NDRC researchers have shed new lights on the correlation between sunlight exposure and related neurobehaviors. Combining single-cell mass spectrometry isotopic labeling technique, the multi-institutional team led by Prof. Wei Xiong and Prof. Guangming Huang uncovered a novel sunlight-activated glutamate biosynthetic pathway in the mouse brain. Such pathway may fundamentally contribute to our daily neurobehaviors such as mood, learning and cognition. The research article entitled Moderate UV Exposure Enhances Learning and Memory by Promoting a Novel Glutamate Biosynthetic Pathway in the Brain is published in Cell on May 17th.
