Nature - Fruit fly uses calculus, or something like in its mental calculation. Oh, the Math co-processor is in its wings

It is not just the discovery, I was also amazed at the techniques used by scientists in the experiment.

According to the article:- 

Neurons near the wings, part of what is called the haltere circuit, do the computations and send signals to the wings to correct the problem.

 The wings of fruit flies beat about 250 times a second.Disturb a fly’s flight in an extreme way, Dr. Cohen said, and “within three wing beats that sucker has recovered completely.”
