Chapter 348

On the morning of January 18, Gu Jun, accompanied by Wu Shiyu and Cai Zixuan, entered the Psychological Research Institute building.

After entering the modest building, they came to a brain advanced function research laboratory on the fifth floor. Dr. Shen was waiting there, 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, not ordinary mental disorders, anxiety, depression, agitation, delirium and so on, his temperament has not changed.

But when he comes into contact with "abnormal" and "supernatural forces" - including zuggos, illusions, incantations, visions, heretics, lalaier and so on, he will have headache symptoms. Contact refers to hearing other people's words, thinking and participating in actions.

Hearing others talk is the lightest symptom. If he just listens casually and doesn't think about it, his head will swell and ache; but once he hears into his brain and thinks about it by himself, the symptoms will rapidly aggravate and his brain will have strong cracking pain; if he participates in it in person, it will be more serious.

But regardless of the severity of the symptoms, when he interrupts contact, his headache will gradually subside. If you don't touch it, nothing happens.

On the contrary, the longer the exposure time, the heavier the pain, which can lead to the onset of generalized tonic and convulsive symptoms of epilepsy, as well as transient syncope.

Three days ago, Gu Jun was just reading a Goa document sent by Tong Yeh in the ward. He had not finished reading the document. After reading less than two pages, he was convulsed and fainted, which really scared the people around him. Fortunately, as soon as the medical staff began to give first aid, he slowly woke up.

After that, the mood of the medical staff went down again. We all know that there is a big problem.

Gu Jun also knew that he was not optimistic. For a moment, his mental exhaustion was at the bottom, and his whole body was tired and miserable. He was relieved for a day.

The human brain is too complex, his brain has also grown tumor, oxygen deficiency, injury, surgery. What's more, the site of bleeding is the right prefrontal lobe, which is damaged by lobectomy, which is very difficult to say.

There is evidence that his condition is similar to post-traumatic stress disorder (PTSD), and "abnormal things" are his stressors.

Jack wells had PTSD symptoms at that time. This time, survivors from other countries in the joint forces also had mild PTSD symptoms.

However, 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 excessive alertness, irritability and irritability, and so on. He has no psychological dilemma in this regard in his self-assessment, and he does not want to avoid the memory of those events.

However, his brain showed a strong avoidance of things similar to or related to stress. Once faced or contacted with the relevant things, although there was no psychological pain, there was a strong physiological reaction, which was consistent with the diagnosis of PTSD.

For Gu Jun's situation, the senior leaders of the headquarters are very nervous, as are Tong ye and Yao Shinian.

In terms of personal relationship, they don't want to see Gu Jun like this; for the sake of the overall situation, they don't want Gu Jun to stop contacting the abnormal. In the past two years, Gu Jun's contribution and role do not need to be said. If he can not be cured, it means that he can only take a long rest and even retire

So it is a huge loss to the National Bureau of natural science and the global public.

It is for this reason that the treatment team once again has a great responsibility. Liu Mingfeng and other people who treat the body leave, while Professor Ma Lin and other researchers who study the brain shoulder the heavy responsibility.

Their first task is to find out the pathological mechanism. Is this just Gu Jun's psychological problem or is his brain damaged and maladjusted that leads to this situation.

Gu Jun had tried to use the old Yinjing fossil before, but did not detect the spiritual erosion. He hasn't done an S-test yet, and they worry that the impact of the trauma 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 the laboratory, where advanced and complete equipment could do some more detailed brain examination for him.

The laboratory is very bright and spacious, divided into a front room, and the front room is connected with several inspection rooms with different equipment.

After everyone said hello, Gu Jun was taken to the fMRI examination room by Professor Ma and others. FMRI is functional magnetic resonance imaging (fMRI). The device looks like MRI, but it doesn't need to be injected with radioactive substances. His examination is BOLD-fMRI, blood oxygen level dependent fMRI.

"This is a functional neuroimaging test." Dr. Shen explained to Wu Shiyu, "during the examination, a Jun will be asked to complete the stimulation task. By measuring the signal changes of his blood oxygen level dependence, the activity of his local brain can be reflected. This accurate localization can help to diagnose his pathological mechanism."

"I don't understand." Through the glass window of the examination room, Wu Shiyu watched Gu Jun lying on the fMRI equipment bed. "Dr. Shen, can you explain it briefly?"In fact, Cai Zixuan doesn't know much about fMRI. There are too many detailed fields in modern medicine. He doesn't specialize in neurology. He doesn't even know about it.

Because he was on holiday today, he accompanied his old friends to come over for examination. He also wanted to study and read some literature to understand it.

"That is to say." Dr. Shen thought for a while and tried to use plain language to say: "if the nerve activity of any brain area in the brain is enhanced, the blood flow will increase, and the oxygen molecules taken will be more than the actual oxygen consumption of active neurons. Therefore, the increase of blood flow caused by neural activities will increase the blood oxygen content of corresponding brain regions, which is BOLD signal. This can help us find out where the brain is getting more nervous when he's stressed

After listening to Dr. Shen, Wu Shiyu nodded: "Oh, OK, I still don't understand."

"It is..." Dr. Shen felt that it was necessary to explain from the beginning, "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 deoxyhemoglobin, thus leading to changes in the properties of local magnetic field..."

"Dr. Shen, the more I listen to you, the more confused I am." Wu Shiyu raised his hand and interrupted, "I'll first tell you my understanding. When Xianjun does this examination, it's to shoot him when he is stressed. When he finds this position, he can judge what's wrong with him."

Cai Zixuan felt that she did not understand correctly, which was very clear.

"Almost so." But the brain is very complex

Wu Shiyu listened, thinking, because the brain is super complex, she can only understand this level.

At the same time, the equipment in the examination room began to operate, and the table carrying Gu Jun moved towards the ring magnet.
