Chapter 502 The First Acceptance Homework!
The teacher's requirements were not high, so Song He decided not to use the black technology blueprint for the time being and to do it step by step.
The east wall of the lab was empty and he had chosen it as his new data wall.
The robots operated the instruments according to the instructions. The instruments hummed and spit out pieces of data paper. Song He quickly cut and integrated the data papers, retaining the key points, and neatly pasted them on the data wall.
There are more and more papers on the walls, and more and more transparent culture tanks in the laboratory!
On the first day, 28 jars and data sheets took up one-tenth of the wall.
The next day, Song He became more and more proficient in the operation, the number of jars increased to 67, and the data paper climbed to one-fifth of the wall.
On the third day, the number of cans increased to 130, and the data paper already covered half of the wall!
In the next two days, the number of cans did not continue to increase. Although there was robot assistance, the robot could only perform some fool-proof operations. Song He could serve more than a hundred cans at the same time alone.
He felt like an oviparous animal. He groaned and laid more than a hundred eggs. Each egg was pregnant with a little life. The white brain tissue grew in the egg liquid at a speed visible to the naked eye, like an evil monster. Alien embryo.
Occasionally, a lump of artificial brain tissue dies, and Song He will sadly take out the body, observe and analyze it, and then dispose of it, feeling as sad as if a baby had died young. Of course, when he encounters brain tissue that is growing gratifyingly, he will also imagine that this child will have a future when he grows up.
The data paper has been changing drastically. From time to time, he would take off some useless data paper from the wall, throw it into the shredder, and then paste the new paper on the wall one by one.
The entire wall is like a huge skin. Old skin flakes are constantly falling off, and new skin is growing on it. It is updated all the time, and ever-changing data flows on it, like unique fingerprints.
Xiang Xiaotong occasionally comes around and always stands in front of the data wall for a few minutes, silently observing the students' test papers like an invigilator.
She was still the kind of invigilator who would collude with students. She would occasionally sneer, raise her hand to knock on a piece of paper on the wall, and leave without saying a word.
Song He went over to look at the paper, often finding flaws in the data or key changes that he hadn't noticed.
Finally, the first weekly meeting!
At eight o'clock in the evening, Song He hurried to the 201 laboratory upstairs with a culture tank in his arms.
The jar was covered with a piece of red cloth, like an ancient wine jar, wrapping the jar mysteriously.
He pushed the door open and walked in. All his classmates were already here, each holding a jar and sitting at the table. Everyone's jars were covered with cloths of different colors. The painting style looked like envoys sent by foreign countries to present treasures to the emperor.
"Everyone is here, let's have a meeting." Xiang Xiaotong said.
Song He quickly sat down at the table and listened attentively with other students.
"The reward and punishment standard for this regular meeting is that the first place with the best results will be awarded 5 credits, the last place will be deducted 5 credits, and the scores of the middle students will remain unchanged!" Xiang Xiaotong announced.
"Each classmate has brought the best sample. I will give a lecture one by one later. You can talk about anything, but you must highlight your work and earn points from me!"
"Hu Xiaotian shows off! Huang Qiqin prepares!" Xiang Xiaotong called his name.
Hu Xiaotian's plump body stood up suddenly, placed the culture jar he brought on the table, and lifted the black cloth.
The sight in the jar made the students slightly startled.
A lump of turbid brain tissue floated in the culture medium, with an electronic component running through the middle. An LED indicator light was installed on the simple green circuit board, which was flashing red light with a slow frequency, like a deep breath.
"I used the idea of brain-computer interface to combine brain tissue and electronic components!"
"The electrical signal from the electronic component will be transmitted to the brain tissue, and the brain tissue will respond, and then the bioelectricity will be transmitted back to the component, causing the indicator light to flash!" Hu Xiaotian explained.
"I want to make a brain tissue calculator that can use this bunch of brain cells to perform simple four arithmetic operations, but it has not been successful yet. At the moment, it can only judge 0 and 1."
Hu Xiaotian took out a small remote control and pointed it at the culture tank and pressed it.
I pressed the 1 button first, and the indicator light of the electronic component in the culture medium flashed at high frequency for several times. I pressed the 0 button again, but the indicator light showed no response.
"The specific principle is that the currents are different. If the current of 1 is larger, the brain tissue will respond. If the current of 0 is smaller, the brain tissue will not respond. Next, I plan to build a brain tissue circuit through current gradient and let it complete simple addition and subtraction. After calculation, it is estimated that it will be realized in two or three weeks!"
Hu Xiaotian talked endlessly and talked about a lot of specific methods. Although the current effect is average, it is only the first week after all. It can grow brain tissue and has the initial fool function, which is already very impressive!
Song He secretly sighed that there was no one who could pass the examination under Teacher Xiang's command. Hu Xiaotian, the best among his classmates, had such outstanding results!
The students applauded one after another, but Xiang Xiaotong didn't react at all. He just looked at the indicator light in the culture tank with an expressionless face.
"Huang Qiqin shows off! Li Zhengye is ready!" she said.
The tall girl with a square face stood up suddenly, placed the culture jar on the table, and lifted the white cover.
There was an uproar immediately, the students looked horrified, and Song He couldn't help but cry out.
A lump of brain tissue was floating in the culture fluid and looked normal.
What's abnormal is that there is a... little ear on the edge of the brain tissue!
The ears are only about the size of a thumb, but they have obvious auricular connective tissue and a winding external auditory canal, which is inserted into a lump of brain tissue. The sight is quite strange.
Huang Qiqin spoke at the same machine-gun speed as always:
"I cultured the brain tissue and ears separately. The ears were formed from poorly differentiated cells selected from macaque monkeys. After the ears were formed, they were combined with the brain tissue and the genes were repeatedly modified to improve fusion..."
"The problem now is that the success rate is too low. I made 120 cans, 110 of which were broken due to rejection, and eight cans could not be fused together from beginning to end. Only two cans were barely successful, and these two cans If it continues to grow, it will also face severe rejection..."
"Currently, this piece of brain tissue can hear subtle sounds and produce complex brain waves. Please come with me, students, to watch the demonstration..."
After Huang Qiqin finished speaking like a submachine gun, she picked up the jar and ran to the instrument to operate it.
The students stood up one after another and leaned over to look at the instrument screen curiously.
A scan of the entire brain tissue was displayed on the screen, and some formed circuits could be vaguely seen, most of which were concentrated toward the ears.
Huang Qiqin took out her mobile phone, randomly found a symphony, and turned up the volume!
A magical sight appears!
As the melody changes, the brain tissue becomes active, the secretion of neurotransmitters accelerates, and you seem to hear the sound of music!
The students applauded one after another and praised him for being awesome. Such a result can be achieved in just one week. His strength is so terrifying!
Xiang Xiaotong finally nodded slightly, "Yes, we can make an artificial brain and let it listen to music, but the next difficulty is to make this ear-brain survive. As long as it can survive to the end and its structure is stable, it will be a great result. !”
Huang Qiqin nodded, her face concealing worry, "Teacher, you are right. It is indeed difficult for the ear and brain to survive. The activity of this ear is not as good as yesterday, but teacher, I will try my best to keep it alive!"
"Li Zhengye shows off!" Xiang Xiaotong called, "Song He is ready!"
Li Zhengye stared at the screen for a long time, his big head seemed overwhelmed and he was turning his neck. When he heard the call, he immediately lifted the blue cloth on the culture tank.
The classmates made a louder uproar, and Song He's eyes went straight!
