Chapter 500 Artificial Brain!
Billion Building, Laboratory 101.
The door opened, and five people in white coats wearing masks filed in. It was Xiang Xiaotong and four new students.
As soon as the students came in, they looked around and couldn't help but open their eyes with surprise.
The laboratory is full of various instruments and equipment. The students are all academic veterans who have seen the world. No matter how sophisticated the instruments are, they have been touched and ravaged, but it is not because of the instruments that they have any reaction.
What really surprised them was...the robots!
More than a dozen humanoid robots with bright white shells stand silently next to the huge equipment. Their stylish shapes are quite eye-catching!
"The robot is a prototype made by my neuron company. Different from the clumsy robots you see elsewhere, these robots are sensitive enough to help you do experiments." Xiang Xiaotong explained.
"They can do everything from simple brushing test tubes and dispensing medicine to difficult monkey craniotomy. They may occasionally fail, but they can save you most of your time. It's like giving you a group of deputies!"
"The method of use is also simple. There is a touch screen on the back of each robot, and you just need to type commands."
Xiang Xiaotong walked behind a robot, reached out, tapped the screen, and typed a few commands on it.
The robot started instantly, picked up the empty test tubes and empty beakers in front of it, and quickly scrubbed them with quick movements!
Xiang Xiaotong picked up an empty test tube and suddenly smashed it into pieces in the pool.
The busy robot was stunned for a moment, then silently cleaned up the broken test tubes. It pinched out large pieces of glass and threw them into the trash can. It also dipped the small pieces in toilet paper, and turned on the faucet to flush away the remaining debris.
The four students were surprised and applauded!
Song He carefully observed the arm of the robot, and it turned out that it was very similar to the neuron manipulator. It was hard to tell whether the manipulator or the robot was researched first. In short, Mr. Xiang’s company seems to have hidden a lot of good things!
Xiang Xiaotong walked to the thermostatic cabinet again, opened the cabinet door, and took out a huge culture bottle.
The bottle was filled with light yellow liquid, with a jelly-like floc floating in the middle, like a piece of soaked fat.
"Your first task is to make this thing." Xiang Xiaotong knocked on the bottle, "Artificial brain!"
The students collectively stared at the teacher in shock.
Regarding the first job after the start of class, everyone imagined various possibilities, but they did not dare to think about such an incredible topic as artificial brain!
This feels like middle school students taking a physics class. The physics teacher knocks on the blackboard and says, you have mastered the basic theory of nuclear bombs, and your holiday homework is to successfully test a hydrogen bomb!
The difficulty is too ridiculous!
"Don't be nervous. It's impossible for you to make a complete and lifelike brain directly, and my teacher doesn't have that level." Xiang Xiaotong touched the culture bottle with his hand, "You observe this brain first."
The students leaned over and took a closer look at the brain tissue floating in the liquid, as if they were witnessing a miracle.
In fact, if the teacher hadn't explained it, everyone wouldn't have been able to tell that it was a brain. It was just a chaotic mass with almost no features. The only feature was a small black dot on the outside, like a mole.
"What did you find?" Xiang Xiaotong asked.
"There's a mole on it." Song He hesitated.
"What is a mole?"
Song He shook his head. He felt that it was just an inexplicable necrosis on the brain tissue, or maybe even a bunch of bacteria.
"The mole you see is an optic vesicle structure grown from this mini artificial brain." Xiang Xiaotong revealed the secret.
The students were shocked again. They have been shocked enough times today. Logically speaking, they should be tired of being shocked, but the teacher will always come up with something that breaks their imagination!
The optic vesicle structure is the precursor of the eye in the early stages of development. The structure already has the prototype of the eye, including epithelial cells, lens plate and unformed retina. It can sense certain changes in light from the outside world.
Billions of years ago, when creatures on earth first had vision, they formed this crude structure by accident.
At this moment, the culture bottle in Teacher Xiang’s hand can be said to reproduce the beginning of the road of visual evolution!
"One of the directions I'm working on is artificial vision. I have to find a way to understand the formation process of the optic nerve and visual center, so I spent a month making this thing." Xiang Xiaotong said, his eyes meeting Song He's.
Song He understood instantly. It seemed that the teacher was also thinking about Lao Zhao Fuming, and the teacher seemed to have gone further!
In comparison, the artificial cornea I made seems very childish.
"But before I had time to do it in depth, a national project came to me, and I was busy for a while, so everyone's class didn't start until today." Xiang Xiaotong continued.
"Your task is to make an artificial brain. There are several criteria. First of all, the brain tissue can survive for a long time. It is meaningless if it cannot be created and die soon after it is created."
"Secondly, like the brain I made, it must have certain functions. It doesn't have to be limited to vision, it can also have other functions. This proves that your brain is an organ that can process external information, rather than a bunch of incompetent functions. A group of communicating cells!”
"The more obvious and outstanding the function, the more credits will be given to you! If you accumulate 100 credits, you can graduate from me!"
"Each person has an independent laboratory and conducts experiments with his or her robot assistant. Hu Xiaotian Laboratory 101, Huang Qiqin Laboratory 102, Li Zhengye Laboratory 103, and Song He Laboratory 104!"
Xiang Xiaotong said, walked to the side of the test bench, bent down and pulled out a cardboard box.
Open it, it's full of paper documents.
"Here is the complete process and all the data I used to build this artificial brain. You can only see it in the laboratory and cannot spread it outside. This is also part of the confidentiality agreement."
"You can learn from my approach, but you can't copy it. If you copy a brain that is exactly the same as mine, there will be no credits!"
"I will go from lab to lab to see how you are doing. Don't let me catch you slacking off!"
"Okay, any questions?" Xiang Xiaotong looked at the students.
The students shook their heads. The teacher made it clear enough.
"Then go to work!" Xiang Xiaotong smiled slightly, "We have a regular meeting every Saturday. The students with the best grades will be generously rewarded, and the students with the worst grades will be severely punished!"
The students dispersed in a hurry and went to find the laboratory.
Song He hurried out, ran forward, came to his 104 laboratory, and entered by swiping his face.
Sure enough, there was a box of documents under the experimental table. He sat down and flipped through it, studying page by page quickly!
Soon, he figured out the teacher's general process for making an artificial brain.
The raw material is induced pluripotent stem cells, which are no longer rare. Many laboratories can make them, and there are even channels where you can buy them ready-made at a very cheap price.
First, control the density of stem cells, and after observing the expansion of neuroectoderm, add retinol acetate for culture...
After the brain tissue size increases, immunofluorescence staining is used to find vision-related genes, and then spontaneous action potentials are detected from gene-dense areas...
"I thought it was so awesome, but the technical content is not very high?" Song He flipped through the documents and muttered to himself, "The operation is quite stupid."
"You brat, who are you calling a fool?" A voice suddenly sounded from behind.
