An improved sense of touch

The blind have a better sense of touch than those with sight because of
daily dependence on touch, not because the brain compensates for vision
loss, new research suggests. Published on Wednesday (May 11) in the
<http://dailynews.mcmaster.ca/images/Blindnesstouch.pdf> Journal of
Neuroscience, researchers at McMaster University in Ontario found that blind
participants outperform sighted individuals on all fingers, but blind
Braille readers show particular sensitivity on their reading fingers, and
both sighted and blind participants performed equally when the lips were
tested for sensitivity. "There have always been these two competing ideas
about why blind people have a better sense of touch," said author Daniel
Goldreich in a press release
<http://www.newswise.com/articles/view/576668/?sc=dwhr&xy=10000760> . "We
found that dependence on touch is a driving force here."
