Henry T. Wycis

Henry T. Wycis was an American neurologist who, along with Ernst A. Spiegel, pioneered stereotaxic surgery in humans during the 1940s. Stereotaxic surgery is a technique that uses three-dimensional coordinates to precisely locate and treat deep-seated lesions within the brain. This method involves immobilizing the head and using imaging techniques like X-rays or MRI to guide instruments or radiation to the target area. It is utilized for procedures such as ablation therapy for Parkinson disease, radiation therapy for tumors, and guiding biopsies. The development of stereotaxic surgery has significantly advanced neurosurgical capabilities.12
