Scary Thought: Scientists build an ‘off switch’ for the brain
Saturday, May 3, 2014 15:18
% of readers think this story is Fact. Add your two cents.
Scientists have developed an “off-switch” for the brain to effectively shut down neural activity using light pulses.
In 2005, Stanford scientist Karl Deisseroth discovered how to switch individual brain cells on and off by using light in a technique he dubbed ’optogenetics’.
Research teams around the world have since used this technique to study brain cells, heart cells, stem cells and others regulated by electrical signals.
However, light-sensitive proteins were efficient at switching cells on but proved less effective at turning them off.
Now, after almost a decade of research, scientists have been able to shut down the neurons as well as activate them …. http://www.independent.co.uk
