Researchers have discovered that stronger synaptic connections between neurons in the brain trigger deeper sleep.

Sleep deprivation typically results in longer and deeper sleep, thereby maintaining overall sleep quantity and quality ...

Contrary to the synaptic homeostasis theory, new work finds that reactivating memories during slow-wave sleep enhances learning and hippocampal activation. This may be useful for treating post ...

▲摘要：陆地光合作用每年清除的二氧化碳量是化石燃料排放的6倍。然而，通过分解后大部分的碳回到大气中。我们在地下2米处发现了一根3775年前的古原木，它的保存时间远远超过预期。这根木材保存得近乎完美，与现代样品相比，碳损失不到5%。它没有腐烂的原因可能是埋藏地点致密粘土的低渗透性。

9 月 16 日是中国脑健康日。一般大脑重量占体重的 2% 左右，虽然占比小，但责任大。作为人体的指挥中心，大脑要负责处理信息、控制感觉和运动功能、维持认知功能、管理情绪等。 如果大脑健康出了问题，会严重影响我们的生活质量。这篇文章盘点了大脑最怕的 10 件事，最后还会告诉大家保护大脑应该怎么吃，让健康从“头”开始。 民间传言：“酒是粮食精，越喝越年轻。”且慢，喝酒并不能让你越来越年轻，反而会加速 ...

144, No. 1, What is the Brain Good For? (Winter 2015), pp. 67-82 (16 pages) Sleep occupies roughly one-third of our lives, yet the scientific community is still not entirely clear on its purpose or ...

Have you ever wondered when kids stop napping? The answer is more complicated than you may think. Here, we break down why ...

Talking about Melatonin, Dr Meenakshi clarifies, “It promotes sleep by shifting circadian rhythm and increasing homeostatic drive to sleep. It is generally safe but should only be taken with proper ...

Sickness-induced sleep is a behavior conserved across species that promotes recovery from illness, yet the underlying mechanisms are poorly understood. Here, we show that interleukin-6-like cytokine ...

Editor’s note: This is part of a series called “The Day Tomorrow Began,” which explores the history of breakthroughs at UChicago. Learn more here. All human beings need sleep. We spend a third of our ...

To learn more about fitness age — and to check out the calculator — you’ll need to read the full article. Sleep drive, also called “homeostatic sleep drive” or “sleep pressure,” is one of two key ...
