Highlights
• Artificial light could indirectly damage dopamine neurons blunting the circadian rhythms of melatonin secretion.
• Artificial light could directly damage dopamine neuron by photoactivating biological relevant molecules.
• Light can modify the firing rate of dopamine neurons by activating opsins expressed in the substantia nigra.
• Excessive artificial light could be an adjunctive environmental risk factor for Parkinson’s disease.
