Optics and Information Processes of Horsefly Polarization Vision that Underlie Visual Searching
Abstract
The collaborative efforts have greatly expanded our knowledge and understanding of polarization vision, specifically concerning the architecture of the compound eye of horseflies. The photoreceptor anatomy and spectral characteristics of the Ljubljana work horsefly Tabanus bromius are now unravelled into exquisite detail. The study of the higher order processing in the neural network will be the challenge of the coming years. And how this results in the polarization-dependent behavior will be the next level. Present hypotheses concerning the involvement of the central photoreceptors in specific eye areas can now be well tested. Two further themes of high interest are understanding when polarization provides an information benefit for task specific behaviours and whether or not polarization vision in different arthropods follows the same rules. This last topic will be intensely pursued in the new grant, provided to the same team joined by the Wernet-group in Berlin.
