Although photoreceptors are neurons, they do not conduct action potentials with the exception of the photosensitive ganglion cell – which are involved mainly in the regulation of circadian rhythms, melatonin, and pupil dilation.
Are cones and rods neurons?
The neurons of the central retina send different kinds of message than those sent in the peripheral retina. ... In its bare essentials, the retina transmits signals by a three-neuron pathway. Photoreceptor cells (rods and cones) detect light. They synapse upon a second type of neuron, the bipolar cell.
