"Four men and two women, although the gender is not very balanced, but it doesn't matter." Kenichi Amamiya stood in the laboratory, looking at the bound Uchiha ninjas, and showed a smile of satisfaction.

The six ninjas of the Uchiha clan are enough to do their own experiments, but it is a question of who the first experimental subject picks, after all, although Kenichi Amamiya knows some knowledge about the brain, he doesn't know it very comprehensively.

So the first consumable is the most likely to die.

Kenichi Amamiya simply came up with a traditional game of turnips, and soon he picked a lucky one, a male ninja who looked a little handsome.

"The part of the human brain that controls emotions should be the amygdala area. But that position" Kenichi Amamiya looked at the Uchiha ninja who was tied to the operating table, with a pensive expression.

The human brain is very magical, even in the ninja world, there is not much research on the brain, after all, it is easy to accidentally kill people, maybe Tsunade will know some.

And the place where humans control emotions is in the amygdala area of the brain, and the reason why Kenichi Amamiya knows this is because one of his classmates studied medicine in college, brain.

So when Kenichi Amamiya used to chat with his classmates when he was idle, he once heard his classmates talk about it.

"If it's at the bottom of the brain, it's not easy to do research if you make a hole from above, and I remember that location is at the bottom of the brain." Kenichi Amamiya was thoughtful, and then he pulled out a book, which was given to him by the teacher.

There were some ninjutsu books about human experiments, and he remembered that one of them was a ninjutsu developed by a teacher, a very unique ninjutsu.

"Found it, this is it." Amamiya Kenichi nodded with satisfaction, I have to say that a teacher is a teacher, this talent is really nothing, this kind of ninjutsu can be developed, and I don't know how to do it.

Amamiya Ken took a look at this ninjutsu, the sealing step is not very cumbersome, the only thing that needs to be paid attention to is the preparation of a special nutrient solution, fortunately, those things Amamiya Kenichi also has here.

So next, Kenichi Amamiya took the scalpel and tried it, and sure enough, the sharp scalpel could only cut the scalp, but it had little effect on the hard skull.

"No wonder the old classmates in my previous life said that craniotomy is the same as doing stone processing." Kenichi Amamiya pursed his lips, he put down the scalpel, and then took out a small circular saw and began to cut the skull of the Uchiha ninja.

Soon, a large piece of the skull was taken out by Kenichi Amamiya, and the next step was the most critical step.

sealed, and then performed ninjutsu, taking the Uchiha ninja's brain out of his head, and then placing it in the nutrient solution on the side, and the chakra was densely connected to the opponent's brain and empty head.

After putting in the nutrient solution, the Uchiha ninja shuddered all over, and his brain fluttered a little.

Ken Amamiya recorded this, probably because the brain is not very adaptable to the new environment, and now the conduction of blood vessels and nerves is carried out through the connection formed by chakra, so there may be some problems.

But this is also the first time Kenichi Amamiya has seen this.

A unique scene.

The human brain can be taken out of the brain, and it will not affect the normal function of the brain, in order to verify this, Amamiya Kenichi directly solved the illusion of this Uchiha ninja, otherwise there would be no way to continue the experiment.

"Where am I?" Soon, the lucky Uchiha woke up, and he opened his eyes blankly and looked around.

[Subject's cognition and five senses do not appear to be affected in any way.] Kenichi Amamiya wrote it in the experiment log.

But soon, the sharp pain in his head made him sober up a little, and he subconsciously reached out to touch his head, but he touched a hard glass.

[The motor nerve is currently observed to be normal, and this ninjutsu to the brain does have the characteristics that the teacher said has almost no effect.] Kenichi Amamiya is very satisfied, so he can do the experiment perfectly.

"Are you awake? Don't move, or you'll be dead. "Kenichi Amamiya is busy checking the instruments, and the instruments used to monitor brain fluctuations are still quite expensive, and Kenichi Amamiya is reluctant to break them.

[The recording device of brain waves can also work normally, and the other party doesn't seem to be aware of the current situation] Kenichi Amamiya adjusted the instrument, these are very important.

However, in order to prevent the other party from being too emotional, which led to some troublesome things, he still reminded the other party, although the other party could not exercise vigorously, after all, his whole body was restrained.

Then Kenichi Amamiya showed him a look in the mirror, and then he found that the other party's brain waves began to produce violent turmoil, which made him feel a little happy, did he react so much?

At this moment, the unknown Uchiha ninja was looking in the mirror with a horrified expression, the head above his eyebrows in the mirror was all gone, empty, and above was a glassware containing a blue liquid.

There was also a white flower brain inside, with something dense on it, and then it stretched straight down, connecting with his empty head.

"Don't be nervous, this is a sterile lab." Kenichi Amamiya comforted the mood of this ninja of the Uchiha clan, and he noticed that when the other party was particularly emotional, his eyes automatically opened, and it was a hook jade writing wheel eye.

Didn't such a stimulus lead to the evolution of the tanatama? But also, if you can evolve in this way, it won't be known as a cursed eye.

Could it be that the evolution of the chakra has to be related to sorrow?

Amamiya Kenichi frowned slightly.

Grief may seem simple, but it is actually a very complex brain activity, first of all, humans need to perceive, recognize and recognize grief, which is the work of the amygdala area.

Then learn about the various emotions and these memories, which has something to do with the hippocampus, which can store people's long-term memories, as well as emotional-related memories, so that people can realize the invisible thing of sadness.

It's like a baby, after they are born, they cry because they are hungry or have other needs, but babies and toddlers can't feel such a thing as sadness, and the pain will make them cry out loud.

Even if their loved ones die in front of them, they will not have any sadness, because they cannot recognize this yet.

Only when you grow up, learn a lot of things, form memories, and then encounter sad things, will you perceive this emotion, which will cause people to feel very sad.

But sadness also has a physiological response, so sadness also has a certain relationship with the hypothalamus, when people perceive sadness, the brain begins to function, which will cause people to feel heartache, tears can not stop flowing and so on.

So although the amygdala area is a key area for recognizing and adjusting emotions, sadness is more about the cooperation of the whole brain, which leads to the intense sadness that people feel.

And the most interesting thing is that although sadness is an emotion, which directly arises from the brain and acts on the brain, it also has an impact on other organs of the body.

People say things like 'sad heartbreak', which sounds adjectives, but the scary thing is that it can be a declarative word, and intense grief can cause a tear in the heart muscle, which can lead to an immediate heart attack, and to some extent a heartbreak.

"Okay, don't cry, aren't you dead yet?" Amamiya Ken glanced at the tear-eyed Uchiha ninja who was crying, and gently wiped away his tears.

You can't die now, and you'll die when I'm done with the experiment.

Kenichi Amamiya mobilized some yang-attribute chakra to stimulate the amygdala area of this Uchiha ninja, but he soon found that he had missed one point, that is, when the yang-attribute chakra acted on the brain, it seemed to have a stimulant-like effect.

Not to mention that it still acts directly on the amygdala area, and soon this ninja began to laugh uncontrollably,

But even in the case of Sage Mode, the other party will still not be able to control his laughter, so there is a laugh in the laboratory all the time, and the other party laughs and tears at the same time.

This Uchiha ninja's heart is desperate, but he wants to despair, but the joy that comes from his heart really makes him unable to despair, but he can't help but be happy, can't help but be happy.

He's going crazy.

You are hereby called. Forget it, my question." Kenichi Amamiya took a deep breath, he wanted to curse, but he couldn't help it, it was caused by his decision-making mistakes.

"Yang attribute chakra doesn't seem to have a way to stimulate the other party's sad secretion, so is it difficult to use yin attribute chakra?" Kenichi Amamiya used ninjutsu to clean up, and this Uchiha ninja was lying on the operating table with a red face at the moment.

If you don't know, you think that Kenichi Amamiya is doing something terrible, but only Kenichi Amamiya knows that he is really doing experiments in earnest!

The chakra of the yin and yang attribute is not talked about much in the early Hokage anime, but in fact, for a ninja, the change in the nature of the chakra attribute is basically something that must be mastered.

The only problem is that there are not many Yin attribute chakras in Amamiya Kenichi's body, although there are some compared to ordinary ninjas, and these Yin attribute chakras Amamiya Kenichi suspects that they appeared with the birth of his own writing wheel.

But at least for now, it can still provide some convenience for Kenichi Amamiya.

This chapter contains a small amount of medical knowledge and some nonsense, after all, I don't know if the yang attribute chakra has this effect
