The new technique uses sonic stimulation to excite the neurons in the thalamus, the brain’s central hub for processing information.

DOCTORS have successfully woken up a coma patient by jump-starting his brain using a new ultrasound technique — for the first time ever.
According to The Mirror, a coffee cup size device was put against the side of the patient’s head over a 10-minute period, delivering low-intensity pulses, creating acoustic energy to stimulate brain tissue.
The procedure is known as low-intensity focused ultrasound pulsation and was first designed at the University of California by Professor Alexander Bystritsky.
The 25-year-old’s responses improved dramatically within one day and three days later he was fully conscious.

It’s possible the breakthrough could lead to the development of a helmet-like, portable device to wake coma patients.
“The changes were remarkable. It’s almost as if we were jump-starting the neurons back into function,” study lead author Dr Martin Monti, a professor of psychology and neurosurgery at UCLA, said.
“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.
“Our approach directly targets the thalamus but is non-invasive,” he added.
Researchers at UCLA plan to carry out further trials.
