Neuroscientists at University of Buffalo have identified a sleep-promoting circuit inside the brainstem or the primitive part of the brain, whose activity appears to be both necessary and sufficient to produce deep sleep. This is only the second ‘sleep node’ in the mammalian brain that was identified to serve this function. To demonstrate the sleep node’s function, the researchers used
Scientists have figured out why a small percentage of people require less than six hours of sleep, whereas the vast majority of humans need at least 8 hours a night to thrive.
Our memories are plastic and as such are constantly updated and refreshed every time we recall a past event. In this process, misinformation can slip to the point that false memories can form. A new study found that sleep deprivation significantly increases the chance of a person to develop false memories.
The Moon and sleep For centuries, people have thought that the Moon affects sleep patterns. But does it really? Many people report increased sleepiness when there is a full moon, and there have even been some studies linking the Moon with sleep patterns. However, a new study conducted by researchers from the Max Planck Institute of Psychiatry in Munich did not
Some people have very vivid dreams, others can’t remember a thing when they wake up about what they’ve dreamed the night before. It’s said that by studying your dreams, you in fact learn more about your true inner self since dreams are your subconscious’ projections, genuine and unaltered. What happens when you’re fully aware you’re dreaming and control what’s happening around
We sleep for roughly a third of our lifetime. All complex organisms sleep, one way or the other, and clearly this is a highly important aspect of biological functioning, otherwise nature wouldn’t had allow it. Oddly enough, we still know very little about what happens during sleep and it’s key functions. For one, it’s been proven that sleep plays a
The fat-tailed dwarf lemur, native to the marvelous isolated ecosystem of Madagascar, is the closest human relative known to hibernate. After studying the sleeping behavior of both captive and wild lemur specimens, scientists at Duke University have discovered a great deal about how hibernation works in lemurs. The key discovery is that they can go for days without the deepest part
A topic of great interest in neurology and psychology is memory. While a lot of efforts have been made towards identifying what mechanisms and processes govern memory formation and retrieval, very few things are understood with respect to its storage. This is because our memories aren’t static, they always shift position and become either more anchored – through repetition for
The findings of a new research at UCLA, suggest that cramming all night before a big test, something that we’ve all went through at least once in a point of our lives with personal mixed results, is generally counter-productive as the sleep deprivation acts its toll on cognitive performance. Whether we’re talking about high school or university, especially the latter, we’ve all
While there’s a common assumption that once with old age, sleep quality tends to deteriorate, a recent study published in the journal Sleep suggests that the opposite is actually true. Thus, the older you are, the higher the chances of you having a good night’s sleep. The conclusion came after more than 150,000 adults were telephone surveyed. A study conducted on
Dr. Allison Harvey, professor of clinical psychology at the University of California Berkeley, said there are two main reasons why the use of electronics may affect our sleep.
A recent study published by Berkeley UC concluded that an hour nap boosts the brain’s learning capacity and restores power, just like an email box. When it’s full, it needs a cleaning session – which is just what the nap does. So of course, what every student had to learn the hard way, when you study and do an all
Ever wake up in the morning and just couldn’t get out of bed? Did you ever have something to do and just didn’t have what it takes to do it? Well, all you lazy people, rejoice! In may not be your fault after all. A simple test could show whether difficulty in defeating your laziness is genetic or… laziness. Scientists
It’s still unclear how sleep deprivation affects us, as there are still so many things scientists have failed to understand about sleep itself. But now, neuroscientists at the Duke-NUS Graduate Medical School in Singapore have shown for the first time what happens to the visual perceptions of healthy but sleep-deprived people who struggle to stay awake, such as
Sleep is the state of natural rest observed in the mammals and birds, and in many reptiles, amphibians, and fish. It is very important and is generally characterized by a reduction in voluntary body movement, temporary blindness, decreased reaction to external stimuli, loss of consciousness, a reduction in audio receptivity, an increased rate of anabolism (the synthesis of cell structures),
