<P> Photoreceptor cells are capable of phototransduction, a process which converts light (electromagnetic radiation) into electrical signals . These signals are refined and controlled by the interactions with other types of neurons in the retina . </P> <P> The five basic classes of neurons within the retina are photoreceptor cells, bipolar cells, ganglion cells, horizontal cells, and amacrine cells . </P> <P> The basic circuitry of the retina incorporates a three - neuron chain consisting of the photoreceptor (either a rod or cone), bipolar cell, and the ganglion cell . </P> <P> The first action potential occurs in the retinal ganglion cell . This pathway is the most direct way for transmitting visual information to the brain . </P>
