Plague Doctor

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

After entering the plain building, they came to an advanced brain function research lab on the fifth floor, where Dr. Shen was waiting, as well as Professor Ma Jun, who was in charge of the lab, and researchers. Professor Ma is one of the best brain scientists in the country and is now part of Gu Jun's treatment team.

Gu Jun's brain is in an abnormal state. He does not have ordinary mental disorders. There is no such thing as anxiety, depression, transcendence, delirium, etc. His personality has not changed.

But when he comes into contact with “unusual” and “supernatural forces” - including ancestors, fantasy dreams, spells, illusions, aliens, Lalaire, etc. - he experiences headache symptoms, and exposure includes listening to others, thinking, and engaging in action.

Hearing someone talk is the lightest symptom, if he just listens and doesn't think, it's just a headache; but once he hears it in his brain and thinks about it himself, the symptoms rapidly worsen and he has a strong fissure in his brain; it's much worse if he's involved personally.

But regardless of the severity of the symptoms, when he interrupts contact, his headache slowly subsides. If you don't touch it, nothing will happen.

The longer you are exposed to the opposite, the more aggravated the pain, the more painful it can be to develop general tone and convulsion symptoms of epilepsy, and transient syncope.

Three days ago, Gu Jun was only reading a GOA file sent by Grandpa Tong. After reading less than two pages, he twitched and fainted. He really scared the people around him. Fortunately, the paramedics were just about to start first-aid, and he slowly woke up.

After that, the health care workers got depressed again, and everyone knew there was a big problem.

Gu Jun also knew that he was not optimistic. Just a moment, his spiritual consumption was deep, he was tired and sad, and slowed down for a day.

The human brain is too complex, and his brain is longer than a tumor, lacks oxygen, has been injured, and has undergone surgery. And the injured bleeding site is the right anterior frontal lobe, and the cerebral lobe leukectomy damages the anterior frontal lobe region, which is very difficult to tell.

It is evident that his situation is similar to that of post-traumatic stress disorder (PTSD), and that "abnormal things” are his source of stress.

Jack Wells had PTSD symptoms back then, and survivors from some other countries in the coalition also had mild PTSD symptoms this time.

Unlike them, however, Gu Jun did not have typical clinical manifestations of PTSD, no invasive traumatic recurrence, no negative changes in cognition and mood, no excessive vigilance, prone to irritability, etc., nor did he have psychological difficulties in self-assessment in this regard, and did not want to avoid the memory of those events.

However, his brain showed strong evasion when something similar or related to stress appeared, and when confronted or exposed, there was no psychological pain, but a strong physiological response, which was consistent with the PTSD diagnosis.

In the case of Gu Jun, the senior staff at headquarters were very nervous, as were Grandpa Tong and Yao Shinian.

In personal relations, Grandpa Tong did not want to see Gu Jun like this; for the sake of the big picture, they did not want Gu Jun to no longer be able to touch the anomaly. In the last two years, Gu Jun's contribution and role need not be said, if he can't be cured back, it means he can only rest for a long time and even retire...

So for NASA, it's a huge loss for the global public.

It is precisely for this reason that the treatment team is once again heavily responsible. Liu Mingfeng and others who cure the body have left, while Professor Malin and others who study the brain take on the heavy burden.

Their first task is to find out the pathological mechanism. Whether this is just Gu Jun's psychological problem or whether his brain is damaged or dysfunctional, this is why this is happening.

Gu Jun has tried to use old stamp purified fossils before, and no mental erosion has been detected. He hasn't done an S-value test yet, Dr. Shen, and they're worried that the impact of the trauma scene could lead him back into a coma, which would only make the situation more difficult.

At this time, Gu Jun, Wu Shiyu and Cai Zixuan walked into the lab, where advanced equipment could do some more detailed brain examinations for him.

The lab is bright and spacious, divided into anterior chambers, which are connected to several laboratories with different equipment.

After everyone greeted him, Professor Gu Jun and others took him to the FMRI examination room. FMRI is a functional magnetic resonance imaging device that looks similar to a nuclear magnetic resonance, but does not require injection of radioactive material when detected. His test is BOLD-FMRI, which relies on functional MRI imaging for blood oxygen levels.

“This is a functional neuroimaging method.” Dr. Shen explained to Wu Shiyu that “the examination will allow Arjun to complete the stimulation task, reflecting local brain activity by measuring the signal changes on which his blood oxygen level depends, this precise positioning can help diagnose his pathological mechanisms. ”

“I don't understand.” Wu Shiyu looked at Gu Jun lying on the bed of the FMRI equipment through the glass window in the examination room, "Dr. Shen, can you explain briefly? ”

In fact, Cai Zixuan doesn't really know much about FMRI. Modern medicine really has too many fields of refinement, not specializing in neurology, and he hasn't even heard of these.

He still came to check with his old friend because he was on vacation today. He also wanted to study and read some of the literature to understand.

“That is.” Dr. Shen thought about it and tried to preach in plain language: "If the neurological activity in any part of the brain increases, the blood flow will increase, and the oxygen molecule will be taken more than the actual oxygen consumption of the active neuron, so the increase in blood flow due to neurological activity will increase the blood oxygen content of the corresponding brain area, which is the BOLD signal. This helps us to identify where the nerve activity in the brain has increased when he stresses. ”

After listening to Dr. Shen, Wu Shiyu nodded his head: "Oh well, I still don't understand. ”

“It is…” Dr. Shen felt it necessary to go over it from the beginning. “The BOLD signal is the difference in the degree to which neuronal activity affects local oxygen consumption and cerebral blood flow, which changes the relative content of local deoxyhemoglobin, leading to a change in the properties of local magnetic fields...”

“Dr. Shen, the more I seem to listen to you, the more confused.” Wu Shiyu lifted his hand to interrupt, “I said first of all my understanding, Xian Jun did this test, was to photograph what was exciting in his brain when he was stressed, find this position before judging what was wrong with him. ”

Cai Zixuan thought she understood correctly, and said it clearly.

“Almost.” Dr. Shen said, "But the brain is very complex...”

Wu Shiyu listened and thought, just because her brain is super complicated, she can only understand this level.

Meanwhile, the equipment inside the examination room began to run. In the sound of the noise, Gu Jun's patient table was moved towards the circular ring magnet.
