Enhance Memory and Skill Learning While Sleeping

Researchers at Teledyne Scientific & Imaging, LLC have developed a new approach that enhances memory and skill learning while people sleep. In experiments conducted on over 100 human subjects, they demonstrated an up to 25% improvement in memory compared to subjects that did not use the new device.

The approach leverages a phenomenon in the brain called memory replay which is thought to be involved in the transfer of information from short-term to long-term memory (a process termed consolidation) that takes place during sleep. The research focused on detecting biomarkers that indicated the brain was in the critical period of memory consolidation. Then,  by applying either a short sound or noninvasive electrical stimulation, they could trigger a boost in learning. The research suggests that this closed-loop approach, which tightly couples and prescribes interventions based on ongoing brain activity in real-time, significantly improves learning in real-world tasks in people.

The research was conducted as part of a large scale collaboration with researchers from RioGrande Neurosciences, the University of California at Riverside, and Intific Inc., and funded by the Defense Advanced Research Projects Agency's (DARPA) Restoring Active Memory (RAM) Replay program.

As part of their ongoing research, Teledyne has demonstrated that this approach improves learning across a number of domains. First, it improved learning to navigate a new 3D environment simulated in virtual reality. Here, participants who received the closed-loop intervention realized an almost 40% benefit in their navigation time compared to controls, indicating an increase in understanding and retention of the virtual city layout. Second, they have also demonstrated significant effects in boosting memory on more standard educational material. For example, they found that noninvasive electrical stimulation could improve an individual's test scores on lecture material by >10% (a full letter grade improvement) two days after the material was learned without any additional study of the material.  Finally, ongoing work is demonstrating an over 15% improvement on memory tests of facts.

 “Through this research we have gained great confidence that these approaches can make a difference in people's lives by enhancing learning on a number of different tasks.", says Dr. Stephen Simons who is the lead investigator for Teledyne's team on the project. “Furthermore, the noninvasive nature of these interventions and their application during sleep means that these benefits can be realized with minimal disruption to people's everyday routines."

Through part of the research, Teledyne has developed a prototype headband system that can easily and comfortably be worn while an individual sleeps. They are actively seeking partners to test and transition the technology to commercial applications.
