Submitted by Pendekar Timur: The brain cranks out memories near its center, in a looped wishbone of tissue called the hippocampus. But a new study suggests only a small chunk of it, called the dentate gyrus, is responsible for “episodic” memories—information that allows us to tell similar places and situations apart.The finding helps explain where déjà vu originates in the brain, and why it happens more frequently with increasing age and with brain-disease patients, said MIT neuroscientist Susumu Tonegawa. The study is detailed today in the onlineversion of the journal Science.Like a computer logging its programs’ activities, the dentate gyrus notes a situation’s pattern—it’s visual, audio, smell, time and other cues for the body’s future reference.
So what happens when its abilities are jammed?When Tonegawa and his team bred mice without a fully-functional dentate gyrus, the rodents struggled to tell the difference between two similar but different situations. “These animals normally have a distinct ability to distinguish between situations,” Tonegawa said, like humans. “But without the dentate gyrus they were very mixed up.”Déjà vu is a memory problem, Tonegawa explained, occurring when our brainsstruggle to tell the difference between two extremely similar situations. As people age, Tonegawa said déjà-vu-like confusion happens more often—and it also happens in people suffering from brain diseases like Alzheimer’s. “It’s not surprising,” he said, “when you consider the fact that there’s a loss of or damage to cells in the dentate gyrus.”

Mediation sharpens the mindThree months of intense training in a form of meditation known as "insight" in Sanskrit can sharpen a person's brain enough to help them notice details they might otherwise miss. These new findings add to a growing body of research showing that millennia-old mental disciplines can help control and improve the mind, possibly to help treat conditions such as attention deficit hyperactivity disorder (ADHD)."Certain mental characteristics that were previously regarded as relativel... The MoD and remote viewingEarlier this year (February) it was revealed through FOIA (Freedom of information act) documents that the UK MOD previously conducted secret tests into remote viewing in 2002. The MOD study concluded that even though they used complete novices with very shaky project structure and a 28% accuracy rate that 'remote viewing' was of little value. Yet this doesn’t actually seem to be the first time the British MODinvestigated remote viewing, and it seems that certain branches of the MOD actua... Paranormal - where is it ?Anthony North: A major skeptical point concerning the paranormal is that it does not seem to be needed. We have senses to offer impressions of the world, and a mind to analyse those senses. No paranormality is required.Within this system, a skeptical question would be: if paranormal powers exist, where are they? This is a valid point. Maybe the answer is that they used to be there, but are now somewhere else. Let me explain. Altered states: There is an inter-religious discipline known as mystici...

Astral Projection: Doorway to a New Dimension By Jerry Gross The concept of astral projection has been around for a long time, but until today, it has been hidden from most of humanity. Now, with the aid of astral projection, new levels of knowledge and power enable us to discover the answer to Man's eternal question about life in the physical body. Death takes on a new meaning as we begin to realize that it is only a transition to another dimension, or place of existence. By learning to astral project, we can learn many thin... Deeper look at HypnosisHypnosis is a process involving a hypnotist and a subject who agrees to be hypnotized.

Hypnosis occurs under dramatically different social settings: the showroom, the clinic, the classroom, and the police station. Showroom hypnotists usually work bars and clubs. Their subjects are usually people whose idea of a goo...
