Chapter 3150 【3150】The Circuit Is Here

The overseas big cow's brain was stimulated, started to move, and threw out: You seem to know them very well, Dr. Cao.

Cao Yong suddenly realized that he was talking too much, so he shut his mouth.

Doctor Tong, who was sitting next to him, looked at him again: What secret do you have that you didn't tell?

There are no secrets, if a secret is dug out, wouldn't it mean that people will be dug out. ——Cao Yong remained silent.

The more silent he was, the more suspicious everyone became.

Not to mention Dr. Tong's cool eyes again, several overseas doctors who were talking and guiding on the phone line suddenly changed their state, picked up a pen and wrote something on paper.

Medicine is based on anatomy. Surgeons who want to operate on the human body draw anatomical diagrams in advance to analyze the anatomical relationship.

Since someone tipped the board for the limbic system, draw the limbic system.

The limbic system, specifically, is not a separate anatomical and functional structure. Once again, to implement what Xie said, the organizations in the brain are closely connected with each other. In the words of common sense, it is called a lot of brain circuits.

Therefore, when drawing the limbic system, it is very difficult to express how many three-dimensional organs are layered on top of each other. It needs to be abstracted into two dimensions. The easiest way is to draw it as a circuit.

There are three limbic system circuits discovered by brain experts, just like the ring road passing through the tissues in the brain and circling back and forth.

A circuit first discovered by medical scientists is called the medial circuit, which starts from the brain septum, passes through the cingulate gyrus, hippocampus, fornix, mammillary body, and thalamic pathway to the anterior nucleus of the thalamus, and the signal from the anterior nucleus of the thalamus is directly transmitted by the thalamic pathway Insert the buckle back.

The second circuit was discovered by physicians as a supplement to the first circuit. It's like a driver driving on a highway, thinking that the highway around the city only goes around the city, but after walking for a while, he finds out, hey, this road leads to the highway around the provincial capital.

For this reason, the second circuit is called the basolateral limbic circuit, which circulates back and forth through the orbital gyrus of the frontal lobe, the prefrontal area of ​​the insula, the amygdala, and the orbital gyrus of the frontal lobe. Among them, the amygdala projects the signal like a projector to the dorsomedial nucleus area of ​​the thalamus.

There is an area where the inner loop and the outer loop co-exist, and this area is mainly concentrated in places such as the septal hypothalamus.

The third loop is called the defense response loop. As the name suggests, medical scientists have found that if this loop is greatly stimulated, the body will trigger a response similar to defense, such as restlessness, rapid breathing and pulse.

The anatomical "circuit" of the defense response loop goes like this, from the hypothalamus through some parts of the septum to the amygdala, and finally back to the hypothalamus.

After the drawing is completed, it will be found that the relationship between the meningioma and craniopharyngioma diagnosed preoperatively by the patient has an obvious anatomical position relationship with these brain circuits.

Pick up the magnetic resonance film and CT film, and then check and check the circuit, um, it seems to have a clue.

To say that it is completely unexpected? Impossible, only useless brain.

Student Wei picked up his pen and wrote down the anatomical diagrams. It's a pity that he couldn't memorize all the structures of the brain. After drawing a little bit, he scratched his head and had to look at the classmates next to him.

Geng and Pan moved their heads together, rustling, not knowing what they were talking about.

Classmate Wei had an idea and wanted to copy the notes of the most academic classmate Xie.

Turn around and look at classmate Xie's notes again: Arrow ghosts.

When he was sweating profusely, he met those hazel "Song cat's eyes".

It's over, this Song Mao took the opportunity to despise him as a scumbag again.

He was so angry that he wanted to yell.
