Back in 1999, I wrote a Boing Boing Digital article called "Head Like A Hole," about trepanation, the intentional drilling of a hole in your skull for medical reasons or, according to its contemporary DIY practitioners, to achieve higher consciousness. But while trepanation has been around since ancient times, Katherine Foxhall argues that the commonly-held belief that the procedure was once used to cure migraines is just a myth. From Smithsonian:

In 1902, the Journal of Mental Science published a lecture by Sir Thomas Lauder Brunton, a London physician well-known for his work on pharmacology and ideas about migraine pathology. The lecture mixed neurological theory and armchair anthropology, and ranged over subjects including premonitions, telepathy, hypnotism, hallucinations, and epileptic and migrainous aura. In one notable passage, Brunton proposed that visions of fairies and the sound of their jingling bells were “nothing more” than the zigzags of migraine aura, and the aural results of nerve centre stimulation.

Brunton proposed that openings bored into ancient Stone Age skulls during life had been made to cure migraine. His suggestion followed considerable excitement during the 1870s when the French physician and anthropologist Paul Broca claimed that ancient skulls discovered in Peru and France had not only been opened surgically during life in order to release evil spirits, but that the patients had survived. To Brunton, it seemed obvious that the holes would have been made at the request of migraine sufferers in order to “let the headache out”.
