For years the centre of attention has been the cerebral hemisphere
of the brain. Researchers have looked at the left brain noting
variations in size and concentrating their efforts around the
special areas of the hemisphere in an attempt to unlock the secrets
of dyslexia. The right brain has received similar attention with
regards to dyspraxia. However, it was only with the development
of better tools for studying the brain that clues began to appear.
Over the last few years, with the advent of PET scans, and more
recently functional Magnetic Resonance Imaging, scientists began
to realise that they may have been looking in the wrong place.
