Motional layers found in the brain: Neurobiologists discover elementary motion detectors in the fruit fly

[unable to retrieve full-text content]Recognizing movement and its direction is one of the first and most important processing steps in any visual system. By this way, nearby predators or prey can be detected and even one's own movements are controlled. More than fifty years ago, a mathematical model predicted how elementary motion detectors must be structured in the brain. However, which nerve cells perform this job and how they are actually connected remained a mystery.
