Our unit seeks to discover the mechanisms underlying neuronal differentiation and neural circuit formation in the retina, using zebrafish as a vertebrate model. We also strive to determine the mechanisms underlying photoreceptor degeneration, to understand the pathological processes involved in human hereditary retinal diseases. Furthermore, in contrast to mammals, zebrafish have a remarkable ability to regenerate damaged neural circuits, which we study as an important avenue for medical research. Through these projects, we aim to discover the principles that govern the development of multicellular organisms and advance our understanding of the pathological processes of hereditary retinal diseases.
