    The brains of overseas experts were stimulated, and they started to think: You seem to know them very well, Dr. Cao.

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

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

    There is no secret. If the secret is dug up, people will be poached.  ¡ª¡ªCao 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.  Surgeons who want to operate on the human body should draw anatomical diagrams and analyze anatomical relationships in advance.

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

    The limbic system, specifically, is not an independent anatomical and functional structure.  Again, to implement what classmate Xie said, the organizations in the brain are closely connected with each other.  In common sense, it¡¯s 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.  A circuit first discovered by medical scientists is called the medial circuit. It starts from the septal area of ??the brain and passes through the cingulate gyrus, hippocampus, fornix, corpus, and thalamic pathway to the anterior thalamic nucleus. The signal from the anterior thalamic nucleus then passes through the thalamic pathway.

    Directly insert the buckle strap.

    The second circuit was discovered by medical scientists as a supplement to the first circuit.  It's like a driver driving on a highway, thinking that the Ring Expressway only circles the city. After walking for a while, he realizes, hey, this road leads to the Ring Road of the Provincial City.  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.  The amygdala projects signals 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 relationship with these brain circuits.

    Picking up the MRI and CT scans, I checked the lines again. Well, I seem to have a clue.

    I can't think of it?  It's impossible, the only way is to use your brain.

    Classmate Wei picked up his pen and started writing anatomy diagrams.  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.

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

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

    Turning around, I looked back 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 shout
