Researchers use ultrasound to precisely and safely activate brain cells in mice

SAN DIEGO — What if you could turn any neuron in the brain on or off whenever you wanted, and for however long you wanted?
Researchers say that precise, targeted control of the brain’s circuits could be the key to treating everything from epilepsy to Parkinson’s disease to depression. And they’re already using a variety of tools to work toward that goal, from light to electricity to magnets. Some of these approaches are already being used in patients. Read the rest…
