A University of Utah researcher has found that high-frequency sound waves “can be emitted into a patient’s brain to alter his or her state.”
Basically, the sound causes the membranes around neurons to vibrate, causing the neurons to fire in the way the researchers wanted. The idea is to be able to treat patients with conditions like major depression without drugs or surgery.
This sounded like a Good Thing … but you might want to pause a moment:
The team delivered ultrasonic waves into the brain of monkeys deciding whether to look left or right. With the right frequencies and targeting the right neurons, the researchers were able to control whether the subjects chose right or left. The animals did not feel the ultrasound during the procedure.
So come November 3, if there’s someone with a strange machine near the voting booths….
