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.
In a mouse study, researchers found that zolpidem (Ambien), a common sleep aid, could prevent the brain from effectively clearing up 'waste', though it remains unclear whether this could affect ...
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 ...
Chronic sleep deprivation also raises the brain's amyloid-beta aggregation, which is linked to neurodegenerative diseases like Alzheimer's. Impaired clearance mechanisms during reduced sleep worsen this neurotoxic environment.Neuroimaging studies also show a shift of cognitive resources, which decreases activation in the prefrontal cortex and ...
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]
Improvement to cognitive performance caused by exercise could last for 24 hours, a new study shows. Scientists also linked getting 6 or more hours of sleep to better memory test scores the next day.
One manifestation of the overconfidence effect is the tendency to overestimate one's standing on a dimension of judgment or performance. This subsection of overconfidence focuses on the certainty one feels in their own ability, performance, level of control, or chance of success.
“The results underscore the importance of having healthy blood pressure levels and prioritizing adequate sleep to maintain a healthy brain into old age. Doctors should be reminded to check ...
