You have reached the website of Annette Werner. My research interests focus on human and animal vision,
in particular on colour vision. Human colour perception is a construction of the brain, rather than a 1:1 translation of incoming sensory information.
This is impressively demonstrated by visual illusions like #thedress (different viewers report extremely different colour percepts when viewing the identical picture of a dress)
or the phenomenon of colour constancy (colours of objects remain approximately constant despite significant changes of the illumination).
My research aims to understand the neural processes underlying these colour phenomena,
i.e. colour perception and constancy in natural scenes, colour ambiguities, and the effects of gentherapy and of ageing.
In an interspecies approach towards understanding the general principles of colour coding, I also study colour and object recognition in the honeybee Apis mellifera,
the fascinating invertebrate model for perception, learning and cognition.
