Rushed to Bellevue Hospital, he was stretched out beside the artificial kidney, which was primed with two pints of blood containing heparin to prevent clotting. Attending doctors from Cornell University put a cannula into the radial artery in the patient's wrist, connected this by polyethylene tubes with the core of the artificial kidney. Key part of this core: cellophane tubing of ordinary sausage-casing size. From the core, other tubes led back to veins in the patient's elbow...
...crosses a line running across the head from ear to ear. At each junction of the ear-to-ear line and the slits in the scalp, Drs. Freeman & Watts drill a hole with a dentist's bur. The bur holes permit passage of a leucotome, or lobotomy cannula, a hollow needle through which a loop of wire can be slipped...
...forming a loop near the distal end of the instrument. The leucotome is rotated through one complete circle, cutting a sphere or core of white matter in the pre-frontal area about ten millimetres in diameter. The stylet is withdrawn a few millimetres thus replacing the loop within the cannula. A second core is cut at a depth of three centimetres and a third at two centimetres. The leucotome is then entirely removed from the brain and re-introduced in an anterolateral [front and side] direction into the same prefrontal lobe where cores are cut at a depth...
