Study reveals new and essential details of how photoreceptors work

Moving around in the half-light is difficult but not impossible. To help us in this undertaking we have the rods, a type of light-sensitive cells (photoreceptors) present in the retina of vertebrates, capable of detecting very low lights which allow to move about even in poorly lit cellars or caves.
