MNEMONIC Sound and Memory Study - Sleep, particularly deep sleep, is important for memory. Sleep deprivation can lead to difficulty with attention and memory performance. Enhancing deep sleep with medications has had limited success. We have recently developed a new approach to increase deep sleep by delivering sound waves played through headphones in a specific sequence during sleep in healthy people. When applied during sleep the sound waves increase deep sleep. The goal of this study is to determine the ability of auditory stimulation with these sound waves to improve memory performance.  Learn more by vising our Current Research Project page.

Phyllis C. Zee, MD, PhDHuman Timestamp: Traumatic Brain Injury - The purpose of this study is to develop a diagnostic test for individuals with disorders of circadian timing. We will evaluate the change in gene expression and metabolite profiles over the 24 hour period to determine whether changes to the internal clock can predict recovery from traumatic brain injury. Individuals who have been diagnosed with a mild traumatic brain injury within the past year are encouraged to participate.  Learn more by vising our Current Research Project page.

Jason C. Ong, PhDThe MATRICS Study - This study aims to investigate the effectiveness of different combinations and sequences of evidence-based treatment strategies for people with both Obstructive Sleep Apnea and Insomnia. Participants will be randomly assigned to one of three treatment conditions using a medical device known as CPAP, or using this device in combination with a behavioral treatment to improve sleep.
