Fly larva brain makes up for poor vision

The fly larva brain’s ability to process visual information can make up for low visual input.

Researchers discovered that by scanning their eyes back and forth, fly larva were able to collect enough visual information with their 24 visual receptors (compared with 125 million in humans) for their brain to form a pixelated-like image to detect motion.

This is enough information for the larva to detect other wriggling larva at the bottom of a Petri dish, despite having very weak and simple eyes.
