Abstract
The biological functions of sleep have long eluded the medical and research community. In four consecutive issues of AIMS Neuroscience, original and review manuscripts were recently published regarding the mechanisms and function of sleep. These articles highlight the well-timed topic of quantitative sleep markers and cognitive functioning as one of extensive interest within the field of neuroscience. Our commentary on the original research performed by Cote, Milner, and Speth (2015) brings attention to the importance of examining individual differences in sleep and cognition in subjects with traumatic brain injury (TBI), and provides support for conducting similar sleep analyses in neurodevelopmental disorders.
