Cellular and Molecular Anatomy
The basic blueprint of the retina is similar in all mammals (as in all vertebrates). However, in the course of evolution detailed but significant species-specific adaptations have occured in response to specific lifestyles and visual environments. Our comparative studies on mammals belonging to different orders are aimed at showing how flexible the retinal 'bauplan' is. The current focus is on the photoreceptor arrangements across mammals. We study the retinal distributions and proportions of cone and rod photoreceptors, e. g., in diurnal, nocturnal, subterranean and marine species. The assessment of spectral cone types allows predictions about colour vision.
