From a larger perspective, the intersection of the circadian photoreception and depression literatures that occurred throughout the 2000s began to provide a roadmap for how to escape the "hammer" approach that has long dominated phototherapy practice.
Although the visible light-sensitive opsins in ME photoreceptors have now been characterized, the functional relevance of visible light photoreception in MEs remains largely a mystery (see Introduction).
