Urban: His understanding is incredible, and he becomes an immortal starting from practicing martial

"If I enter the development period again, I will be able to improve the efficiency of my body and even my brain again in a short period of time. "

"If it was before, I would still need to do a detailed physical examination at the hospital. "

"But now I don't need it. "

As for the reason....

The reason is naturally that Bai Xuan's learning of sleep gong and inner dan gong has achieved certain results.

With the help of this achievement, we can perceive the subtle changes in the human body in more detail and make judgments.

"I had an inspiration last night, but there is still a part of the accumulation of knowledge, and after reading the human brain tonight, I will be able to roughly complete the optimization of the brain refining chapter. "

After getting dressed, Bai Xuan sat at the desk.

Since you want to exercise your brain, you naturally need to understand your brain.

Although modern science has not studied the brain thoroughly.

However, Bai Xuan was able to use his anti-heaven understanding to make up for the lack of knowledge in this part.

Anyway, though.

Naturally, the more knowledge, the better.

This thought flashed in Bai Xuan's mind, and Bai Xuan also opened "Human Brain".

The brain is the highest part of the nervous system, consisting of two cerebral hemispheres, the left and the right, and there are horizontal nerve fibers connected between the two hemispheres.

Each hemisphere includes: The cerebral cortex is a layer of gray matter on the surface, which is the concentrated part of the cell body of nerve cells.

The surface of the human brain has many concave sulcus with bulging gyrus between the sulcus, thus greatly increasing the area of the cerebral cortex.

The human cerebral cortex is the most developed, it is the organ of thinking, which dominates all the activities in the body and regulates the balance between the body and the surrounding environment, so the cerebral cortex is the material basis for high-level neural activities.

The brain's motor system is responsible for producing and controlling movement.

The resulting movement is transmitted from the brain through nerves to the body's motor neurons, where they control the muscles.

The corticospinal tract transmits motor information from the brain, spinal cord to the trunk and limbs, and the brain brain transmits motor information to the eyes, mouth, and facial area.

Large motor movements occur in the motor cortex and are divided into three parts: the primary motor cortex within the prefrontal gyrus, which is responsible for the movement of different body parts.

These movements are supported and regulated by two additional areas located in front of the main motor cortex: the anterior motor area and the auxiliary motor area.

In the motor cortex, the hands and mouth have a larger area than other body parts, which makes more precise movements possible.

The cerebellum and basal ganglia play a role in fine, complex, and coordinated muscle movements, and the connections between the cortex and basal ganglia control muscle tone, posture, and motor initiation, and are known as the extrapyramidal system.

The sensory nervous system is involved in the reception and processing of sensory information, which is transmitted to the brain through the reception of specific receptors.

The brain receives information about touch, pressure, pain, vibration and temperature from the skin and from the joints about the position of the joints, and the sensory cortex is located near the motor cortex and, like the motor cortex, has areas that correspond to the sensations of different body parts.

The sensory information collected by sensory receptors on the skin is converted into nerve signals that are transmitted to the brain through a bundle of neurons in the spinal cord.

Neurons extend up the posterior part of the spinal cord to the posterior part of the medulla, where they connect with "second-order" neurons.

These neurons then move up to connect with "tertiary" neurons in the thalamus, in parallel to the sensory cortex.

The spinal cord conducts information about pain, temperature, and total touch.

Neurons travel on the spinal cord and connect with second-order neurons in the reticular structure of the brainstem for pain and temperature, and can also make a general touch on the peritoneal complex of the medulla.

Vision is first stimulated by the retina connected to external light, which is picked up by cones and rods and converted into nerve signals, and eventually sent to the visual cortex in the occipital lobe.

Visual acuity in the left visual field falls on the right side of the retina and is conducted through the optic nerve to the lateral geniculate body, allowing all information about one side of the visual field to be projected onto the optic cortex of the brain on the opposite side.

Both hearing and balance are produced in the inner ear.

Balance is generated by the movement of fluid within the inner ear, while propagatory vibrations generated by the small bone bones are responsible for transmitting sound information.

They produce nerve signals through the vestibulo-cochlear nerve.

Nerve signals pass through the cochlear nucleus, the olive nucleus of the superior pole, the medial geniculate nucleus, and finally to the auditory cortex.

The sense of smell is produced by receptor cells in the olfactory mucosal epithelium in the nasal cavity.

This information travels through the relatively permeable part of the skull to the olfactory nerve, which carries the message to the olfactory cortex.

It is worth mentioning that of all sensory information, only olfactory information is transmitted directly to the cerebral cortex without passing through the nucleus on the thalamus.

Taste is produced by receptors on the tongue and along the facial and throat nerves to the brainstem, and some sensory information in the mouth is also transmitted from the pharynx to this area through the vagus nerve, from where it is transmitted through the thalamus to the cortex of taste.

Attempts to correlate basic emotions such as joy, anger, sorrow, and happiness in certain brain regions are highly controversial, and some studies have not found a specific location corresponding to emotions.

The amygdala, orbitofrontal cortex, insula, and lateral prefrontal cortex appear to be involved in emotional processing.

Executive function is an umbrella term for the set of cognitive processes necessary to allow cognitive control of behavior: he is responsible for selecting and successfully monitoring the behavior that promotes the achievement of the chosen goal.

Executive function filters out useless information and lowers stimuli unrelated to inhibition through attentional control and cognitive inhibition, processes and manipulates information held in working memory, the ability to think of multiple concepts at the same time, and switches tasks with cognitive flexibility, inhibits impulsive behavior, etc.

.........

A lot of knowledge poured into the brain, which naturally made Bai Xuan's understanding of the brain more in-depth and concrete.
