The brain that changes itself is a truly amazing collection of case histories detailing the astonishing progress of people whose conditions had long been dismissed as hopeless.
The book documents the following cases:
- We see a woman born with half a brain that rewired itself to work as a whole
- A woman labeled retarded who cured her deficits with brain exercises and now cures those of others
- Blind people learning to see
- Aging brains rejuvenated
- Painful phantom limbs erased
- Stroke patients recovering their faculties
- Children with cerebral palsy learning to move more gracefully
- Entrenched depression and anxiety disappearing
One of the examples of the brain rewiring itself is of a woman with damage to the inner ear’s vestibular system, where the sense of balance resides, feels as if she is in constant free fall, like a trap door has just been opened up beneath her.
Sitting in a neuroscience lab, she puts a set of electrodes on the surface of her tongue, a wired-up hard hat on her head, and the feel of falling stops. The apparatus connects to a computer to create an external vestibular system, replacing her damaged one by sending the proper signals to her brain via her tongue.
But that’s not all. After a year of sessions with the device, she no longer needs it: her brain has rewired itself to bypass the damaged vestibular system with a new circuit.
In another case, an amputee has a bizarre itch in his missing hand: unscratchable, it torments him. A neuroscientist finds that the brain cells that once received input from the hand are now devoted to the man’s face; a good scratch on the cheek relieves the itch. Another amputee has 10 years of excruciating “phantom” pain in his missing elbow. When he puts his good arm into a box lined with mirrors he seems to recognize his missing arm, and he can finally stretch the cramped elbow out. Within a month his brain reorganizes its damaged circuits, and the illusion of the arm and its pain vanish.
