They project to the pretectum, which via the Edinger-Westphal nucleus mediates the pupillary light reflex.
Their differences can be traced to AMPA vs. metabotropic glutamate receptors at the outer plexiform layer that invert the signs preserved in the inner plexiform layer. Peter Schiller found that two types of them can be selectively inactivated, resulting in deficits in bright and dark detection. They project to the pretectum, which via the Edinger-Westphal nucleus mediates the pupillary light reflex. They also project to the superior colliculus in coordinating eye movements and to the suprachiasmatic nucleus for directing circadian rhythms. Stephen Kuffler found that they respond to luminance contrast, and are found in P and M, and on-center and off-center varieties. For 10 points, name these cells whose axons make up the optic nerve leaving the retina.
