Migraine Maps

From 1870:


Frederick Lepore, an ophthalmological neurologist at Rutgers Robert Wood Johnson Medical School in New Jersey … showed Airy’s drawing to 100 of his migraine patients who experience a visual aura (only a minority do). Forty-eight of them recognized it instantly, he wrote in a historical note in the Journal of Neuro-Ophthalmology in 2014. He still shows the drawing to his patients today. “People are astonished,” he says. “They say, ‘Where did you get that?’”
