New findings report the important role sleep plays and the brain mechanisms at work as sleep shapes memory, learning, and behavior.
One in five American adults show signs of chronic sleep deprivation, making the condition a widespread public health problem. Sleeplessness is related to health issues such as obesity, cardiovascular problems, and memory problems.
How sleep enables the remodeling of memories — including the weakening of irrelevant memories — and the coherent integration of old and new information.The common logic behind seemingly contradictory theories of how sleep remodels synapses, aiding cognition and memory consolidation.
“As these research findings show, we cannot underestimate the importance of a good night’s sleep,” said press conference moderator Clifford Saper, PhD, MD, from the Harvard Medical School, an expert on sleep and its deprivation. “Brain imaging and behavioral studies are illuminating the brain pathways that are blocked or contorted by sleep deprivation, and the risks this poses to learning, memory, and mental health.”
