Das Journal of Neurosurgery hat eine Artikelserie über Schädel-Deformationen und darunter findet sich einer über die Geschichte der modernen Trepanation, „die operative Öffnung des Schädels, entweder um operative Eingriffe im Schädelinnern vorzunehmen oder auch zur Senkung des Schädelinnendrucks, des Hirndrucks (Wikipedia).“ Unbedingt lesen, perfekte Montagslektüre!
The history of the International Trepanation Advocacy Group can be traced back to a Dutch medical student and admitted polysubstance abuser named Bart Huges, who was ultimately denied his medical degree by the University of Amsterdam at least in part for his vocal advocacy of marijuana use. During one particular episode in the early 1960s while under the influence of recreational psychoactive drugs, Huges came to believe that drilling a hole in one's head would allow blood to more freely pulse around the brain, reproducing the state of an infant's brain prior to closure of the cranial sutures. He was aware that by adulthood, the brain is denied an elastic bony covering against which to expand; in addition, he proposed that gravity gradually robbed the brain of some of its blood volume.
Trepanation, as his theory went, had the potential to reverse both of these processes. Huges felt that prolonged standing on one's head could yield the same result, albeit temporarily, but only with trepanation could a long-term so-called “permanent high” be attained. He eventually delineated his ideas in a 1962 monograph alternately entitled either Homo Sapiens Correctus, named for what he believed would describe a new species of humans with holes in their skulls, or The Mechanism of Brainbloodvolume (BBV). He later also authored the book, Trepanation: the Cure for Psychosis, and an autobiography, The Book With the Hole. Although never finishing medical school, he did in 1965 successfully self-trepan, and, based on what he felt was an excellent benefit from this procedure, later convinced others to do the same.
