study. – Our proposed method acts purposefully, but avoids surgical intervention.
In the course of treatment, the researchers used a device the size of a small saucer, which creates an acoustic signal, affecting some areas of the brain. The researchers switched on the device 10 times for 30 seconds. The whole process took 10 minutes. The main impact was directed at the thalamus.
As the researchers note, before the start of treatment, the patient poorly responded to external signals, but the next day his condition noticeably improved. Three days later, the patient was able to nod or negative shake my head, responding to the questions posed. According to Monti, it is necessary to conduct further research before the suggested method can be used to treat other patients.
