Rods are photoreceptors found in the retinas of vertebrates and are involved in non colour vision. Rods are highly specialised cells and permit vision in low light via the transduction light signals into chemical signals which can be sent to the brain. Rods produce a response by utilising G-proteins and the secondary messenger cGMP[1]
