Ji Dongping said 'sleep' instead of 'dormancy', and the meaning of this word is very different.

Organs in a dormant state may consume some of the subject's nutrients, but it will not affect the subject much. But the sleeping state of the organ ...... Once awakened, it is unknown what kind of impact it will have on the subject, especially since this organ is still a brain with the ability to think.

"Judging from the current data, the abnormality of the patient's mental state is likely to be related to the extra 'brain'." Ji Dongping said, pointing to the smaller part of the image.

Wang Yanfei stared at the picture on the screen for a long time, and said blankly: "Could it be ...... Parasitic fetus? Siamese people? ”

"It's possible, but there are no other problems in the patient's body, the problem is only the brain, I guess it should be in the early stage of embryonic development, when the nervous system was formed, there was a problem, and the part that should have developed the brain had an accident and grew an extra hemisphere."

Wang Yanfei frowned: "One more hemisphere?" ”

Ji Dongping pointed to the image: "You can see for yourself, there is no longitudinal fissure on the extra brain, we can see it as a hemisphere, and in terms of volume, this hemisphere just occupies one-third of the ventricles, which is equal to the volume of the other two hemispheres." ”

Wang Yanfei immediately understood that normal people's brains are divided into two hemispheres, the left and right hemispheres, but Luo Xiao's brain is divided into three, with an extra hemisphere. However, Luo Xiao's head looks normal and is not bigger than others, so each hemisphere of Luo Xiao's brain is smaller than that of a normal person.

But this didn't seem to affect Luo Xiao's intelligence, at least everyone who came into contact with Luo Xiao didn't think she had a problem with her intelligence. On the contrary, she is still a very intelligent person, which proves that although her cerebral hemispheres are smaller than others, her intelligence is not bad, and the potential of the human brain is huge, and modern medicine has long proved that even if there is only half of the brain, you can live like a normal person, and it will not even affect intelligence.

Wang Yanfei suddenly remembered something, and hurriedly found the brain wave map, judging from the data that was just twice as much as that of a normal person, she finally understood why Luo Xiao's brain wave map was so messy and irregular, it turned out that there were two waveforms interfering with each other.

"In this way, the original two hemispheres cooperate with each other like normal people, and the brain waves of the extra hemispheres are independent." Wang Yanfei thought carefully for a long time, and suddenly exclaimed: "Independent brain waves...... Independent thinking? ”

Ji Dongping nodded: "It is very likely that a similar situation has been recorded abroad, it is a pair of conjoined babies, they have independent brains, but they share a thalamus, brainstem and spinal cord. ”

Wang Yanfei also knew about this record, but this situation was too rare, and she never thought she could encounter it. looked at the image on the screen and said, "Could it be that Luo Xiao is also in this situation?" She...... Are they actually two people? ”

"Well...... It's hard to say, if you think spiritually, she should be counted as two people, but 'they' have only one pair of other body organs except for the brain, and they all share it. So...... Whether she's one person or two people, we can't say for sure. ”

Wang Yanfei suddenly realized a problem, if the previous diagnosis was wrong, Luo Xiao was not suffering from a brain tumor, then all the previous inferences about her condition would be overturned.

The tumor will continue to grow, but the brain will not, judging from Luo Xiao's current situation, her skull should be in a balanced state, and it may not be life-threatening. As a result, her remaining questions at the moment seem to be only mental?

Wang Yanfei was a little messy: "Could it be ...... Want to transfer Luo Xiao to psychiatry? ”

In many hospitals, the brain department and the psychiatric department are actually together, but there are also some hospitals that are separate, because mental abnormalities are sometimes caused by substantial brain lesions, and sometimes they are only caused by conscious and psychological factors. However, mental abnormalities can cause substantial brain lesions, so it is not easy to determine whether a person is 'mentally ill' or 'mentally ill'.

Luo Xiao's situation once again made Wang Yanfei feel like he didn't know where to start, and even wanted to escape.

Ji Dongping shook his head: "Even if you send her to the psychiatric department, the psychiatric department will send us back, and they can't solve this problem." ”

Wang Yanfei also knew that what Ji Dongping said was the truth, she just instinctively wanted to escape this problem. And she is a little inexplicably scared now, she has been in contact with Luo Xiao for more than half a year, and today I know Luo Xiao's 'true face', a brain tumor patient is nothing to be afraid of, but a person with two brains...... Wang Yanfei didn't know how to describe the fear in his heart.

"The patient has been mentally abnormal lately, and perhaps she should be hospitalized for observation for a while, so that we can determine how much this 'accessory brain' affects the 'main brain'. Maybe...... It is time for the patient to find out about her condition. Ji Dongping named Luo Xiao's two brains, the two hemispheres that occupy two-thirds of the space of the ventricles are called the main brain, and the extra hemisphere is called the accessory brain.

Wang Yanfei nodded, now that this situation cannot continue without the cooperation of the patient, it is time to let Luo Xiao understand his condition.

―――――――――――――――

After Zhang Hao and Luo Xiao had dinner, they went to a few places where Qi Youlin usually likes to go, but they found nothing. When she went home, Luo Xiao was probably tired and fell asleep in the car, Zhang Hao couldn't bear to wake her up, so he took her around his house several times until she woke up by herself.

"I ...... Am I asleep? Luo Xiao rubbed his eyes, stretched, and looked well rested.

Zhang Hao said: "Well, I've spared it several times. ”

"Why don't you wake me up."

"I didn't call you when I saw that you were tired, so I took it for a ride, and now let's go home, shall we?"

Luo Xiao nodded in response, his eyes were sly, and he suddenly leaned over and kissed Zhang Hao's face. Zhang Hao was a little inexplicable: "What are you doing?" ”

Luo Xiao smiled: "Kiss you." ”

Zhang Hao said with some embarrassment: "No, I mean, why is it so sudden?" ”

"It's nothing sudden, just kiss if you want to! That one...... Let's hurry home! A touching smile appeared on Luo Xiao's face.

Zhang Hao naturally understood the meaning of Luo Xiao's words, and he also smiled knowingly, and hurried home at a faster speed.
