Is Your Brain Really Necessary?
The reason for the apparently absurd question in the title is the remarkable research conducted at the University of Sheffield by neurology professor the late Dr. John Lorber. When Sheffield's campus doctor was treating one of the mathematics students for a minor ailment, he noticed that the student's head was a little larger than normal. The doctor referred the student to professor Lorber for further examination. The student in question was academically bright, had a reported IQ of 126 and was expected to graduate. When he was examined by CAT-scan, however, Lorber discovered that he had virtually no brain at all. Instead of two hemispheres filling the cranial cavity, some 4.5 centimetres deep, the student had less than 1 millimetre of cerebral tissue covering the top of his spinal column. The student was suffering from hydrocephalus, the condition in which the cerebrospinal fluid, instead of circulating around the brain and entering the bloodstream, becomes dammed up inside. Normally, the condition is fatal in the first months of childhood. Even where an individual survives he or she is usually seriously handicapped. Somehow, though, the Sheffield student had lived a perfectly normal life and went on to gain an honours degree in mathematics. Professor Lorber (who was a member of the committee sitting to decide who should be awarded the Nobel Prize) identified several hundred people who have very small cerebral hemispheres but who appear to be normal intelligent individuals. Some of them he describes as having 'no detectable brain', yet they have scored up to 120 on IQ tests. No-one knows how people with 'no detectable brain' are able to function at all, let alone to graduate in mathematics, but there are a couple theories. One idea is that there is such a high level of redundancy of function in the normal brain that what little remains is able to learn to deputise for the missing hemispheres. Another, similar, suggestion is the old idea that we only use a small percentage of our brains anyway - perhaps as little as 10 per cent. The trouble with these ideas is that more recent research seems to contradict them. The functions of the brain have been mapped comprehensively and although there is some redundancy there is also a high degree of specialisation - the motor area and the visual cortex being highly specific for instance. Similarly, the idea that we 'only use 10 per cent of our brain' is a misunderstanding dating from research in the 1930s in which the functions of large areas of the cortex could not be determined and were dubbed 'silent', when in fact they are linked with important functions like speech and abstract thinking. The other interesting thing about Lorber's findings is that they remind us of the mystery of memory. At first it was thought that memory would have some physical substrate in the brain, like the memory chips in a PC. But extensive investigation of the brain has turned up the surprising fact that memory is not located in any one area or in a specific substrate. As one eminent neurologist put it, 'memory is everywhere in the brain and nowhere.' But if the brain is not a mechanism for classifying and storing experiences and analysing them to enable us to live our lives then what on earth is the brain for? And where is the seat of human intelligence? Where is the mind? Lorber's discovery is far from isolated. In researching my book 'Alternative Science' I found literally scores of such cases of scientific discoveries that are well-attested with strong direct laboratory evidence, and yet are ignored by conventional science. Many more such examples are also given on the Alternative Science Website.

Space Probes Speed Up Recently scientists were amazed that the space probes now leaving our solar system suddenly started to speed up? They should not be surprised because the gravity from the sun pulls in material from around our solar system and then compacts it. Just like our atmosphere is more concentrated closer in. Earthquake and Disaster Delays in Scientific Innovation In our present period we are continually reminded that we live on the surface of the planet and with that great honor comes issues of Mother Nature we must deal with. It is a fair trade off, as you get sunshine, warmth and heat from the sun; water, fish and surfing opportunities from the ocean and the stars, moon and cosmos to propel thought, enlightenment and understanding of who we are and perhaps some insight into why we are here. God Created Man, 5000 years ago? Well it is written that God created man 5000 years ago, there can be no doubt about it. The Holy scripture guarantees that is in fact how it exactly happened? Oh really? So how do you explain the fossil record, life on mars and dinosaur bones? Oh, you cannot explain that? I see, but you still wish to debate the works in the various religions and completely factual and to be followed literally then? Hmm? Okay, then I have a book that, I personally recommend that you do not read:"The Seven Daughters of Eve" By Bryan Sykes. Why Dont Moths Fly to the Moon? Surely, in the days before man invented artificial light, moths would have been attracted to the only light source at night - the moon. Wouldn't they have just kept on flying until they dropped from exhaustion? In fact does this not happen today in sparsely populated areas, where the moon is still the only night-light available?Navigation Sorry to disappoint you, but there is no concrete answer - only theories. Small Attack Submarines, Which Turn Into Hydrofoils and Fly We propose single man underwater vehicles (attack submarines), which have inflatable Airbags using CO2 cartridges for rapid ascent. The design of these vehicles will encompass bended material, which makes rings underneath resembling typical designs of small hydrofoils. Creation CREATION OF ANIMATE FROM INANIMATE: - We have touched upon some scientific dry wells and frauds already.

Secrets of The Mathematical Symmetry of Nature and Patterns of Erosion As scientists and theorists study patterns, design, chaos, complexity they often turn to nature for examples and there is plenty of examples in nature too.

Hibernate Enemy with Gas Cloud Scientists have discovered chemicals, which cause humans to go into a hibernation type state similar to our mammal cousins the bear.
