Message:


If the brain uses electrical signals to send and recieve messages why cant 
we just measure a signal, then replicate it to cause the brain to perceive 
something? Also, along the same lines, is it possible to manufacture 
artificial smell molecules? or to create artificial eyes by just sending 
the right signals?
