Webb16 apr. 2024 · Melanopsin is the photopigment that gives the pRGC cell its intrinsic photosensitivity [ 2, 3, 4, 5 ]. It is an opsin type of photopigment different from the rod opsin as well as different from the three types of cone opsins. All these different opsin types of pigments absorb different wavelengths. WebbThe photopigment of photoreceptive ganglion cells, melanopsin, is excited by light mainly in the blue portion of the visible spectrum (absorption peaks at ~480 nanometers [10] ). The phototransduction mechanism in these cells is not fully understood, but seems likely to resemble that in invertebrate rhabdomeric photoreceptors.
