The stimulus energy must occur within the receptor's receptive field. The stimulus energy must match the specificity of the receptor. A generator potential in the associated sensory neuron must reach threshold. The stimulus energy must be converted into the energy of a graded potential. called a transduction potential.
Visual phototransduction is the sensory transduction of the visual system. It is a process by which light is converted into electrical signals in the rod cells, cone cells and photosensitive ganglion cells of the retina of the eye. The visual cycle is the biological conversion of a photon into an electrical signal in the retina. This process occurs via G-protein coupled receptors called opsins which contain the chromophore 11-cis retinal. 11-cis retinal is covalently linked to the opsin receptor via Schiff base forming retinylidene protein.
