You know what we feel as a human, we are a bit entitled – and we think that we’re always thinking about something – but actually we are not always thinking about something.
But, our brain has functions to do constantly, because it’s managing our basic functions that we are staying alive, our organs are working, our tissues are communicating. So, these are basic functions of the brain, which is not necessarily extra effort, extra activation, but it is there, and it’s constantly working.
But of course, if we are thinking, what are the most active times – these are the times that we are trying to learn something. We are trying to solve a problem which requires our brain to gather all the knowledge you know already, that it’s in the memory. Then it’s trying to make something new out of it because you’re facing a problem. So, in those moments the brain makes a little bit of higher activation than its usual state.
Interestingly, in one part of our sleep, that brain gets the most active prime time. This is why sleeping is so essential if you are in the process of learning something. We should definitely focus on our sleep, as well as sitting and studying, because our brain processes the information that we put in during the day at night, when we are sleeping.
So imagine the brain is someone that has so many different things, then at night, the other so many different things get a bit low. You don’t have to consider how the body is walking, or you don’t have to deal with digestion because the person has stopped eating.
So, what you need to do at that time is focus on what is the new information taken in the day. So then you make them in the memory, process them, and then complete the learning, for example. This is why it reaches a level that it’s quite active at a certain time of our sleep, but not the same reasons that it is being active during the day maybe.
So, this is why learning and problem solving, and the processing at night, is one of the times that the brain is most active.
