Brain games will make you smarter! The internet is making you dumber! Alcohol is killing your brain cells! The brain is a mystery we've been trying to solve for ages, and the desire to unlock its secrets has led to vast amounts of misinformation. Many of these false notions are more widely believed than the truth.
Almost everyone currently diagnosed with a mild form of Alzheimer's disease would be downgraded to not having the condition, if new proposed criteria for the diagnosis of cognitive problems were applied, a new study shows. Instead, people diagnosed as having "very mild" and " mild" Alzheimer's disease would be reclassified as having mild cognitive impairment (MCI), which is currently recognized as an intermittent stage between the normal loss of mental function that comes with age and the development of dementia . The new criteria broaden the definition of mild cognitive impairment, and this will cause confusion when doctors try to diagnose MCI and Alzheimer's, said study researcher Dr. John Morris, a professor of neurology at Washington University School of Medicine in St.
Could yawning be all about cooling down the brain? Err, don't people yawn because they're bored and/or tired? Yes, it's true people do yawn more at bedtime or after they've woken up and they do yawn when they're bored (people even yawn in their sleep). But yawning isn't that simple. If it was, how could you explain that some paratroopers yawn before their first jump, as do some violinists before they go on stage and Olympic athletes before their event ( Provine, 2005 ).
A shot in the head might not be such a bad thing, after all. A new study out of Harvard University came to the surprising conclusion that it may indeed be possible to trigger new cell growth in parts of the mammalian brain by injecting the brain with healthy cells, where once it had been thought impossible to repair abnormalities or damage. 1 A team of researchers working under Dr. Jeffrey Macklis transplanted fetal brain cells into the brains of mice that had a genetic defect that caused them to be obese.

A Theory on the Deja Vu or Déjà vu Phenomenon During the time while this web-page has been on the Internet, more than three thousand people (up to Nov 2009) have e-mailed to say that they have Déjà Vu experiences. That is interesting, but their descriptions have virtually always described some different phenomenon. If a person has any pre-knowledge of something that is yet to happen, like in a dream, it cannot be Déjà Vu, and is likely to be some type of Precognition. (Even if the Precognition is only a few seconds before the event.)
