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 ...
Sleep deprivation, also known as sleep insufficiency [2] or sleeplessness, is the condition of not having adequate duration and/or quality of sleep to support decent alertness, performance, and health. It can be either chronic or acute and may vary widely in severity.
One of the important questions in sleep research is clearly defining the sleep state. This problem arises because sleep was traditionally defined as a state of consciousness and not as a physiological state, [14] [15] thus there was no clear definition of what minimum set of events constitute sleep and distinguish it from other states of partial or no consciousness.
Typical example of a sleep deprived college student who is unable to concentrate on her studies, leading to impaired learning and decreased academic performance. Sleep deprivation – the condition of not having enough sleep – is a common health issue for students in higher education. This issue has several underlying and negative ...

Current studies suggest that sleep contributes to improved and durable learning effects, by further strengthening connections in the absence of continued practice. [45] [58] [59] Both slow-wave and REM (rapid eye movement) stages of sleep may contribute to this process, via not-yet-understood mechanisms.

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.
