Today in "biology is endlessly fascinating:"
Dickinson says that LED panels are often used with fly experiments because the insects have the fastest visual systems on the planet and can distinguish individual flickers of light up to about 200 times each second. By comparison, most video is shot at 24 frames per second. “A fly would see that as a slideshow,” Dickinson says.
Just imagine how much effort and money had to be put in to make the fly that lights up whenever it uses its muscles. Holy smokes, that is a huge experiment even before you figure out how they fly!
