Thomas Willis – The Father of Neurology and Cerebri Anatome

An MVP version of Chapter 15 Volume 1 of the Neuroscience Edition

The 17th century scientific revolution produced Thomas Willis (1621–1675), English anatomist and physician often called “Father of Neurology.” His Cerebri Anatome (1664), with illustrations by Christopher Wren, provided the most detailed brain study to date. Willis mapped cranial nerves, described the “circle of Willis” arterial ring, and localized functions—advancing neurological understanding significantly.

Picture Oxford 1660s: Willis dissects brains, injects dye into arteries, revealing basal ring—ensuring blood flow despite blockage. Naming it “circle of Willis,” he highlights redundancy protecting brain.

Born Wiltshire, Willis studied Oxford, served Royalists in Civil War, built practice. His “Oxford Circle”—Boyle, Hooke, Wren—pioneered science.

Cerebri Anatome, dedicated to Archbishop Sheldon, featured Wren’s drawings—brain from below showing nerves, arteries. Willis numbered cranial nerves I–XI, described olfactory, optic, facial.

Willis localized: cerebellum involuntary movement, corpus striatum sensation, cortex memory/imagination. Described epilepsy, headaches, apoplexy—early clinical neurology.

Willis’s method: dissection, dye injection—advanced anatomy.

Uplifting cases: paralyzed patients recovering through rest—early rehabilitation insight.

Willis coined “neurology,” advanced chemistry (urine analysis diabetes). Legacy: circle of Willis standard, cranial numbering foundation.

As we approach 18th century, Willis highlights detailed mapping—foundation for brain adaptability understanding.
