Studies using event-related potential (ERP) recordings have found that twenty-four hours of sleep deprivation decreases ERP response to signal inputs from endogenous, but not exogenous, sources. Therefore, it is suggested that sleep deprivation affects endogenously-driven selective attention to a greater extent than exogenously-driven selected ...

A microsleep is a sudden temporary episode of sleep or drowsiness which may last for a few seconds where an individual fails to respond to some arbitrary sensory input and becomes unconscious. [ 1 ] [ 2 ] Episodes of microsleep occur when an individual loses and regains awareness after a brief lapse in consciousness, often without warning, or ...
Young woman asleep over study materials. The relationship between sleep and memory has been studied since at least the early 19th century.Memory, the cognitive process of storing and retrieving past experiences, learning and recognition, [1] is a product of brain plasticity, the structural changes within synapses that create associations between stimuli.
Sleep deprivation is when you consistently don’t get enough sleep or are only getting poor-quality sleep. For instance, you might only get five hours of sleep most nights. Or maybe you’re in ...
Not getting enough sleep can seriously impair cognitive ability and executive functioning, leading to slower reaction times and poorer working memory or performance, Dr. Andrew Varga, a ...
During sleep, the hippocampus replays the events of the day for the neocortex. The neocortex then reviews and processes memories, which moves them into long-term memory. When one does not get enough sleep it makes it more difficult to learn as these neural connections are not as strong, resulting in a lower retention rate of memories.
Not getting enough sleep doesn't feel good -- and a new study suggests it could have some scary long-term consequences. Not getting enough sleep could increase your risk of Alzheimer's Skip to ...
