As a resident of Dr. Penfield, I was impressed by his clinical analysis of each patient's complex medical problem. This always included a detailed history and physical examination by the “Neuro” staff with added information gathered by Dr. Penfield during his personal interviews with each patient. This clinical information was later reinforced by extensive operative notes and hand drawn pictures by Dr. Penfield along with photographic studies of the operative site. I soon realized how important it was to collect complete documentation on each patient.
