the sleep stage where we spend the most time. (1) Brain wave activity during N2 sleep includes sleep spindles and K-complexes (or long delta waves). While sleep spindles and K-complexes both play a central role in memory consolidation, K-complexes also play a role in maintaining sleep. (...
sleep spindles The dual-process hypothesis of sleep describes a. how the slow-wave sleep early in the night brings activation levels down so the brain can be refreshed and less important memories can fade. b. how random activity in lower brain centers results in the m Short bursts of ...
There lies a paradox in sleep. Its apparent tranquility juxtaposes with the brain’s bustling activity. The night is still, but the brain is far from dormant. During sleep, brain cells produce bursts of electrical pulses that cumulate into rhythmic waves – a sign of heightened brain ...
is a potential avenue for treatment. Though the field is in its infancy, most attempts to do so have focused on an interesting quirk of the system. This is that glymphatic fluid moves through the brain only during sleep. The plumbing is disabled during waking hours, and is most active duri...
sleepbrain waveThe article focuses on brain's waste removal process during sleep, highlighting research in mice that suggests brain waves play a crucial role in flushing out waste through coordinated neuronal activity, with potential implications for neurological conditions like Alzheimer's & Pa...

During the memory task, researchers found that the “wake” slow waves reduced nerve cell activity and so affected cognitive performance – increasing the length of time required by patients to complete the task. The team reported that for each increase of one slow wave per second, the reaction...
When we go tosleep, our brain’s electrical activity slows down. The higher-frequency brainwaves that dominate while we are awake, called beta waves, are gradually replaced by lower-frequency ones called delta waves. The deepest, most restorative stage of sleep – called slow-wave sleep – h...

2. That brain activity, at least according to this newresearch, makes it harder to get the sleep people need to wake upwell rested in the morning.至少这项新的研究表明,这一大脑活动让人们更难以得到所需的睡眠,这样他们清晨醒来就不会精力充沛。句中it作形式宾语,真正的宾语为后面的动词不定式短语to...
