Imagine that you are paralyzed. Not just your legs, not just up to your neck, but full-on paralysis. You are a helpless prisoner in your own body. Your mind is completely intact and alert, but you cannot roll over, you cannot touch your nose, you cannot move your lips, you cannot even blink on command. Without movement, your ability to communicate is nonexistent. You can perceive what is around you, but you cannot express. It’s actually a very scary thought that some people are forced to live their lives in such a helpless state.
This medical problem, known as “locked-in-syndrome”…
Some people with locked-in-syndrome can communicate by blinking or moving their eyes. Jean-Dominique Bauby wrote a book called The Diving Bell and the Butterfly by having someone sit next to him and slowly recite the alphabet. Bauby would blink his left eye when the person said the letter he needed.
But others are so locked-in they can’t even blink. A recent article in New Scientist describes a 46-year-old woman who was totally locked-in. Her doctor, Dr. Birbaumer, wanted to ask her if she’d like to have electrodes implanted in her brain to help her communicate, but they couldn’t figure out a way for the woman to answer.
As this post from the ever-interesting Mind Hacks explains, a solution came by way of an electronics store and the pH of our saliva…

Walking past an electronics store one day, Birbaumer’s colleague Barbara Wilhelm spotted a medical device for measuring the pH of saliva, and had an idea. They trained the woman to change the acidity of her spit by imagining either the taste of lemon, or the taste of milk. She learned to push the pH one way to say “yes”, the other to say “no”.
