There may be ways to use the time you fall asleep, at least more than you already do. The researchers found that the brain can learn a new, small study that is based on the nature of new information, involving sleep and a large amount of white noise.
In one lab, the researchers connected 20 people to sensors, emitting white noise, spreading other noise segments and allowing them to identify sound patterns. Then, they fall asleep, because of the white noise and the other sound (some of the same, some new), always hanging the sensor. In the morning, they wake up and the last time they hear white noise and other sounds. The researchers found that in the morning, participants could pick patterns that they had heard when they woke up the night before, and that was expected. But more importantly, participants could also pick the patterns they heard during rem sleep, and they could remember that they played better than when they were awake. It’s clear that the brain has reached a certain point when it’s been ruled out.
On the other hand, the researchers found that sleepers do not remember the sound patterns they play during non-rem sleep, suggesting that your brain can also eliminate new information during sleep. As a reminder, rem sleep is the deepest sleep, while non-rem sleep is more relaxed and dreamless.
As Quartz says, this kind of learning is not entirely practical, and the participants subconsciously learn. But future research may bring this vague memory to the subconscious, so sleepers can learn useful things, such as names, hard data, and even new words.
