...Svetlana Volotsky; Ohad Ben-Shahar; Opher Donchin; Ronen Segev ABSTRACT Recognition of individual objects and their categorization is a complex computational task. Nevertheless, visual systems can perform this task in a rapid and accurate manner. Humans and other animals can efficiently recognize...

Taken together, the sexually dimorphic visual system of H. erato appears to have been shaped by both sexual selection and sex-specific natural selection. * Authors for correspondence ( abriscoe@uci.edu ; susan.finkbeiner@csulb.edu...

... is mediated by the activation of histamine-gated chloride channels (HCLs). These histaminergic synapses have been assumed to be conserved among insect visual systems. However, our understanding of the channels in question has thus far been based on studies in flies. In the butterfly Papilio xuthus , we have...

...Ilse M. Daly; Martin J. How; Julian C. Partridge; Nicholas W. Roberts ABSTRACT Stomatopods have an extraordinary visual system, incorporating independent movement of their eyes in all three degrees of rotational freedom. In this work, we demonstrate that in the peacock mantis shrimp, Odontodactylus...

Rodríguez-Gironés ABSTRACT Despite the strong relationship between insect vision and the spectral properties of flowers, the visual system has been studied in detail in only a few insect pollinator species. For instance, wavelength discrimination...
