Scientists Use Ultrasound to Jump-start a Man’s Brain After Coma
A 25-year-old man recovering from a coma has made remarkable progress following a treatment at UCLA to jump-start his brain using ultrasound. The technique uses sonic stimulation to excite the neurons in the thalamus, an egg-shaped structure that serves as the brain’s central hub for processing information.
“It’s almost as if we were jump-starting the neurons back into function,” said Martin Monti, the study’s lead author and a UCLA associate professor of psychology and neurosurgery. “Until now, the only way to achieve this was a risky surgical procedure known as deep brain stimulation, in which electrodes are implanted directly inside the thalamus,” he said. “Our approach directly targets the thalamus but is noninvasive.”
Monti said the researchers expected the positive result, but he cautioned that the procedure requires further study on additional patients before they determine whether it could be used consistently to help other people recovering from comas.
“It is possible that we were just very lucky and happened to have stimulated the patient just as he was spontaneously recovering,” Monti said.
A report on the treatment is published in the journal Brain Stimulation. This is the first time the approach has been used to treat severe brain injury… Read More>>
