Mind control with sound and light – Boing Boing
Comments(0)
From a slew of new brainwave toys and bionic monkeys to advanced brain scans and wireless neuro-implants that will soon enable paralyzed people to remotely operate computers with their minds, the gap in the human-machine interface is closing. But while mind-reading gets all the glory, other researchers are developing new amazing non-drug methods to control the brain as well. We've posted many times about zapping regions of the brain with magnetic pulses, called transcranial magnetic stimulation, to treat depression, boost creativity, or even improve reaction time. And brain "pacemakers" are increasingly common treatments for epilepsy, Parkinson's, and even depression. What's next? Mind control through sound and light.
Arizona State University researchers are using ultrasound pulses to stimulate activity deep inside the brain from the outside. The sound waves cause brain cells to spew certain chemical neurotransmitters, ultimately resulting in physical movements or other effects.
