We all know that an image is projected on the retina. Then what? Nerves cells separate the image into different channels, and "this pre-sorted information is then transmitted to the brain as parallel image sequences," notes MedicalNewsToday. "Scientists from the Max Planck Institute of Neurobiology in Martinsried have now discovered that fruit flies process optical information in a similar way. The evidence suggests that this type of wiring is an effective energy-saving mechanism and is therefore deployed by a diverse range of animal species. (Nature, November 11, 2010)"
