Detecting the direction of motion is one of the most important and basic tasks of any visual system. In the fly, this computation is described in amazing detail by a specific model, the so-called 'Reichardt Detector'. Here, the various processing steps underlying motion detection are specified in purely algorithmic terms, i.e. temporal filtering, multiplication, subtraction. However, neither the neurons performing these processing steps nor the underlying biophysical mechanism have been discovered despite intensive research for almost half a century. Finding the neural implementation of the Reichardt detector has therefore become the 'Holy Grail' of fly motion vision. I will present recent progress made along this way, largely owed to the combination of genetic and electrophysiological methods in the fruit fly Drosophila.
