  Cao Yong suddenly realized that he was talking too much and closed his mouth.

   Dr. Tong, who was sitting next to him, looked at him again: what secrets did you not tell?

   There are no secrets, if the secrets are dug down, does it mean that people will be dug up. - Cao Yong remained silent.

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

   Not to mention Dr. Tong\'s glaring eyes again, several overseas doctors who spoke with their mouths along the phone line suddenly changed their status, picked up their pens and wrote something on the paper.

   Medicine is based on anatomy. When a surgeon wants to operate on a human body, he draws an anatomical diagram in advance to analyze the anatomical relationship.

  Since someone suggested that the board is a fringe system, draw the fringe 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 related to each other. In common sense, it is called a lot of brain circuits.

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

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

A circuit originally discovered by medical scientists is called the medial circuit. It starts from the septal area of ​​the brain and travels through the cingulate gyrus, hippocampus, fornix, corpus corpus, and thalamic pathways to the prethalamic nucleus. Insert the rebate strap directly.

   The second loop was discovered by physicians as a supplement to the first loop. For example, the driver drove on the highway, thinking that the highway around the city only circles the city, but after walking for a while, he found that, hey, this road leads to the highway around the provincial city.

   To this end, the second loop is called the basolateral limbic loop, which circulates back and forth through the orbital gyrus of the frontal lobe, the prefrontal region 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 have a common area, which is mainly concentrated in the hypothalamus of the septum.

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

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

After drawing   , it will be found that the meningioma and craniopharyngioma pre-diagnosed by the patient happen to be related to the brain circuit, and there is an obvious anatomical relationship with these brain circuits.

   Picked up the MRI ct film, and then checked the check line, um, it seems to have a clue.

  Is it completely unexpected? Impossible, only without moving your mind.

  Wei picked up his pen and wrote a piece of anatomy map. It\'s a pity that he couldn\'t 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.

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

  Student Wei had an idea and wanted to directly copy the notes of the most scholarly student Xie.

   Turned around and looked at Xie\'s note: Arrow ghosts.

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

After   , this cat Song took the opportunity to despise him again, this scumbag.

   so angry he wanted to yell.
