The visual information that a fly’s brain receives while in action is filtered in a way that eliminates potentially misleading signals. This is what a study by scientists at Rockefeller University has found by measuring electrical activity in individual neurons in their brains.
The brain has the ability to tell whether or not motion is self-generated and can cancel out information that might otherwise cause us to feel (and act) as if our surroundings were spiraling out of control. The Rockefeller team is attempting to decode this neural information in fruit flies and find out how the brain processes visual information to control behavior.
