Samples were visualized on a light microscope under a 40x oil objective (Axioplan, Carl Zeiss Meditec, Dublin, Ca) and images captured by a digital camera (Cool SNAP; Roper Scientific, Duluth, Ga). In mice, ip RGCs mediate innate and corneal surface damage-induced light aversion (Johnson et al., 2010; Semo et al., 2010; Thompson et al., 2010; Matynia et al., 2012, 2015) and in patients, are important for migraine-associated photoallodynia (Noseda et al., 2010). Although pain can be felt in various ocular tissues, the retina itself does not sense pain. With nitroglycerin, these same mice with optic nerve crush exhibit significant light aversion. Retinal projections in mice with inherited retinal degeneration: implications for circadian photoentrainment. Furthermore, this retained light aversion remains dependent on melanopsin-expressing neurons. Ablation of melanopsin-expressing neurons reduces corneal mechanical sensitivity and light aversion, suggesting that melanopsin influences the function of both Aδ and C fibers, respectively (Matynia et al., 2015). The evolution of irradiance detection: melanopsin and the non-visual opsins.

Furthermore, trigeminal blink reflexes are retained after optic nerve transection (Dolgonos et al., 2011) and bright light induces markers of neuronal activity in the trigeminal nucleus caudalis in rats (Okamoto et al., 2009, 2010).

Here, we show that melanopsin is expressed in both human and mouse TG neurons.

In mice, they represent 3% of small TG neurons that are preferentially localized in the ophthalmic branch of the trigeminal nerve and are likely nociceptive C fibers and high-threshold mechanoreceptor Aδ fibers based on a strong size-function association.

Rods and cones are classic photoreceptors that underlie night vision and high acuity, color vision respectively.
