Some predatory insects see ten times faster than humans. A fruit fly, when compared to a human, has a visual system that is five times faster. Prior to this, being able to determine how a brain responds to color was limited to humans and animals with slower visual systems. Through the development of new technology, University of Minnesota researchers have developed a method that allows scientists to understand how a fruit fly’s brain responds to seeing color. Summary: Novel technology allows researchers to understand how a fruit fly’s brain processes color.
