...doctors had handed their early diagnosis to a small, inner White House circle-Mamie Eisenhower, Assistant to the President Sherman Adams, Deputy Assistant to the President Major General Wilton ("Jerry") Persons. The diagnosis: Eisenhower had suffered an occlusion of a small branch of the middle cerebral (brain) artery on the left side; the occlusion, or blockage, might have been caused either by a small clot or a vascular spasm (see MEDICINE). In short, though the White House would not use the word, the President had suffered a stroke...
...this time Fry was ready to join forces with the State University of Iowa's Neurosurgeon Russell Meyers, who had long been convinced that the way to treat Parkinsonism was by destroying nerve bundles in two tiny parts of the brain (one on each side) called the ansa lenticularis. But he found conventional surgery too crude and damaging: it meant putting a knife through healthy tissues to get at the almost inaccessible ansa lenticularis. He saw the same objections to alcohol injections (TIME, March 21, 1955). Dr. Meyers believed that ultrasound might prove sharper and more precise than...
...skull, four by five inches. Ultrasound cannot be transmitted through bone because on meeting such resistance it generates too much heat. With the skull flap out of the way, the surgeons made a shallow pan in its place, using a metal strip as border and the dura mater (the brain's parchment-like covering) as the bottom. This they filled with salt solution from which all gas had been removed (ultrasound is transmitted best through a liquid medium...
...While the patient remained fully conscious, no more distressed than he would have been in a dentist's chair, and talked occasionally, Dr. Meyers gave the 'signal and a technician pressed a button. Ultrasound, at a frequency of 980,000 cycles per second, shot through intervening brain tissues but not in sufficient intensity to damage them. The four beams came to a sharp focus at the exact part of the ansa lenticularis on the left side (controlling right-side movements) that Dr. Meyers wanted to destroy. The ultrasound dose lasted only 1.8 seconds. The patient was moved twice...
