Sometimes, in response to a puff of air aimed at its face, a fruit fly larva will scrunch its head back. Other times, its head will turn to the side. Why does it sometimes scrunch? Why, at other times, does it turn the other cheek? These may sound like useless questions, but top neuroscientists are fascinated by the answers. Mapping the brain circuitry of a humble fruit fly larva is a step toward understanding how neurons create connections, send signals and ultimately produce consciousness. getAbstract recommends this article to readers fascinated by the cutting edge of neuroscience.
