The Ethnobiology Of Voodoo Zombification
http://scienceblogs.com/neurophilosophy/2007/09/th...
Haitian clergy attribute the creation of zombies to sorcery. The Vodun religion makes a distinction between the corps cadavre (the physical body), the gwo-bon anj (the animating principle) and the ti-bon anj (agency, awareness and memory). When zombifying someone, the Vodun sorcerer (or bokur) extracts the ti-bon anj of the victim, and retains it in an earthenware jar (where it is then referred to as zombie astral).
