The matter between Anton and Mimi is settled. Qi Min came to the lab a little later than usual, and the three doctoral students had already gone to do the experiment.

She originally wanted to find Ke Li in the clean room, but she also thought that Ke Li might be in the animal room, and it was really boring to wait in the clean room and not be able to play with her mobile phone. So Qi Min sat in his own position in the laboratory and opened Jupyter to take a look at the code running, there was still no problem, and it was expected that it might be completed in another week or two.

At present, the machine learning method has been used to verify that the positive result has been very stable, but the fluctuation is not explained for the time being. Previously, researcher Zhou Xiaoshan suggested that she could publish a small article to test the waters, which attracted widespread attention and then posted the full-size brain-like article.

This is the routine of the academic community to make big news, but Qi Min doesn't dare to do it. She is going to point to this article to eat, in case the full-size brain-like body runs out and finds that the performance is not much different from 256×256×256, then the second article will lose its originality, and the impact factor may not even be as good as the first article. Anyway, the assessment is based on the impact factor, so she might as well wait until the full-scale brain-like body is made immediately before publishing the article, so that the experimental data and theoretical models during her doctoral studies can be applied to the brain-like body later, such a complete logical chain, even if she can't make any big news, she has to give some hard points, right?

Qi Min was thinking about it when he suddenly heard footsteps outside the door. The door to the laboratory was usually open, and she turned her head to see that it was Ke Li who had come over with the cage of the rat.

Ke Li walked to the door of the laboratory and glanced inside, and when he saw Qi Min, he immediately said, "Hey, you see that these rats really have nothing to do." ”

Qi Min got up from his seat and walked over quickly, and saw that although the rats in the experimental group in the cage had electrodes inserted in their heads, they were still eating like ordinary rats, and some were crawling around. It seems that the miniature callosum interface invented by the research group of the École Supérieure de Paris is quite reliable.

"How do the metabolic data look?" Qi Min asked.

"I just sent it to the network disk, and I haven't seen it yet." Ke Li said, "I'm going to take them to make a water maze now." ”

"Then I'll go with you?" Qi Min proposed.

Ke Li looked at her and asked with some embarrassment, "Have you ever done a water maze test before?" ”

Qi Min shook his head hesitantly. She is a neurophysiology student, and she is still a little far from memory learning. In the past, there were a small number of validation experiments in memory learning, but they were usually outsourced to companies. Now she doesn't have so much money to lead the group by herself, and this time she has to do the water maze several times, so she has to do it by herself in the group.

"That'...... I'd better go on my own. Ke Li smiled a little embarrassedly and said, "It's okay, there are technicians on the animal platform who can help." ”

He obviously thought that Qi Min was not good for animal experiments. Qi Min had to admit this, and as a PI, she really didn't need to follow all the experiments, so she had to say: "You go by yourself, I'll analyze the metabolic data first." Do you want to bring food for lunch? ”

Ke Li thought for a while and said, "Just bring some." ”

The use of metabolic cages for metabolic monitoring of rats is actually a bit expensive, in the animal room of the Chinese University of Technology, the rent of an imported metabolic cage plus consumables and so on cost more than a thousand. However, due to the small number of rats used by Qi Min for brain-computer interface, he can afford to keep them in a metabolic cage all the time.

The benefit of comprehensive metabolic monitoring is that it is very credible to assess the impact of the installation of the corpus callosum interface in rats. However, Qi Min did not see a significant difference in the metabolic data of the rats installed with brain-computer interfaces and the blank control group rats that underwent sham surgery, and the rank sum test also showed that there was no significant difference. This result can be regarded as supporting the previous article published by the research group of the Ecole Supérieure de Paris.

So it seems that this brain-computer interface should be available. If the callosum interface does not affect the memory and learning ability of rats, then the subsequent experiments will be easy to carry out.

Qi Min's idea of animal experiments is actually very simple. She had suspected that the fluctuations in the 256×256×256 brain body were analogues of some kind of consciousness, so she wanted to connect it to the animal's brain to see if it would affect its memory and learning function.

Because the corpus callosum interface does not address the demodulation of neuronal signals in the brain, there is no way to implement more complex experiments. But if it can be proved that the connected brain-like body does have an impact on animal behavior, it can also attract some attention in the industry if it is written into the article and packaged it a little.

At noon, Qi Min, Wang Xin, and Chen Linyou went to the canteen to eat together, but they didn't expect it to rain heavily outside, and Wang Xin didn't dare to ride a bicycle while holding an umbrella, so the three of them walked.

Walk down the road and talk about recent experiments. Because Qi Min was on Ke Li's side, he didn't care too much about Wang Xin and Chen Linyou. Take advantage of the lunch to eat together to understand their progress, and urge them by the way.

WALKING ON THE STAIRS OF THE CAFETERIA, QI MIN WAS LISTENING TO CHEN LINYOU TALK ABOUT THE PROBLEMS HE ENCOUNTERED WHEN HE DID NEUROORGANIOD, AND SOMEONE NEXT TO HIM GREETED HER: "HEY, QI MIN?" ”

Qi Min reflexively turned around and found that it was Zhang Zhiyong, followed by two young men who should be doctoral students in his laboratory. She usually doesn't communicate much with the chemistry department, but Zhang Zhi helped her order takeout when she was on a business trip together, so she is a little more familiar with her than ordinary colleagues.

"Zhiyong, how do you come out to eat?" Qi Min greeted.

"yes...... Just go out for a meal and catch the rain. Zhang Zhiyong smiled at her, perhaps because he was amused by the fellow PI who took the doctoral students out to dinner.

BUT FOR QI MIN, ZHANG ZHIYONG IS A GREAT GOD OF SCIENCE FOR THE TOPIC OF STUDYING FOR A DOCTORATE, AND SHE IS STILL INCOMPARABLE TO THE WASTE WOOD THAT GRADUATED FROM THE ARTICLE. The young talents in the scientific research circle are close to the doctoral students, which is called approachable, and the ordinary water PI takes the doctoral students to eat, drink and have fun, which is called not doing their jobs.

However, Qi Min saw that the two young men with Zhang Zhiyong were crowded under an umbrella, and still took the initiative to hand over her extra umbrella: "I have an extra umbrella here, let's lend it to you first." ”

"Thank you." Zhang Zhiyong took the umbrella and opened it, and returned the umbrella in his hand, which should be one of the doctoral students, "I'll return it to you before I get off work." ”

This can be regarded as repaying the favor of people who helped to make the phone at the beginning. Qi Min thought that he still had to communicate more with the gods, so it was unrealistic to talk to the real boss about her experience of almost not graduating, but it was easier to get acquainted with the future boss by virtue of the common denominator of the young PI.
