At first glance, Davis's research seems promising. Tetrodotoxin definitely causes paralysis and death, and researchers have documented cases in which people have recovered from near-fatal tetrodotoxin poisoning. Some of the samples Davis brought back to the United States also produced dramatic results when applied to the shaved skin of rats and a rhesus monkey. The subjects became lethargic and then immobile, but they eventually recovered completely. Other researchers, however, have raised questions about the legitimacy of Davis's research and the actual components of the samples he brought back from Haiti.
ZombieWorld by John_Deadstock A zombie is traditionally an undead person in the Caribbean spiritual belief system of voodoo . Essentially a dead body re-animated by unnatural means, the zombie creates dread among the living. Zombies have become a staple of modern horror fiction, where they usually engage in the consumption of human flesh.
An undead creature hell bent on revenge from Norse mythology. The name means ‘Ghost’ in old Norse language. The Draugr wandered about the countryside in search for its former enemies to exact revenge. They lived in the body of their former life and dwelled amongst the graveyards.
We tested the hypothesis that the parasite Toxoplasma gondii manipulates the behaviour of its intermediate rat host in order to increase its chance of being predated by cats, its feline definitive host, thereby ensuring the completion of its life cycle. Here we report that, although rats have evolved anti-predator avoidance of areas with signs of cat presence, T. gondii's manipulation appears to alter the rat's perception of cat predation risk, in some cases turning their innate aversion into an imprudent attraction. The selectivity of such behavioural changes suggests that this ubiquitous parasite subtly alters the brain of its intermediate host to enhance predation rate whilst leaving other behavioural categories and general health intact.
Origin : Haïtian beliefs and supersitions The word ' voodoo ' (vodou, vaudou, vodoun or vodun) derives from the word ' vodu ' in the Fon language of Dahomey meaning 'spirit' or 'god’ and describes the complex religious and belief system that exist in Haïti, an island of the West Indies. The foundations of voodoo were established in the seventeenth century by slaves captured primarily from the kingdom of Dahomey, which occupied parts of today's Togo, Benin, and Nigeria in West Africa, it combines features of African religion with the Roman Catholicism of the European settlers.
