This image captures a developing zebrafish embryo, a powerful model for exploring how the nervous system takes shape. The embryo is curled as it has not yet hatched. It expresses zebrabow, a genetic tool that fluorescently labels many cells, enabling researchers to visualize cell development and interactions in vivid detail. Because zebrafish embryos are transparent, they provide a window into the earliest stages of life, when the foundations of movement and sensation first emerge. The image has been falsely colored for artistic effect, highlighting the intricate beauty of developing structures that guide our understanding of both healthy and disordered development.
