This Year, Change Your Mind

NEW Years resolutions often have to do with eating more healthfully, going to the gym more, giving up sweets, losing weightall admirable goals aimed at improving ones physical health. Most people, though, do not realize that they can strengthen their brains in a similar way.

While some areas of the brain are hard-wired from birth or early childhood, other areasespecially in the cerebral cortex, which is central to higher cognitive powers like language and thought, as well as sensory and motor functionscan be, to a remarkable extent, rewired as we grow older. In fact, the brain has an astonishing ability to rebound from damageeven from something as devastating as the loss of sight or hearing. As a physician who treats patients with neurological conditions, I see this happen all the time.

For example, one patient of mine who had been deafened by scarlet fever at the age of 9, was so adept at lip-reading that it was easy to forget she was deaf. Once, without thinking, I turned away from her as I was speaking. “I can no longer hear you,” she said sharply.

You mean you can no longer see me,” I said.

You may call it seeing,” she answered, “but I experience it as hearing.”

Lip-reading, seeing mouth movements, was immediately transformed for this patient intohearingthe sounds of speech in her mind. Her brain was converting one mode of sensation into another.
