Studying the morphology, composition and function of the photoreceptor primary cilium in zebrafish.

Vision is one of our dominant senses and its loss has a profound impact on the life quality of affected individuals. Highly specialized neurons in the retina called photoreceptors convert photons into neuronal responses. This conversion of photons is mediated by light sensitive opsin proteins, which are found in the outer segments of the photoreceptors.

Color vision: Parsing spectral information for opponent color vision in the fish retina.

Environmental light carries spectral information, perceived as color. A new study in zebrafish shows how spectral information decoded by the cones' photoreceptors is transformed by retinal bipolar cells, adding a temporal component to the signal and establishing a third opponent axis for color vision.
