On the morning of January 18, Gu Jun, accompanied by Wu Shiyu and Cai Zixuan, walked into the building of the Institute of Psychology in the Medical Department of Tianji Bureau Headquarters.
After entering this unassuming building, they came to an advanced brain function research laboratory on the 5th floor, where Dr. Shen was waiting, as well as the head of the laboratory, Professor Ma Jun, and a group of researchers. Professor Ma is one of the best brain experts in China and is now a member of Gu Jun's treatment team.
Gu Jun's brain is in an abnormal state, he doesn't have any common mental disorders, there is no anxiety, depression, agitation, delirium, etc., and his temperament has not changed.
But as soon as he comes into contact with "abnormal" and "supernatural powers"-including Zug, dreamland, spells, illusions, alien worlds, R'lyeh, etc., he will have headache symptoms, and contact refers to including hearing Be heard by others, think by yourself, and participate in it from actions.
Hearing other people talking is the mildest symptom. If he just listens casually and doesn’t think about it, it’s just a headache; pain; if you participate in it yourself, it will be much more serious.
But regardless of the severity of the symptoms, when he discontinued contact, his headaches slowly subsided. If you don't touch it, nothing happens.
On the contrary, the longer the contact time, the heavier the pain will be, and the pain can lead to epilepsy, general rigidity and convulsions, and transient syncope.
Three days ago, Gu Jun in the ward was just a goa document sent by Master Tong. He hadn’t finished reading the document. After reading less than two pages, his whole body twitched and passed out, which really scared the people around him. Fortunately, just as the medical staff were about to start first aid, he woke up slowly.
Since then, the mood of the medical staff has sunk again, and everyone knows that there is a big trouble.
Gu Jun also knew that he was not optimistic, just like that, his mental exhaustion bottomed out, and he was tired and uncomfortable all over, and it took him a day to recover.
The human brain is too complicated. His brain has also grown tumors, suffered from hypoxia, been injured, and underwent surgery. Moreover, the injured and bleeding part is the right prefrontal lobe, and the lobotomy damages the prefrontal lobe area. It is very difficult to say what happened in this area.
There are traces that his condition is similar to post-traumatic stress disorder (ptsd), and "abnormal things" are his stressors.
Back then Jack Wells had ptsd symptoms, and some surviving personnel from other countries in the joint force also had mild ptsd symptoms.
But Gu Jun is different from them in that he has no typical clinical manifestations of ptsd, no invasive traumatic recurrence, no negative changes in cognition and mood, no hypervigilance, irritability and violent anger, etc., and he does not have such a self-assessment. In terms of psychological dilemma, I didn't want to avoid those event memories.
However, his brain shows a strong avoidance of things similar to or related to stress. Once faced with or exposed to related things, although there is no psychological pain, there will be a strong physiological reaction, which is in line with the diagnosis of ptsd .
Regarding Gu Jun's situation, the senior executives at the headquarters were very nervous, as were Tong Ye and Yao Shinian.
In terms of personal relationship, Master Tong and the others don't want to see Gu Jun like this; for the sake of the overall situation, they don't want Gu Jun to be able to get in touch with abnormalities anymore. In the past two years, Gu Jun's contribution and role need not be said. If he can't come back, it means that he can only rest for a long time and even retire...
So it is a huge loss for the Tianji Bureau and the people of the world.
It is precisely because of this that the treatment team once again has a heavy responsibility. Liu Mingfeng and other personnel who treat the body have left the stage, while Professor Ma Lin and other personnel who study the brain take on the heavy responsibility.
Their first task is to find out the pathological mechanism. Is it just Gu Jun's psychological problem, or his brain is damaged and disordered, which caused this situation.
Gu Jun had tried to use the Old Seal Purification Stone before, but no spiritual erosion was detected. He hasn't done the S-value test yet, and Dr. Shen and the others are worried that the impact of the traumatic scene may cause him to fall into a coma again, which will only make the situation more difficult.
At this time, Gu Jun, Wu Shiyu and Cai Zixuan walked into this laboratory. The advanced and complete equipment here can do some more detailed brain examinations for him.
The laboratory is very bright and spacious, divided into front rooms, and the front rooms are connected to several examination rooms with different equipment.
After everyone greeted, Gu Jun was taken to the fmri examination room by Professor Ma and others. fmri is functional magnetic resonance imaging. The equipment looks similar to nuclear magnetic resonance, but it does not need to inject radioactive substances during detection. The examination he will do is bold-fmri, which depends on functional magnetic resonance imaging of blood oxygen levels.
"This is a functional neuroimaging examination method." Dr. Shen explained to Wu Shiyu and the two, "A Jun will be asked to complete a stimulation task during the examination. By measuring the signal changes dependent on his blood oxygen level, it can reflect his local brain activity. This precise localization could help diagnose his pathology."
"I don't understand." Wu Shiyu looked at Gu Jun lying on the fmri equipment bed through the glass window of the examination room, "Dr. Shen, can you explain briefly?"
In fact, Cai Zixuan doesn't know much about fmri. Modern medicine has too many subdivided fields. If you don't specialize in neurology, you may not even have heard of them.
He came to check with his old friend because he was on vacation today, and he also wanted to study it. He only understood after reading some documents.
"That is to say." Dr. Shen thought for a while, and tried his best to speak in plain language: "If the neural activity in any brain area in the brain is enhanced, the blood flow will increase, and more oxygen molecules will be taken away than the actual number of active neurons. Oxygen consumption, so the increase in blood flow caused by neural activity will increase the blood oxygen content in the corresponding brain area, which is the bold signal. This can help us find out where the neural activity in the brain is enhanced when he is stressed."
Wu Shiyu nodded after hearing what Dr. Shen said, "Oh yes, I still don't understand."
"It's just..." Dr. Shen felt that it was necessary to explain it from the beginning, "The bold signal is the difference in the degree of influence of neuron activity on local oxygen consumption and cerebral blood flow, which changes the relative content of local deoxygenated hemoglobin, resulting in local The nature of the magnetic field changes…”
"Dr. Shen, the more I listen to you, the more confused I become." Wu Shiyu raised his hand to interrupt, "Let me first explain my understanding. Xian Jun did this test to photograph what was going on in his brain when he was stressed. Excited, find this position and judge what's wrong with him."
Cai Zixuan felt that she had understood correctly, and what she said was very clear.
"That's about it," said Dr. Shen, "but the brain is very complicated..."
While listening, Wu Shiyu thought, because her brain is super complicated, she can only understand it to this extent.
At the same time, the equipment in the examination room started to operate, and amidst the buzzing sound, the examination bed carrying Gu Jun moved towards the ring magnet.
