Chapter 3150 [3150] The circuit is here

The brains of the overseas masters were stimulated and started to work, and they threw out: You seem to know them very well, Dr. Cao.

Cao Yong suddenly realized that he had spoken too much and closed his mouth.

Doctor Tong, who was sitting next to him, looked at him again: What secrets have you not told again?

If there is no secret, if the secret is dug out, then someone will be poached. - Cao Yong responded with silence.

The more silent he becomes, the more suspicious everyone becomes.

Not to mention Dr. Tong's glaring eyes, several overseas doctors who were talking and giving guidance on the phone line suddenly changed their state, picked up their pens and started writing on the paper.

Medicine is based on anatomy. When a surgeon wants to operate on the human body, he must first draw anatomical diagrams and analyze anatomical relationships.

Since someone suggested that the board is a marginal system, draw the marginal system.

Specifically speaking, the limbic system is not an independent anatomical and functional structure. Again, following what Xie said, the tissues in the brain are closely related to each other. In common sense, it is called brain circuits.

Therefore, when drawing the limbic system, it is very difficult to express how many three-dimensional organs are superimposed layer by layer. It needs to be abstracted into two dimensions. The simplest way is to draw it as a circuit.

There are currently three limbic system circuits discovered by brain experts, which are like a ring road that goes around and around the tissues in the brain. The first circuit discovered by medical scientists is called the medial circuit, which is located in the septal area of ​​the brain.

Starting from the cingulate gyrus, hippocampus, fornix, corpus, and thalamic pathway, it reaches the anterior thalamic nucleus. The signal from the anterior thalamic nucleus then passes through the thalamic pathway.

Insert the buckle strap directly.

When medical scientists discovered the second ring road, it was as a supplement to the first ring road. It’s like a driver driving on the highway and thinking that the ring road only circles the city. After walking for a while, he discovered that, hey, this road leads to the provincial capital.

Highway. For this reason, the second loop is called the basolateral limbic loop, 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 of the thalamus

The inner loop and the outer loop share a common area, which is mainly concentrated in 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, it will trigger the body to respond with a similar defensive nature, such as restlessness, accelerated breathing and pulse, etc.

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

After finishing the drawing, you will find that the relationship between the meningioma and craniopharyngioma that the patient initially diagnosed before surgery has an obvious anatomical position relationship with these brain circuits.

I picked up the MRI and CT scan and checked the circuit. Well, I seem to have a clue.

To say it's completely unexpected? It's impossible. You just have to use your brain.

Student Wei picked up his pen and started writing anatomical diagrams. Unfortunately, he failed to remember all the structures of the brain. After drawing a little, he scratched his head and had to look at the classmates next to him.

Classmates Geng and Pan put their heads together and rustled, wondering what they were talking about.

Classmate Wei had an idea and wanted to copy the notes of Classmate Xie, the most academically top student.

I turned around and looked at classmate Xie's notes: Arrow Ghost Drawing Talisman.

When he was sweating profusely, he came across those hazel brown "Song cat 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.
