When it comes to sensation, our brain seems tuned to the unexpected

On the basis of observations of how we interpret the sensation of a simple finger-tap, researchers have advanced our understanding of how the brain sorts important, externally-derived sensations, such as those created by an insect crawling on the skin, from unimportant, internally-derived sensations, such as the brush of one's own hand. The new study is reported in the June 21 issue of Current Biology by researchers Paul Bays and Daniel Wolpert of University College London and Randy Flanagan of Queen's University, Canada.
