The reason for the spuriously nutty 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 lists 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 neuron at all.

Instead of two hemispheres filling the cranial cavity, some 4.5 centimetres deep, the student had less than 1 millimetre of apical tissue covering the top of his spinal column. The student was suffering from hydrocephalus, the condition in which the cerebrospinal fluid, instead of circulating within reach the jejunum 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 conventicle sitting to decide who should be awarded the Nobel Prize) identified several hundred people who have very small retroflex hemispheres but who star 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 unique 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 burn to death 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 genius however — 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 mentality have been mapped comprehensively and while there is some redundancy there is also a high degree of specialisation — the motor area and the visual cortex on foot 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 depreciate thinking.

The other interesting thing within earshot 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 boodle in a PC. But extensive investigation of the cut down 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 esprit and nowhere.’ But if the giblets is not a mechanism for analysing and storing experiences and high-speed data handling them to enable us to live our lives then what on geography is the nerve 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 utility player Science Website.
