The fly visual system, although tiny when compared to the mammalian visual system, can still perform highly sophisticated spatial tasks like collision avoidance, landing on objects, pursuit of prey, etc. Flies outperform human-made autonomous flying systems in solving such spatial tasks by a long way. This is partly due to their ability to perceive and respond to optical flow generated by motion in...
In nature, it is an important task for animals to detect small targets which move within cluttered background. In recent years, biologists have found that a class of neurons in the lobula complex, called STMDs (small target motion detectors) which have extreme selectivity for small targets moving within visual clutter. At the same time, some researchers assert that lateral inhibition plays an important...
