Abstract:
Devices, systems and methods to modify memory and/or cognitive function by delivering a sensory stimulus paired with learned material at opportune physiological periods during sleep. Described herein are systems, methods and devices to enhance a user's cognitive function in memorization and learning. A machine (e.g., a system or device) may be used to identify opportune periods of the sleep cycle and to deliver a stimulus during specific phases of the sleep cycle to facilitate or interrupt memory consolidation. The machine may record ambient sensory inputs during awake acquisition or reinforcement/relearning and replay all or an extracted form of the ambient sensory stimuli during a specified portion of the user's sleep. A stimulus may be delivered to a user to affect brain activity during sleep to modulate the phase of a user's sleep, quality of sleep, and/or quality or intensity of brain rhythms during a particular phase of sleep.
