Enhancing Memory Formation Through Deep-Brain Stimulation During Sleep

Scientists at UCLA Health and Tel Aviv University have provided the first physiological evidence from inside the human brain supporting the dominant scientific theory on how the brain consolidates memory during sleep. They found that targeted deep-brain stimulation during a critical time in the sleep cycle appeared to improve memory consolidation. The researchers had created a real-time closed-loop system that listened to the brain's electrical signals and delivered gentle electrical pulses instructing the rapidly firing neurons to play in sync.
