[Source: ScienceDaily] – The ability to diagnose and treat brain dysfunction without surgery, may rely on a new method of noninvasive brain stimulation using pulsed ultrasound developed by a team of scientists led by William “Jamie” Tyler, a neuroscientist at Arizona State University.

The approach, published in the journal Neuron on June 9, shows that pulsed ultrasound not only stimulates action potentials in intact motor cortex in mice but it also “elicits motor responses comparable to those only previously achieved with implanted electrodes and related techniques,” says Yusuf Tufail, the lead author from ASU’s School of Life Sciences.
