The fact that her memory has been modified makes Trini's back a little hairy, but there is no reason, is it because she is too sensitive?

"I have a question," Wang Longlong raised his hand, interrupting Trini's thoughts, and shook his head, "You say." ”

"Humans have more than 100 trillion synapses at the age of two, and 2 million new connections are formed every second.

This figure is twice as large as that of adults, but the brain development maturity rate at that time was only about 70%, why did this number decline after the brain matured? ”

Erhai: "It's because you were exposed to too little external information when you were two years old, and you were still crawling at that time." It doesn't take so many synapses to deal with the that you crawl around, Teacher Trini has said that if you use it, you will become weaker if you use it. ”

Liu Lili: "Why are you still crawling at the age of two, can you walk!" ”

Erhai: "Is there an essential difference?" Staying in a big fart place all day, your brain still needs to be organized. ”

Zhang Xiao: "When I was two years old, I had the most synapses, so wouldn't it be the best time to give children crazy output?" Maximize intellectual development! ”

Trini nodded:

"Yes, two years old is a good time to do intellectual development. If the connections in your brain are not used, the number of new connections will no longer grow proliferated, and the 'pruning' strategy will be replaced. By adulthood, the number of synapses has dropped by half.

Not only that, but the brain will continue to persistently implement the minimum consumption strategy, and gradually solidify the information that humans use frequently, such as eating, drinking, walking, etc., to form a subconscious.

This state is called 'flow', where you automatically trigger action without thinking or being aware of it.

In this way, over time, the brain can eventually maintain a usage level of 4%.

4% here does not mean that the number of synapses remains unchanged at about 50 trillion, but the amount of information processed by each connection is reduced to about 4% of the full load, that is, there is still 96% of the information processing power, which is not used by humans. ”

Liu Lili got another point: "So it seems that the brain is like having free will, it can't be that there is something else in the brain that controls my brain, right?" Suddenly a little frightened, his face stretched long: "Soul! ”

"You're still a Chinese ghost story!" Trini patted him on the back of the head:

"Maintaining a 4% usage rate, the daily caloric consumption of the brain already accounts for 20% of the total energy consumption of the human body, so scientific research believes that this is more of a rationality for the self-balance of biological organisms.

It's like you feel pain when you're burned by fire, but your bodily function warns you not to die! ”

Wang Longlong held his chin:

"Adults consume about 2,000 calories a day through a life support meal, but in fact, each life support meal has 2,500 calories, and the human body also consumes energy to digest a life support meal.

Will there be a ceiling for absorption and transformation? That is, if there are 10,000 calories in a living meal, we may only end up absorbing 5,000 calories? ”

Zhang Xiao looked at him: "There must be, if you eat too much, you won't be able to digest it, and it will be pulled out, or it will become fat." Can you still become a superman because you eat too much? ”

Trini also nodded: "Yes, there is a bottleneck for the human body to absorb energy through eating, which is determined by the body structure.

We have simulated that when the brain usage rate reaches about 10%, it is no longer enough for humans to provide the energy consumption of the brain on a subsistence diet.

If you want to exceed 10%, you must either have a breakthrough in life-sustaining meals, or you can connect other energy externally. ”

Wang Longlong touched his stomach: "No wonder I always feel hungry lately......"

Cui Ni rewarded her with a pair of white eyeballs: "Hehe, just this learning content is far from increasing your brain usage rate by 1 point, you are just hungry." ”

Evan looked at Trine, "What's your brain usage?" Have you ever measured it? He had always been amazed by Trini's memory and high intelligence, and he was very curious.

Trini thought for a while: "It's probably between 6% and 7%, it depends on how well your brain moves, and it used to reach 8% at its peak." ”

“7%！” Liu Lili opened his mouth wide: "Then your memory and information processing ability must be how much of our ordinary people!" ”

"Well, my memory is about ten times greater, and my information processing power should be about three times greater." However, because of the long-term influence of "alcohol", it is actually weaker than this, but Trini does not want to admit that she has become sluggish......

Zhang Xiaochang sighed:

"How do I think that according to this pruning strategy of the brain to maintain the lowest power consumption, the reason why I am who I am is is not because I have something growing in my brain, but because some of the things that were originally there have been cut off? So, now I'm the brain......"

"Hahahaha," Liu Lili said with a smile, "Maybe I was originally an artistic genius, and my brain cut off my artistic ability." Zhang Xiaobai glanced at him: "If you want to say that, I was originally a mathematical genius and a master of painting." ”

After a long silence, Trini spoke:

"Yes, you are who you are, not because of what you left behind, but because of what you have left behind in the course of your life.

If you choose money and abandon your beliefs, you will not necessarily become rich, but you must be a person without faith.

If you choose a career and abandon family affection, you will not necessarily become a person with a successful career, but you must be a person with weak family affection.

What life throws away in the process of choosing is who you really are.

Even if you want to make up for it when you become famous, it won't change the fact that you chose to abandon it, and you will do it the next time you choose, because that's you, and you've already trimmed these things. ”
