A long-term lack of sufficient sleep is linked to dementia and Alzheimer’s, but this new research suggests this is not due to brain clearing during sleep. All mammals sleep, yet we are note ...
For the first time a new study describes the synchronized oscillations during sleep that power the brain’s glymphatic system to help remove ‘waste’ associated with neurodegenerative diseases ...
Two new studies indicate the importance of getting a good night's sleep — with one study saying a lack of sleep may be sabotaging the brain’s ability to keep intrusive thoughts at bay.
Prior sleep deprivation increases the percentage of time spent in slow-wave sleep (SWS). Therefore, an individual who was previously sleep deprived will have a greater chance of experiencing sleep inertia. [4] [7] Adenosine levels in the brain progressively increase with sleep deprivation, and return to normal during sleep. Upon awakening with ...
Misalignments of the body's circadian pacemaker with the environment (e.g., jet lag, shift work, or other circadian rhythm sleep disorders) [7] Another underlying sleep disorder, such as narcolepsy, sleep apnea, [8] idiopathic hypersomnia, or restless legs syndrome; Disorders such as clinical depression or atypical depression [medical citation ...
At any time during this sleep mode, the EEG of one brain hemisphere indicates sleep while that of the other is equivalent to wakefulness. In some cases, the corresponding eye is open. This might allow the animal to reduce predator risk and sleep while swimming in water, though the animal may also be capable of sleeping at rest. [35] [36]
The study found that several sleep characteristics, including sleep quality, early morning awakening, and difficulty falling asleep or staying asleep, were linked to accelerated brain aging ...
Further research has revealed that the protein kinase A (PKA) signaling pathway is crucial to long-term memory. If PKA or protein synthesis inhibition occurs at certain moments during sleep, memory consolidation can be disrupted [citation needed]. In addition, mice with genetic inhibition of PKA have been shown to have long-term memory deficits ...
