Multi-Leveled Matched Filters Underlying Polarization Vision in Flies, Butterflies, and Moths
Abstract
The project aimed to investigate the adaptations of insect visual systems to detection of polarized light and color, to study the visual signals in animal and plant bodies, with flies and lepidopterans as the main model groups of organisms. The central hypothesis was that the light detecting tissues and neural circuits along the insect visual pathway filter the redundant visual information and allow for the optimal detection of visual contrasts, predominantly in the domain of polarized light, with minimal resources and computational efforts, while on the other hand, the visual signals aimed to convey the information to insect receivers or predators, reflect various designs and approaches to evoke maximally salient patterns of excitation in the nervous systems. The flies and butterflies were chosen as the main study groups because these are highly visual animals, capable of extremely fast and efficient processing of complex visual information (flies), or famous due to exceptionally complex utilization of color and polarization vision (butterflies), even in low light conditions (moths). Within flies, horseflies exhibit pronounced and robust utilization of polarization vision for object detection.
