This is a cross-section through the brain of Carol Vorderman - and now researchers want out why she has a head for figures. Whilst some people believe that 95% of the population can be good at sums, neurophysiologist Dr Mark Lythgoe believes that people may be born with a genetic ability for an aptitude in science, maths or art and it is not simply practice. He'll be explaining his beliefs in a series of lecture next month in London, Bristol and Glasgow sponsored by NESTA, the National Endowment for Science, Technology and the Arts, as part of its support for UK creativity and innovation and run in conjunction with the Visions of Science Photographic Awards, which are organised by Novartis, the healthcare company and The Daily Telegraph to extend interest in science. Carol is an ex-Trustee of NESTA.
