Our circadian rhythm is controled by light, via photoreceptive proteins called “opsins”, like neuropsin and melanospsin.  Humans possess photoreceptors, like neuropsin, in just about every surface and subcutaneous area of the body – adipocytes (fat), retina, testes, epidermis (skin), hair follicles (in mice, but I’m sure will will find them in us humans as well)…. … Continue reading Neuropsin, a photoreceptor protein, can control circadian rhythm independent from the brain
