Flatau’s law—“the greater the length of the fibers in the spinal cord the closer they are situated to the periphery”.

In Nothnagel’s Handbuch der speziellen Pathologie und Therapie, XI, Bd. 3, Abt. 3-4.

Flatau presented the full clinical picture of migraine and described the disease as an innate disposition to pathological metabolic processes in the nervous system. He described its distinguished characters - ocular, epileptic, mental and facial. The book was based on observations of himself and about 500 cases from his own practice.
