Kestle, John R. W. | Determining the best cerebrospinal fluid shunt valve design: the pediatric valve design trial | Myriad cerebrospinal fluid shunt valve designs are available (17, IS).

Couldwell, William T. | Irving S. Cooper (1922-1985): a pioneer in functional neurosurgery | Irving S. Cooper (1922-1985), the son of a salesman, worked his way through high school, college, and medical school to become one of the pioneers in functional neurosurgery. He developed several novel techniques for the surgical management of Parkinson's disease and other crippling movement disord... | Functional neurosurgery; Cryosurgery; Dystonia; Movement disorder; Parkinson's disease; Thalamotomy; Tremor; Neurosurgical history | 1998 |
