What happens when a small brain structure associated with melatonin appears to relate to sleep differently in young people experiencing anxiety? In this nine-minute EXPRESS edition, Neil Hedley shares highlights from his conversation with Florida International University neuroscientist Dr. Aaron Mattfeld about the pineal gland, anxiety, adolescent sleep, and what the findings may mean. The research found an association, not proof that a larger gland causes sleeplessness; melatonin production was not measured directly. Want the full conversation?
