Cells respond to light

Article reads: Surprisingly, the researchers also found light-sensitive cells very early in the development of the brachiopod, before any neurons had formed, based on the expression of the light-sensitive gene ciliary opsin, which converts light into a chemical signal within the cell. This light-sensitive structure is unprecedented in terms of its morphological simplicity, being composed of only a single layer of cells on the surface of the embryo, and having no neuronal connections to other cells. These cells likely act individually, autonomously responding to light by changing the pattern of beating of cilia on their surface.
