The purpose of this study is to understand how different intensities of light impact the brain in individuals with and without depression (seasonal and non-seasonal forms). Participation involves a screening assessment that lasts up to one hour and a single brain MRI scan procedure at the Brown MRF facility (within one to two weeks). Interested parties must have daytime availability during the work week.
