The tale of the dueling neurosurgeons, di Sam Kean, che riporta le osservazioni di Daniel Gajdusek, premio nobel per la medicina per il suo lavoro sul kuru, malattia prionica

Da wiki:

Gajdusek concluded that kuru was transmitted by the ritualistic consumption of the brains of deceased relatives, which was practiced by the Fore. He then proved this hypothesis by successfully transmitting the disease to primates and demonstrating that it had an unusually long incubation period of several years.[4] He did this by drilling holes into chimps' heads and placing pureed brain matter into the cerebellum.[5][6] These animals then developed symptoms of kuru. This was the first demonstration of the infectious spread of a noninflammatory degenerative disease in humans.
