Do you and your friends ever talk about your dreams with each other? If you do, you might have noticed something interesting – some of your friends seldom remember their dreams, but some can always describe their dreams so clearly that it seems like they're describing things that really happened to them. What makes those people different?
The answer is simple. There are two different types of dreamers – low dream recallers(回忆者)and high dream recallers.
Low dream recallers usually remember their dreams only twice a month. But high dream recallers are able to remember them about five mornings a week. And a new study suggests that activity in a certain part of the brain could have something to do with it, reported The Huffington Post.
Perrine Ruby, a French researcher at the Lyon Neuroscience Research Center, studied 41 people (21 high dream recallers and 20 low dream recallers) and recorded their brain activity.
She found that a part of the brain called the temporo-parietal junction (颞顶联合区) was more active in high dream recallers than in low dream recallers – both when they were sleeping and awake.
This brain area collects and processes(编程)information from the outside world. This means that high dream recallers know more about what's happening around them. For example, when they are awake, they respond (对……有反应) more strongly to hearing their own names, and when they are sleeping, they are woken more easily by sounds and movements.
By closely studying people's brain activities, Ruby found that high dream recallers have twice as much “wakefulness time” during sleep as low dream recallers do. And it is during these short times of wakefulness that the brain remembers dreams.
“The sleeping brain is not able to remember new information,” Ruby told The Washington Post. “It needs to wake up to be able to do that.”
This is not hard to understand. Just try to think of your own sleeping experiences. If you are worried during the night, you are more likely to remember your dreams, but if you sleep well, you will remember little in the morning, and this is because “you never get a chance to remember”, Robert Stickgold, a Harvard Medical School researcher, told The Washington Post.
Honey to treat a wound. Eat cherries(樱桃) if someone has a pain in his knee. Your grandmother is probably satisfied with her old-time treatments and now science is catching up with them. Researchers have produced hundreds of studies in the past five years about these grandmothers' old-time home treatments. They are often natural, different from the medicine from the hospitals. Here are some old-time treatments which have been proved(证明) to be useful by the scientists.
Burns Try Aloe
"Aloe is a useful treatment for burns," says a doctor. Once study showed it was very useful for second-degree burns. If you have an aloe plant, simply cut open a leaf and use the liquid (汁液) directly to the burnt area. For serious burns, you should still see a doctor. | Eye Pains Try Cucumber
II you use your eyes for a long time, lie on your back and place one piece of cucumber over each closed eye. Cucumber helps reduce the pain. Replace the pieces with a cooler pair every two or three minutes, for up to 15 minutes total. | Wounds Try Honey
Since ancient Egyptian times, people have used honey to treat the wounds. For best results, scientists advised manuka honey, from New Zealand. Brush some honey directly to a wound every 12 to 24 hours and cover it with a piece of clean cloth. |
