Research #1: Brain Mapping

Recently researchers Michael Merzenich and colleagues were able to induce cerebral palsy–like symptoms in the hindlegs of rats. They did so by tying the two hind legs together at the time the rats were born so they always moved the two legs together as one. After a while, when the restrictions on the legs were removed, the rats continued moving them together as if they had only one leg, just like Kassi. Their brains had mapped the legs as one, not as two: Merzenich and his team at the University of California San Francisco show the importance of what he terms randomized movements, what we term random movement.

Research #2: Movement with Attention

Research shows that movement done automatically creates little or no new connections in the brain: “[T]he variable determining whether or not the brain changes is . . . the attentional state of the animal.”

In experiments with owl monkeys Merzenich’s group demonstrated a clear correlation between the power of attention (to the feeling of the movement being done) and the brain’s ability to change itself:
