Morning is wiser than evening: how science confirms the proverb

Synapse theory

There is a popular theory stating that during sleep, the brain is cleared of the excess information received during the day. According to her, during the day, brain cells, neurons, are constantly “bombarded” with various information from neighboring cells. In the course of this process, connections arise 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, is completely useless. And at night, when there is no information coming from outside, the brain is fundamentally restructuring its activities, eliminating those synapses that do not have a payload.
A few years ago, American scientists had experimentally proved that during such a nightly cleansing, the space between neurons increases by about 60 percent. Brain cells accumulated during the day, beta-amyloid, which was produced during the day, are released into the newly formed niches.This protein belongs to the slag proteins, which have a negative impact not only on the process of memorization, but also on the whole on the brain activity.
Simultaneously with the removal of unnecessary synapses, the brain enlarges the useful ones in order to be able to perceive the necessary information the next day. That is why people whose work is connected with memorizing large volumes of information, for example, actors, are recommended to memorize and fix fresh information in the morning.

Sort information

In addition to cleaning the brain from unnecessary information, it is sorted at night. 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 the so-called circles of memory associated with the most important events for a person. In the phase of REM sleep, also called dreaming, the chaotic disinhibition of certain areas of the brain and the activation of memory circles occur. And most often in this process newly formed circles are involved, that is, those that are associated with a sore problem or task.It has not been fully clarified what is the incentive to launch specifically these sections. But their work during sleep allows using the previously described synapses to weed out the wrong options and choose the most optimal ones.
Therefore, often after waking up, a person makes the right decision, not even suspecting that he accepted it in a dream.
