Sleep is important for memory consolidation and cognitives performances during the day. There is increasing evidence that brain oscillations during sleep play a central role in such processes. This presentation will review recent work from our lab on the interplay between brain rhythms during sleep, memory consolidation and age-related cognitive decline. We will also discuss recent data showing the impact of sleep disturbances on cognitive functions, as well as the effects o...

This talk will discuss sleep of children as they transition to teens in the context of research that examines associations between brain systems that regulate sleep/wake behavior—the circadian timing system and the sleep homeostatic system. For example, adolescents’ circadian timing becomes later; their sleep “need” does not diminish; their sleep homeostatic system is also modified in a way that can modify sleep timing. A major implication of this work has been in the area of education, sp...

Sleep and circadian disturbances are common and represent risk factors for the development of some of the most prevalent and challenging chronic illnesses, such as cardio-metabolic and neurodegenerative disorders.Circadian rhythms are ubiquitous in all organisms. These rhythms, maintained through a complex molecular transcription-translation feedback loop are present throughout the brain and body, and play a key role in the regulation of nearly all physiological and behavioral processes.
