We spend more than 200,000 hours of our lives asleep, compared with perhaps 20,000 hours in formal education. Surprisingly, the effects of sleep on the brain remain poorly understood. This module will explore the impact of sleep on cognitive performance, drawing evidence from behavioural neuroscience, cognitive neuroscience and cognitive psychology methods. Although the module cuts across several strands of psychology, there will be a particular focus on the potential impact of sleep on memory and knowledge.
