Trepanation is the practice of removing a piece of the skull to expose part of the brain. It's one of the oldest known surgical procedures, dating back at least to 6500 BC. It's still practiced today, for medical reasons and also voluntarily to achieve enlightenment. Ten years ago, I wrote an article for bOING bOING Digital about Peter Halvorson, a guy who drilled a hole in his head to yield a permanent high. Peter is now the director of the International Trepanation Advocacy Group
. For even more on trepanation through the ages, check out "An illustrated history of trepanation" newly posted to the Neurophilosophy blog. From the article:
In the earliest European trepanned skulls, the holes were made by scraping the bone away with sharp stones such as flint or obsidian; later, primitive drilling tools were used to drill small holes arranged in circles, after which the piece of bone inside the circle was removed. The late Medieval period saw the introduction of mechanical drilling and sawing instruments, whose sophistication would continue to increase for several hundred years.
There is a great deal of speculation about why ancient civilizations used trepanation, as it was - and still is - carried out in the absence of head trauma. However, it is almost certain that all those who used it did so because they somehow linked the brain with behaviour. Some anthropologists suggest that trepanation was performed as part of tribal or superstitious rituals. Other researchers believe that the procedure was used as a treatment for conditions such as headaches, epilepsy, hydrocephalus and mental disorders. These were presumably attributed to possession by evil demons, such that a hole in the skull would have provided the spirits a passage for escape. Although the reasons for trepanning and the instruments used for the procedure differ with time and from culture to culture, the result is always the same: a hole in the head, usually made when the individual was fully conscious and, often, unanaesthetized.

Alex Wood is an addict but won’t give up his smartphone. But he has five strategies for limiting its control over him: “I used to wake up tired. My body would ache and my head felt sore, like waking up with a hangover. Finally, I took control, like attending an AA class for addicts, I […]
We just got the Sport model of the EPIKGO hoverboard at my office. Besides being terribly chic, it’s apparently bulletproof.
Ok, it’s not just solar powered. It’s also an anti-theft, waterproof marvel that keeps my phone’s power bar from ever getting into the red.Sure the idea seems obvious now – tuck a gigantic solar powered battery pack into an exposed slot and turn the wearer into a walking energy harvester. Simple maybe, but I didn’t […]
Thread count isn’t like one of those deceiving metrics like camera megapixels or Facebook friends—more threads are always better if you can afford them. If price was no object, we would all be snoozing soundly bundled up in 1.8 kilo-thread sheets every single night. Guess what? Price doesn’t have to be an object with this […]
Maybe it’s entirely because of podcast ads, but drag-and-drop tools like Squarespace have gotten immensely popular in recent years. While it’s definitely a great tool for any non-coders who want to get a small website up and running quickly, managing content with a primarily visual interface can become a pain once you have more than […]
