It takes nerves for flies to keep a level head

puting power. He continues:

"Anyone who has watched one fly chasing another at incredibly high speed, without crashing or bumping into anything, can appreciate the high-end flight performance of these animals.

"They manage even though they see the world in poor definition: their version of the world is like a heavily pixelated photo compared with human vision. However, they do have one major advantage. They can update and process visual information more than ten times faster than humans, which is vital for an insect that relies on fast sensory feedback to maintain its agility."

Dr Krapp adds: "Keeping the head level and gaze steady is a fundamental task for all animals that rely on vision to help control their movements. Understanding the underlying principles in simple model systems like flies could give us useful leads on how more complex creatures achieve similar tasks."
