Photoreceptors convert light signals into what kind of signals?

Photoreceptors are specialized cells found in the retina of the eye that are responsible for detecting light. When light photons strike the photoreceptor cells, they trigger a biochemical change in the pigments contained within these cells. This change initiates a series of events that ultimately leads to the generation of an electrical signal.

This conversion process occurs through a series of phototransduction pathways, where the light energy is transformed into an electrical impulse. This electrical signal is then transmitted via the optic nerve to the brain, where it can be processed and interpreted as visual information. Therefore, the correct answer highlights that the primary role of photoreceptors is to convert light signals into electrical signals for the visual system to interpret.
