Animals solve visual tasks of even outstanding complexity and difficulty with virtual ease. Trying to unravel the tricks and mechanisms that allow animals to satisfy everyday life requirements despite their often tiny brains motivates my research. The methods applied include thorough analysis of visually guided behaviour with high-speed cameras and targeted modifications of behaviour, electrophysiological investigation under conditions that come as close as possible to the natural ones, and model simulations.
