MTL - Rebirth 2002: Nano Life-Chapter 9 Science is the first productive force
After dinner, Xia Yi rushed to wash the dishes, but Chen Yizhe didn't rush to do it any more. He returned to his room with the turtle he bought.
This is a pearl tortoise, also known as the Chinese flower tortoise, with a length of only about five centimeters.
Of course, Chen Yizhe bought the turtle not only to keep it as a pet, but to use it as an experimental product for a series of experiments.
Chen Yizhe said to the turtle, "Turtle, turtle, I don't know if it is your luck or misfortune to meet me. You will be called Turtle Xiaolong in the future. I hope you don't have a short life like Bruce Lee."
When Chen Yizhe was exploring his own brain, he found that the brain is indeed composed of trillions of brain cells, which is no less than the nanoworm under Chen Yizhe's control. Each brain cell is shaped like the most complex baby octopus, with a center, many branch points, and each branch has many connection points. Each brain cell can make up to 20,000 connections with other brain cells, and they pass information back and forth in a complexity unmatched in the world.
Chen Yizhe still remembered that his girlfriend's father suffered from brain hemorrhage or brain stem hemorrhage in his last life. He was rescued in ICU for three days and eventually died of brain death. In fact, the doctor was shaking his head at the beginning of the examination, and the brainstem hemorrhage could not be operated, so Chen Yizhe's girlfriend was psychologically prepared.
The mystery and danger of the brain makes Chen Yizhe keep a conservative and cautious attitude towards the modification of his nervous system, because the brain's operation is extremely complex, even if Chen Yizhe scans the structure of the entire brain, it is impossible to write down all of it. If you rashly move your brain, if something goes wrong, you fall into a coma or even turn into a vegetative state, then even if you have nanoworms, you will not be able to recover yourself. This is different from the modification of other parts of the body. The modification of Chen Yizhe himself can always be in control.
In the animal kingdom, mammals, reptiles and birds all originated from the same ancestor that lived about 320 million years ago, yet the brain has evolved to varying degrees over hundreds of millions of years of evolution. The IQ is ranked from high to low, mammals, birds, reptiles. The IQ of turtles belonging to reptiles is basically the watershed of all vertebrates. The IQ is higher than the basic basic high IQ of reptiles, and vice versa is low IQ animals.
Since humans and turtles belong to the same ancestor, it means that human brains and turtles must have something in common. Chen Yizhe controlled the nanoworm to scan the turtle's body. The digestive system of turtles is relatively simple, with tongue and throat, esophagus and stomach, and well-developed lungs, but small turtles have tight and powerful lungs. Turtles also have kidneys, accessory kidneys, bladder, accessory bladder, and ureter. The funniest thing about this little turtle is that it has a complete reproductive system, jj, gw, and vas deferens. From the naked eye, Chen Yizhe really can't find out where the turtle's JJ is hiding.
Then Chen Yizhe focused on the tortoise's nervous system. As Chen Yizhe expected, in the tortoise's nervous system, Chen Yizhe discovered the same part of the brain structure as his own. The midbrain, and the oldest basal ganglia, the globus pallidus and the olfactory bulb, are located in the lowest and deepest part of the human brain.
At the front end of the brain is the olfactory lobe. This part is also found in the human nervous system, but it may be a marginalized relationship in evolution. For example, this part of Chen Yizhe is already very small.
The ventromedial hidden in the front of the cerebral hemisphere extends to the nasal cavity, the midbrain and cerebellum are also more developed, the oblongata is connected to the spinal cord, and there are 12 pairs of cranial nerves. The overall structure is basically the same as that of humans.
Chen Yizhe has read a lot of books in his past life, among which biological mysticism and science fiction are the two most attractive to him. He once read a hypothesis, as early as the 1950s and 1960s, a scientist put forward the theory of "Trinity of the brain".
This theory divides the human brain into "reptile brain", "ancient mammalian brain" and "new mammalian brain" according to the order of appearance in evolutionary history. If this hypothesis is true, the brain in the same part of the turtle is actually a "reptile brain".
Chen Yizhe controlled the nanoworms to conduct small stimulations in various parts of the turtle's brain, and continued to analyze the main functions of various parts of the turtle's brain. For example, the brain stem and cerebellum played a controlling role in the behavior of the turtle and mainly controlled the turtle. The body's muscles, balance, and automatic functions, such as breathing and heartbeat, stop when the brainstem is stimulated. In the turtle's body, there are only the most basic and original behaviors. No matter how stimulated Chen Yizhe is, he can't feel the signals in the brain and body similar to the changes in human emotions. That is to say, the turtle can't feel joy, anger and sadness. It has no emotions. .
Emotions are very common in mammals. They are also happy, sad, excited, and afraid... And it should be the ancient mammalian brain that controls emotions.
"Alas, it's a pity that there are no mammals such as cats and dogs now. Otherwise, we can compare them again. I wonder if Teacher Xia would let me raise them!" .
However, Chen Yizhe can still roughly guess where the ancient mammal brain is. There is a cortex with a six-layer structure in the outermost part of the human brain area. This six-layer cortex is actually the left and right brains, and it is the new mammalian brain. Of particular importance to humans is the frontal lobe.
In his own brain observation, Chen Yizhe found that many signals are actually sent and terminated here. When Chen Yizhe was checking the information, he realized that the frontal lobe is the "commander-in-chief" in the human brain, which not only controls a series of high-level cognitive functions, but also inhibits some low-level centers (for example, "reptile brain") activities to prevent humans from making some inappropriate behaviors. It is no exaggeration to say that all human civilizations are built on or in the frontal lobe of the forebrain.
There is also a small three-layer cortex on the outside of the two hemispheres of the turtle's brain, which is different from Chen Yizhe's own. There is a cortex with a six-layer structure in the outermost part of his brain. This cortex is different from that of the turtle. The neurons inside are also of different types. UU reading www.uukanshu. However, the structure of the hippocampus between the thalamus and the medial temporal lobe of Chen Yizhe's brain is similar to that of Turtle Xiaolong, except that the small cortex of Turtle Xiaolong looks like a single piece of paper, while Chen Yizhe's seems to be folded.
I tried to stimulate the small cortex of the little turtle, but I haven't seen any feedback on which function is involved. Chen Yizhe estimated that the small cortex should not be an instinctive stress response of the body, let alone emotions. What is it? , it is estimated that the experimental analysis will take more time.
Buying a turtle and returning to do research has deepened Chen Yizhe's understanding of his brain, and it also made him have a bit of fantasy in his heart. He thoroughly studied the turtle's body and nervous system, and then tried to transform and brain, or In the future, a chip will be implanted directly in the brain of the turtle Xiaolong.
As mentioned above, control and energy are now two important factors that limit Chen Yizhe's transformation of nanoworms in the microscopic world. Chen Yizhe already has a rough plan in mind. The first plan is to directly transform the heart and brain as the source of energy for the brain; the other plan is to implant energy devices that can be converted into biological energy in the body and implant them in the brain. Chips with super computing power.
However, whether it is the former or the latter, Chen Yizhe needs to have top-notch knowledge of mathematics, biochemistry, physics, etc. At this moment, Chen Yizhe feels that his knowledge is shallow. Just like a scientist said, the more you study the world, the more you will Find yourself smaller and smaller.
There are many things that are not imagined out of thin air. If Chen Yizhe does not know the microstructure of gold, no matter how strong his control and energy are, he does not know how to transform it.
The great man said it well, science is the primary productive force!
"It seems that I still have to study hard and make progress every day!" Chen Yizhe thought helplessly.
