The neuroscience of sleep is the study of the neuroscientific and physiological basis of the nature of sleep and its functions. Traditionally, sleep has been studied as part of psychology and medicine. [1] The study of sleep from a neuroscience perspective grew to prominence with advances in technology and the proliferation of neuroscience ...
Treatment. Cognitive behavioral therapy, caffeine (to induce alertness), sleeping pills. 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 ...
Slow Wave Sleep (SWS) is a highly active state unlike a state of brain quiescence as previously thought. Brain imaging data has shown that during NREM sleep the regional brain activity is influenced by the waking experience just passed. A study was done involving an experimental and a control group to have them learn to navigate a 3D maze.
Reduced duration of sleep, as well as an increase in time spent awake, are factors that highly contribute to the risk of traffic collisions, the severity and fatality rates of which are on the same level as driving under the influence of alcohol, [52] [53] with 19 hours of wakefulness corresponding to a BAC of 0.05%, and 24 hours of wakefulness ...
Sleep cycle. The sleep cycle is an oscillation between the slow-wave and REM (paradoxical) phases of sleep. It is sometimes called the ultradian sleep cycle, sleep–dream cycle, or REM-NREM cycle, to distinguish it from the circadian alternation between sleep and wakefulness. In humans, this cycle takes 70 to 110 minutes (90 ± 20 minutes). [1]
For people with insomnia who spend a significant amount of their time in bed awake, feeling anxious and irritated, sleep restriction therapy can help boost their sleep efficiency, making the bed a ...
Stress factors that lead to a lack of sleep. Stress, often fueled by overthinking, caffeine, and cortisol, disrupts sleep. Rumination prevents relaxation, while caffeine and cortisol heighten alertness. Sleep deprivation intensifies stress, creating a harmful cycle. This impacts daily function and overall well-being.
Sleep spindlesare bursts of neural oscillatory activitythat are generated by interplay of the thalamic reticular nucleus(TRN) and other thalamicnuclei during stage 2 NREM sleepin a frequency range of ~11 to 16 Hz (usually 12–14 Hz) with a duration of 0.5 seconds or greater (usually 0.5–1.5 seconds). [1][2][3]After generation as an ...
