Säie: Mind phantoms

Kts. http://www.newscientist.com/news/news_224635.html Mind phantoms THERE'S nothing supernatural about ghosts, doppelgängers and out-of-body experiences, says a Swiss neuroscientist. They are simply phantom sensations like a phantom limb, he says, but spread to the whole body. People experience phantom limbs--the sense that an amputated limb is still present--when the part of the brain that normally senses the limb loses those signals (New Scientist, 17 June, p 27). Peter Brugger of the University Hospital in Zurich says that doppelgängers, in which people are aware of phantom "doubles" of themselves, have a similar origin. Some people actually see their double, often as a mirror image. This may be the result of damage to visual areas of the brain that affect the way we sense our body, says Brugger. Others merely feel the presence of a double without actually seeing one. He believes that these doubles are generated when the parietal lobes, the regions responsible for the distinction between body and surrounding space, are damaged. Out-of-body experiences, where a person "sees" their body from the outside, may be caused by temporary overactivity of certain brain regions. "Excitability of the temporal lobes seems to be a plausible explanation," says Brugger. These regions are connected to the parietal lobes and are sensitive to visual signals, low levels of oxygen and emotional arousal. Brugger believes the brain could account for other paranormal experiences: "Ghosts are probably nothing more but also nothing less than phantoms of the body."
