“Sustained exposure to dim light led to a marked reduction in a peptide that maintains healthy connections and neurons in the hippocampus,” explains study author Antonio A. Nunez, Ph.D., professor of psychology and neuroscience at Michigan State University. “It also caused a reduction in dendritic spines, which are the connections that allow neurons to communicate with one another.” And although the study was performed on rats, Nunez believes that the results would also translate to humans because both species are active during the day and dormant at night.
