Mind Control With Sound and Light

researchers are developing
brain scans
and wireless
that will soon enable paralyzed people to remotely operate
computers with their minds, the gap in the human-machine interface is closing.
We’ve posted many times about zapping regions of the brain with magnetic pulses,
called transcranial magnetic stimulation, to treat depression,
, 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.
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.
other researchers are exploring how light,
can “probe” the brain
to learn about neuronal function.
