Preferred Term:

rods (retina)

Definition:
Photosensitive afferent neurons located in the peripheral retina, with density increases radially away from the fovea centralis. Being much more sensitive to light than the retinal cone cells, the rod cells are responsible for twilight vision (at scotopic intensities) as well as peripheral vision, but provide no color discrimination.
