City: I Will Practice Martial Arts A Little More And Become The Only Immortal!

"But Bai Xuan, your cerebellum is different.

"The narrow middle part of the cerebellum of ordinary people is called cerebellar worm. As the name suggests, it is similar to an earthworm, but Bai Xuan's is like a small snake."

"There are also cerebellar amygdala protrusions on both sides of the cerebellar vermis under the cerebellum, but Bai Xuan's is like a round bead."

"And this is only a change in appearance, Bai Xuan, you should understand that all differences in the brain represent very huge functional differences.

"so,"

"In terms of function, Bai Xuan, your cerebellum must have a huge gap with the cerebellum of ordinary people.

"It's just the specific differences, which still need to be tested and experimented."

Just saying that, Ye Zhuo's eyes became hotter and hotter.

He is really eager to know how different the brains of extraordinary people are from the brains of ordinary people.

And this difference represents countless academic papers and the most cutting-edge brain technology.

If you can study penetration.

He can easily change the world.

To know,

Human beings can be human beings.

The most important factor is that humans have intelligence.

The brain is the source of wisdom, which is why Ye chose to become a human brain scholar.

As long as the brain can be studied thoroughly, as long as human intelligence can reach a certain level, the world can be easily changed.

Even become a god!

after all

The hypothesis of God's forbidden zone is well-known all over the world!

According to research by scientists, human brain cells are usually only used by 5%, even those geniuses in the scientific and technological circles only use 7%, and more than 95% of the 660 brain cells are in a dormant state.

For a long time, people did not know why, so they pretended that it was sealed by the hand of God, lest human beings were too smart and broke many taboos in the heavens, so they used to call this part of the uncultivated brain area "God's forbidden zone".

If God's forbidden zone can be developed, the potential of the brain will be fully activated.

maybe,

Man can really be God.

Even if you can't become a god, it's good to be a superhuman.

Of course, Ye Zhuo has also studied extraordinary martial arts.

It is precisely because of the research that he understands the importance of the brain in breaking the limits of the human body.

And by studying Bai Xuan's brain, he understands the importance of the brain to a transcendent.

Without the evolution of the brain, superhumans will not be able to control bioelectricity and biomagnetic field, thus displaying superhuman powers!

"I know, I will fully cooperate with Professor Ye Deng in your experiment."

After receiving Bai Xuan's reply, Ye Zhuo couldn't wait to start testing and experimenting.

Through its rich afferent and efferent connections with the cerebrum, brainstem, and spinal cord, the cerebellum is involved in the regulation of body balance and muscle tone, as well as the coordination of voluntary movements.

Like a regulator.

Therefore, tests and experiments on cerebellum function mainly focus on three aspects: regulating body balance, regulating muscle tension, and coordinating voluntary movements.

"It's unbelievable, it's unbelievable."

While conducting the test, Ye Zhuo exclaimed.

he knows,

The regulation of body balance by the cerebellum is carried out by the flocculus lobe, that is, the cerebellum.

The balance adjustment of the body is a reflexive process, and the pompom nodules are the central device of this reflex activity (bhad).

The information of changes in body balance is sensed by the vestibular organ and transmitted to the flocculus lobe of the cerebellum through the vestibular nerve and vestibular nucleus, and the cerebellum sends out an impulse to adjust the body balance, and then reaches the motor neuron in the anterior horn of the spinal cord through the vestibulospinal tract. It reaches the muscles through the spinal nerve, coordinates the movement and tension of the related muscles, and keeps the body in balance.

For example, when a person stands and the head is tilted back, the knee and ankle joints will automatically flex to resist the shift of the body's center of gravity caused by the tilt of the head, so that the body can maintain balance without falling.

In this process, the auxiliary flexion movement of the knee and ankle joints to cooperate with the head tilting back is the result of the regulatory impulse issued by the cerebellum, which coordinates the movement and tension of the relevant muscles.

If the fluffy nodules are damaged, it will destroy the balance function of the body.

The monkeys whose pompom nodules were removed could not stand, and always sat in the corner of the cage, and kept their balance by supporting their bodies on both sides of the cage.

In humans, if the velvet lobe is damaged or compressed, the patient's body balance will be severely disturbed, the body will lean, and the gait will stumble when walking.

The research also shows that the vermis cortex also receives the input of proprioceptive and visual impulses related to body balance, and there are many fibers between the fastigial nucleus and the vestibular nucleus.

Thus, the longitudinal medial region, composed of the vermis cortex and the fastigial nucleus, is also involved in the regulation of body balance, mainly standing.

Damage to the medial region will also cause difficulty with balance and standing.

"Bai Xuan, your balance ability is really incredible."

"Your cerebellum seems to have derived a whole new set of balance programs, making you like a tumbler."

"No matter what the situation, you can restore equilibrium within five milliseconds."

"This balance ability is really inhuman."

"Not only that,"

"The same is true for your cerebellum in regulating muscle tension. It seems that a new system has been derived, and its ability to regulate muscle tension is far beyond ordinary people."

Ye Zhuo naturally knows that muscle tension is a basic reflex activity in which different muscle fiber groups in a muscle contract alternately, making the whole muscle in a state of frequent mild contraction, thus maintaining the standing posture of the body.

The cerebellum can regulate muscle tension activities, and its regulation is manifested in two aspects: inhibiting muscle tension and facilitating muscle tension.

The inhibitory effect of the cerebellum on muscle tension is mainly the function of the anterior lobe, and this inhibitory effect is most obvious in decerebrate animals.

Stimulating the vermis of the anterior lobe of the cerebellum in decerebrated cats can reduce the excessive tension of extensor muscles caused by decerebrated animals.

On the contrary, resection of this part strengthened decerebrate rigidity, these phenomena all indicate that the cerebellum has the function of inhibiting muscle tension. The facilitation of muscle tone by the cerebellum is carried out by the two sides of the anterior lobe.

Stimulating both sides of the anterior lobe of the monkey's cerebellum can strengthen the tense state of the extensor muscles and weaken the tension of the laminar muscles.

In humans, damage to this area causes muscle weakness or hypotonia. The inhibitory or facilitative effect of the anterior lobe of the cerebellum on muscle tension is realized through the muscle tension inhibition area and facilitation area in the brainstem reticular structure.

These two areas are the central parts of the control of skeletal muscle tension, and they control the activity of y motor neurons in the anterior horn of the spinal cord through the descending reticulospinal tract.

The descending impulse in the facilitation zone can strengthen the activity of y motor neurons and strengthen the muscle tension; the inhibition zone can weaken the activity of y motor neurons and weaken the muscle tension.

Under normal circumstances, the activities of the muscle tension inhibition area and facilitation area of ​​the brainstem reticular structure maintain a dynamic balance under the influence of the higher central brain, striatum, and cerebellum, thereby maintaining muscle tension at a normal level. state.

If, for some reason, the cerebellum's influence on the muscle tension inhibition zone or facilitation zone of the brainstem reticular structure is strengthened or weakened, the original balance between these two low-level centers will be destroyed, and the muscle tension activity will be strengthened or weakened. In addition, the cerebellum can also regulate muscle tone activity through the lateral vestibular nucleus.

From the lateral vestibular nucleus, the vestibulospinal tract reaches the spinal cord, and the tonic impulse passes through this descending conduction tract, which increases the activity of the motor neurons in the anterior horn of the spinal cord and strengthens muscle tension.

There are direct and indirect fiber projections via the fastigial nucleus from the vermis cortex of the cerebellum to the lateral vestibular nucleus.

The direct fiber projection is an inhibitory pathway to the lateral vestibular nucleus, which weakens the tonic activity of the lateral vestibular nucleus, and then reduces the activity level of the motor neurons in the anterior horn of the spinal cord, resulting in the weakening of muscle tension.

The indirect projection from the vermis cortex through the apical nucleus to the lateral vestibular nucleus is an excitatory pathway. The apical nucleus can strengthen the activity of the lateral vestibular nucleus through this pathway, and the final result is to strengthen the muscle tension activity.

Therefore, damage limited to the vermis cortex strengthened the transmission phenomenon in decerebrate animals; damage to the fastigial nucleus weakened the muscle tone in decerebrate animals.

And Bai Xuan's cerebellum is really too fast in regulating muscle tension.

Ordinary people may need more than two seconds, but Bai Xuan only needs two milliseconds.

This is a thousand times difference!

"I seem to have found the rules of brain evolution."

"The evolution of the brain is like the evolution of the computer, not only in the external structure, but also in the internal program.

"Interesting, it's really interesting."

Having said that, Ye Zhuo couldn't wait to carry out the third test, the test and experiment on the ability of the cerebellum to coordinate voluntary movements.

And this ability,

It is the most important ability of the cerebellum.

Because voluntary movement is the intentional movement launched by the cerebral cortex, and the coordination of voluntary movement is completed by the hemisphere part of the cerebellum, that is, the neocerebellum.

Damage to the neocerebellum will cause the victim's hypotonia and coordination disorder of voluntary movements, which is called cerebellar ataxia.

There are two main manifestations,

First, the accuracy of movement is hindered.

The phenomenon of intention tremor occurs. When the patient pays attention to doing a certain action, such as using the finger and nose, the finger trembles. The closer to the target, the stronger the finger tremor, so it is impossible to grasp the exact direction of the movement.

Second, the coordination of movements is impaired.

The patient loses the ability to stop one movement and immediately convert to the opposite direction, and the movement decomposition is discontinuous during movement.

For example, the patient cannot complete the simple and fast alternating movements such as flipping the palm quickly, which is called alternating movement disorder.

When completing a movement in one direction and need to change the direction of movement, the patient must first stop and think about the next step before starting a new movement.

All these listed symptoms are only manifested in sports, indicating that the neocerebellum plays an important coordination role in voluntary movement, and this coordination is the result of the cerebellum regulating the activities of the cerebral cortex and spinal cord. .
