Chapter 455 The Effect of Physical Hormones on Thinking

The physical influence is actually the hormones produced by each human body that influence a person's decisions and even thinking and personality.

You know, many animals have "calf protection" behavior. Take mice as an example. Once the pups walk out of the nest, the mother will take them back to the safety of the home.

To understand the mechanism behind this behavior, the scientists carefully analyzed millions of cells in a part of the mouse brain called the medial preoptic area, which had been previously implicated in the behavior.

These studies have found a very interesting phenomenon: when the mother mouse finds her babies running out of the nest and decides to take them home, a few cells expressing estrogen receptors in this brain area are most active. When the babies return home, the activity of these cells begins to decline.

So could these cells be a key to maternal behavior? Scientists have found this out through a series of clever experiments.

First, the scientists chemically activated these cells in mother mice, and the study showed that once activated, the cells immediately sent mother mice searching for their babies.

Secondly, the researchers repeated the experiment on unmated mice and found that as long as these cells were artificially activated, the mice that had not yet become mothers would show great maternal love and bring the babies that were not their own back to the nest; finally, when the activity of these cells was inhibited, the corresponding maternal behavior disappeared.

In other words, this particular maternal behavior has long been written into the brains of animals!
Further research has clarified the role of dopamine in this process. It turns out that these nerve cells expressing estrogen receptors are mapped to the brain area that produces dopamine, and inhibiting cells in this brain area will also inhibit the generation of maternal love behavior. This shows that dopamine may be the key to driving this behavior.

Of course, it's not just animals, humans are the same. Female humans will also have emotions after giving birth, but humans have a higher level of thinking awareness and cognition, so they will be restrained and will not be as anxious as mice when they can't see their babies for a while. However, dopamine has already affected human thinking and decision-making.

In fact, it is not just dopamine. Studies have shown that other hormones produced in the human body can also affect human personality and thinking. Among them, four hormones closely related to personality and thinking have been discovered, namely dopamine, serotonin, testosterone and estrogen.

The hormone levels in the human body determine people's personality traits.

For example, people with high dopamine levels have active minds, are energetic, creative, adventurous, and pursue novelty.

People with high serotonin attributes are more easygoing and sociable, have conservative values, and are less willing to explore. People with high testosterone levels are usually strong-willed, straightforward, decisive, confident, and skeptical. This type of people are good at fields with clear rules, such as engineering, computers, and mathematics.

People with high estrogen attributes are more trusting of intuition, are imaginative and compassionate, and like to trust others.

These people are sensitive to other people's feelings and usually have good speaking and social skills.

These descriptions are relatively abstract. Let’s use vivid examples to explain these four personalities.

For example, millions of years ago on the African continent, a group of primitive people encountered a kind of mushroom they had never seen before. Dopamine-type people would want to try it, while serotonin-type people would stop them and say it was too dangerous.

The testosterone type would suggest that you feed mushrooms to your dog first and see what happens. The estrogen type would like you to sit down and talk about what you know about mushrooms.

It is precisely because of the different hormones in the body that people have different personalities. It is also precisely because people have different personalities that naturally people with different personalities complement each other.

However, as human consciousness becomes digital, human thinking is no longer affected by hormones secreted by the body. Therefore, at the beginning, people who have just become data conscious will express emotions such as love for their children due to the inertia of thinking.

However, as time goes by, people who become digitally conscious will naturally lose the need for family affection after they are no longer affected by the dopamine secreted by the body.

Instead, there is only one demand, that is, the need for survival. Even after being fully loaded with the need for survival, after a long time, the data consciousness cannot even show any fluctuations in consciousness. The consciousness that originally had fluctuations will directly turn into a bunch of garbled codes.

This is like the collapse of the power operating system, and this situation is especially obvious in elderly people who are experiencing consciousness transformation.

This type of people are very old, so they have experienced everything that has happened before and have no interest in anything. So naturally, their consciousness becomes calm and no longer fluctuates.

In fact, this situation reminded Liu Xiu of the Meng Po soup he had to drink before reincarnation. The purpose was naturally to forget what he had experienced in his previous life, so that even if he was reincarnated again, he would still feel fresh about everything and would not feel bored.

In fact, to be honest, Liu Xiu has lived for more than 200 years in his two lives combined. Therefore, if it were not for his sense of responsibility for the tens of billions of people living on the wandering blue planet and his curiosity about exploring the universe, Liu Xiu might also want to reincarnate!
Of course, after Liu Xiu ordered the killing of the bionic robot David, he had the diplomatic spacecraft that was prepared to be used to fight the alien blue planet stay in the space orbit of the alien blue planet to observe the final outcome of this planet occupied by the alien sex.

But so far it is still okay, because this alien is different from the Zerg, and so far there has been no alien queen or other creatures.

Compared with the Zerg, although the aliens look very powerful, they do not have the Zerg queen and superior intelligence. Therefore, after infecting and killing all the animals on the planet, these aliens began to wander aimlessly.

The reason for surveillance is naturally because they are afraid of the emergence of someone like the Zerg Queen who can control humans or build her own spaceships to leave this alien blue planet.

After all, if creatures like the Spore Alien find other life planets, the consequences will naturally be extremely terrible.

With the Alien Blue Star gone, the only intelligent civilization left in the universe is the Wandering Blue Star!

There was originally Pandora, but unfortunately, because no attention was paid to the aftereffects of the star destroyer fragments, Pandora was implicated instead.

After mining the superconducting ore on Pandora, the Wandering Blue Star returned to the star system where Origa VI is located.

Continue to help Planet Origa VI complete its planetary ecology.

Fortunately, although there are no living things on this planet, the atmospheric content is just right, so it is still very suitable for growing plants on the Wandering Blue Planet.

However, what Liu Xiu did not expect was that only more than ten years later, the unmanned probe that was originally launched towards the center of the Milky Way by the electromagnetic cannon actually made a major discovery.

Because many planets showing signs of life activities have been discovered in an area more than a thousand light years away from their area.
