Kestle, John R. W. | Does thalamotomy alter the course of Parkinson's disease? | Irving Cooper (3) observed that unilateral Parkinson's disease seemed less likely to progress to the other side of the body after thalamotomy that abolished contralateral tremor and rigidity, an effect that he felt might be the result of either the surgery itself or the slow progression of that par... | | 1996 |
