Besides wakeful rest, sleep is also important for learning. The Division of Sleep Medicine at Harvard Medical School (HMS) notes that sleep helps people to learn in two ways. A report on the school’s website explains that “a sleep-deprived person cannot focus attention well and therefore ...
“Interestingly, the team found that a sleep-deprived brain can normally process simple visuals, like flashing checkerboards. But the ‘higher visual areas’ – those that are responsible for making sense of what we see – didn’t function well,” said Dr. Michael Chee, lead author and profe...
When an animal is awake, the brain constantly buzzes with activity. During sleep, however, brain waves slow down and stretch out. When Lee started reviewing the data, he was surprised to discover the birds, slept in four-second intervals throughout the day and night while looking after their...
This measures electric activity of the wearer's brain, and communicates wirelessly with a clock unit near the bed. You program the clock with the latest time at which you want to be wakened, and it then at the proper time wakes you during the last light sleep phase before that. The ...
Sleep has profound importance in our lives, such that we spend a considerable proportion of our time engaging in it. Sleep enables the body, including the brain, to recover metabolically, but contemporary research has been moving to focus on the active r

While scientists continue exploring the restorative mechanisms behind sleep, we can be sure that slipping into slumber is a necessity if we want to maintain our health and our sanity. TED科普小视频: How playing an instrument bene...
on their own, even if the animal itself is acting as if it's fully awake. If that's what happens in humans, it means that regions of your sleep-deprived brain are simply checking out for stretches of time even while you're still up and about, which can lead to all kinds of havoc...
inflammation, malfunction, or destruction of brain cells or brain tissue. A lesion may be localized to one part of the brain, or it may be widespread. The initial damage may be so small as to not produce any initial symptoms but progresses over time to cause obvious physical and mental ...
A study led by UCLA researchers found that the brain slowed in sleep-deprived participants, leading to more mistakes during tasks. Because lack of sleep disrupts communication between brain cells, it also affects the ability of these cells to encode information and interpret visual signals.3 Boredom...
