Brain circuit discovery illuminates circadian rhythms, psychiatric disorders with seasonal flare-ups For a considerable time, scientists have been captivated by the intricate workings of the brain, particularly when it comes to seasonal trends in mental illnesses and circadian rhythms. New insights into possible treatments have been provided by recent research that has illuminated the ways in which particular brain circuits regulate these rhythms and illnesses. Circadian Rhythms: The Body's Internal Clock Circadian rhythms are biological processes that follow a roughly 24-hour cycle, regulating sleep, wakefulness, hormone release, and other vital functions. These rhythms are primarily governed by the suprachiasmatic nucleus (SCN), a small region in the hypothalamus. The SCN receives light information from the eyes and adjusts the body's internal clock accordingly. Understanding the precise mechanisms of the SCN and its interactions with other brain regions is crucial for
