The morning is wiser: how science confirms the proverb
The morning is wiser: how science confirms the proverb
"The morning is wiser than the evening" is an old saying. Quite a long time ago it was discovered that sleep has a direct relationship to memory and to the level of learning. But only very recently, scientists were able to substantiate this pattern by identifying the processes occurring during sleep.
Theory of synapses
There is a popular theory claiming thatduring sleep, the brain is cleansed of the excess information received for the day. According to her, during the day the brain cells, neurons, are constantly "bombarded" with various information from neighboring cells. During this process, there are connections between them, which are otherwise called synapses. By the time of sleep, the cells are not just filled, but overloaded with information, among which, among other things, there is absolutely useless. And at night, when information does not come from outside, the brain fundamentally rebuilds its activities, eliminating those synapses that do not have a useful load. A few years ago, American scientists have experimentally proved that during such night "cleansing" the space between neurons increases by about 60 percent. In these newly formed niches, the brain cells throw out the amyloid beta-beta accumulated during the day, which was developed during the day. This protein is classified as slag protein, which affects not only the memory process, but also the brain activity in general. Simultaneously with the removal of unnecessary synapses, the brain enlarges the useful ones to be able to perceive the necessary information the next day. That's why people whose work involves memorizing large amounts of information, for example, actors, are recommended to learn and fix fresh information in the morning.Sorting information
In addition to cleaning the brain from unnecessary information, at nightits sorting takes place. This theory came from physiology and is best known as the Hopsen-McCartley activation-synthetic theory. According to her, during the day, thinking about something or trying to solve some problem, the brain forms so-called memory circles associated with the most important events for a person. In the phase of fast sleep, also called sleep with dreams, chaotic disinhibition of certain areas of the brain and activation of memory circles occur. And most often in this process, the newly formed circles are involved, that is, those that are associated with a painful problem or task. Until the end it is not clear what is the incentive to launch these sites specifically. But their work during sleep allows using the previously described synapses to weed out the wrong variants and choose the most optimal ones. Therefore, often after waking up, a person makes the right decision, not even suspecting that he took it in a dream.
