The first human stereotaxic apparatus

Abstract
✓ The first human stereotaxic apparatus was probably built in London, England, around 1918 to the specifications of Aubrey Mussen, a neuroanatomist and neurophysiologist who had worked with Clarke. The recent acquisition by the Montreal Neurological Institute of Mussen's original apparatus prompts this report on the salient points of his career, and summary of his early contributions to stereotaxy.
