...Pauline N. C. Chanel; Nigel C. Bennett; Maria K. Oosthuizen ABSTRACT Highveld mole-rats ( Cryptomys hottentotus pretoriae ) are social rodents that inhabit networks of subterranean tunnels. In their natural environment, they are rarely exposed to light, and consequently their visual systems have...

Goodman; Jessica Ausborn; Catherine R. von Reyn ABSTRACT Spatially invariant feature detection is a property of many visual systems that rely on visual information provided by two eyes. However, how information across both eyes is integrated for invariant feature detection...

Nevertheless, visual systems can perform this task in a rapid and accurate manner. Humans and other animals can efficiently recognize...

... 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...
