Chapter 548 Neuronal Networks (2)
Chapter 548 Neuron Network ([-])
After pondering for a moment, Zhou Xing suddenly reached out and touched the holographic screen, called up the holographic design software, and started to build the network model.
The virtual model on the holographic screen is constantly changing in Zhou Xing's hands, presenting a complex and sophisticated model map, as if the bright starry sky is linked into a network.
In the laboratory command center, Zhou Xing was busy with concentration, and the structure of the virtual model became more and more complicated.
As time passed bit by bit, the scientists gradually discovered this situation, and they gathered around one after another.
"What kind of model is this? The structure is so complicated!"
"The model looks like the neural network of the human brain, but the material is so strange, and the medium structure is not like biological cells."
"The medium point of the model is a bit like a photon cluster. What kind of model is this?"
"The structure is too complicated. With so many connection points, the energy band effect produced by frequency light waves is used. Can this model be established in the end?"
"..."
The scientists surrounding Zhou Xing began to discuss in low voices. They were confused by Zhou Xing's design model, and most of them couldn't understand the purpose of the model he designed.
However, they surrounded Zhou Xing and were still unwilling to leave.
After so many years, now, Zhou Xing is more like a conductor in the field of science. From the experimental command center, he remotely commands scientists all over the world to launch an "attack" on a breakthrough point in a certain field of science. It's time for a 'battle'.
At this time, Zhou Xing built a project model by himself, which immediately aroused the strong curiosity of the scientists.
In a blink of an eye, two hours passed.
Zhou Xing stopped his frequently moving hands, and a smile appeared on his tired face.
"Xiaozhi deduces this designable plan and confirms the result." Zhou Xing gave Zhou Xiaozhi an order.
"Okay, boss!" Zhou Xiaozhi readily complied, and immediately, as soon as the holographic screen changed, a complex deduction and calculation began on Zhou Xing's design plan.
The dots of silver light in the holographic screen danced crazily, and the silver light flickered in the veins, making it dizzying to see.
"Mr. Zhou, what model is this? A neuron network?" Professor Lin Hai looked at Zhou Xing and asked uncertainly.
Zhou Xing turned his head to look at Professor Lin Hai, and nodded with a smile: "That's right, it's a neuron network."
Hearing this, Professor Lin Hai was shocked and asked excitedly, "Mr. Zhou, are you designing a biological computer?"
Neural networks are standard equipment for biological computers.
Biocomputer is also called biomimetic computer. Its main raw material is protein molecule produced by bioengineering technology, which is used as biochip to replace semiconductor silicon chip, and uses organic compounds to store data.
The information of the biological computer propagates in the form of waves. When the wave propagates along the protein molecular chain, it will cause the change of the single bond and double bond structure sequence in the protein molecular chain. It has strong anti-electromagnetic interference ability and can completely eliminate the circuit The interference between them, the energy consumption is one billionth of that of ordinary computers, and it has huge storage capacity. Biological computers have many characteristics of living organisms, can exert the biological adjustment function, automatically repair the faults that occur on the chip, and can imitate The working mechanism of the human brain, ….
Today, when photonic computers are popular, with many advantages, biological computers still occupy a certain position.
As soon as Professor Lin Hai's words fell, Professor Verus immediately retorted: "No, it's not a biological computer. This model does not use biological materials, and a biological computer cannot be established."
Hearing this, the professors looked at the model on the holographic screen, Qi Qi fell silent.
A biological computer that simulates a neuron network must be established to completely simulate the operation of a neuron network, which is a complex biological activity. The small amount of materials used in the model absolutely cannot simulate this system.
Neuronal network activity is an extremely complex process.
Neurons, also known as nerve cells, are the basic units that constitute the structure and function of the nervous system. They have long synaptic (axon) cells, which are composed of cell bodies and cell processes, and a sheath is placed on the long axons. Nerve fibers, the small branches at the end are called nerve endings, there are plaque-like extranuclear chromatin in the neuron cytoplasm, and many neuron fibers, the elongated part of the systemic process extending from the cell body, which can be divided into dendrites And the axon, each neuron can have one or more dendrites, which can receive stimuli and transmit the excitation to the cell body.
There is a sensitive and excitable membrane on the outer surface of nerve cells. There are various receptors and ion channels on the membrane. The receptors on the membrane can combine with corresponding chemical neurotransmitters.When the receptor binds to the acetylcholine transmitter or the γ-aminobutyric acid transmitter, the ion permeability of the membrane and the potential difference between the inside and outside of the membrane change.
Neurofilaments, microtubules, and microfilaments, these three kinds of fibers constitute the cytoskeleton of neurons, participate in material transportation, ..., the activity of the entire neuron network is an extremely complicated process, which determines the functions of the organs and systems of the entire organism connect with each other.
Although the model in front of us is very complex, it is limited by the materials used and absolutely cannot simulate the activities of biological neuron network systems, especially this neuron network model similar to the human brain.
The activities of the human brain include: neural stem cells, excitatory neurons, inhibitory neurons, astrocytes, oligodendrocytes, microglial cells, neural networks, ..., at the same time, there are various body Cell activities and protein sequence libraries are linked, which is an extremely complex three-dimensional structure system.
The complexity of the human brain far exceeds the cognitive ability of human beings. The acquisition, processing, processing and advanced cognitive mechanisms of complex information by the human brain, the acquisition and processing of neural information, and various operating laws..., even in this interstellar era , humans still cannot understand their own brains.
"Mr. Zhou, what kind of materials are used for the neurons in the model? Photon clouds?" Professor Lin Hai retracted the guess of the biological computer, looked at Zhou Xing and asked curiously.
"It's a photonic crystal." Zhou Xing replied with a smile.
Hearing this, all the scientists were surprised.
Photonic crystals refer to artificial periodic dielectric structures with photonic bandgap characteristics, sometimes called PBG photonic crystal structures. Photonic bandgap means that waves in a certain frequency range cannot propagate in this periodic structure, that is, the structure itself There is a "forbidden band".
Photonic crystals are artificial microstructures that are periodically arranged by media with different refractive indices. Photonic crystals are photonic band gap materials. From the perspective of material structure, photonic crystals are a type of artificial microstructure with periodic dielectric structures on the optical scale. Crystals designed and manufactured.
From the perspective of material structure, photonic crystals are a type of artificially designed and manufactured crystals with periodic dielectric structures on the optical scale. Similar to the modulation of electron wave functions by semiconductor lattices, photonic band gap materials can modulate the When the electromagnetic wave of the wavelength propagates in the photonic bandgap material, it is modulated due to the Bragg scattering, and the energy of the electromagnetic wave forms an energy band structure.
Simply put, photonic crystals have the function of wavelength selection, which can selectively pass light of a certain wavelength band or prevent light of other wavelengths from passing through. According to the characteristics of this material, yes, this material can produce more diverse Variety.
However, can photonic crystal materials meet the needs of neuron network models?This model cannot be established!
All of a sudden, the scientists showed puzzled expressions on their faces.
"Mr. Zhou, do you plan to use this material to simulate a neuron network?" Professor Verus looked at Zhou Xing and asked.
"Isn't this superfluous! To build a neuron network, protein molecular materials must be used!" Professor Malos frowned and asked strangely.
"Yes! How can the neuron network not use biological materials?" Professor Lin Hai raised his eyes and said inexplicably.
All the professors looked at Zhou Xing together, their eyes full of doubts.
Neural networks are the standard equipment for biological computers. Similarly, protein molecular materials are standard equipment for refining biochips, and there is no other material that can compare with them.
Zhou Xing looked at the crowd and sighed: "Let's watch Xiaozhi's deduction first! If this design model can't be successful, it's useless for me to explain more."
"How come, Mr. Zhou, you must have a reason for doing this!"
"This is the model you designed, it must be a success!"
"Yeah! I think so too."
"..."
Seeing this design model, the professors made their own judgments, but in front of Zhou Xing, a genius scientist who is good at creating miracles, everything became difficult to say.
Zhou Xing ignored everyone's flattery, and his eyes fell on the big holographic screen, watching Zhou Xiaozhi's deduction process.
The model with silver light shining, densely packed with shining silver dots, is undergoing complex calculations and changes like a starry sky. This process is like trillions of DNA molecules undergoing chemical reactions under the action of certain biological enzymes, simultaneously producing Dozens of trillions of calculations.
……
Ten minutes passed, and the changes on the holographic screen finally stopped.
"Boss, the deduction has passed, and the implementation success rate is [-]%. However, the neuron computing network built with this kind of material cannot exceed the computing power of ten trillion times per second, and cannot replace Xiaozhi's current computing system! "Zhou Xiaozhi replied to Zhou Xing with a slightly disappointed voice.
Hearing this, Zhou Xing had an expected smile on his face, feeling very satisfied.
Hearing this, all the scientists looked at each other, and suddenly understood the purpose of Zhou Xing's design of this model.
"Mr. Zhou, you plan to update Xiaozhi's 'hardware'. In this way, don't you want to change Xiaozhi's operating mode?" Professor Lin Hai looked at Zhou Xing and asked in surprise.
"Xiaozhi needs to increase his computing power to support our development, so it won't work!" Zhou Xing smiled wryly and explained.
Hearing this, all the professors' eyes lit up. Zhou Xiaozhi is the core of the development of human civilization. Its computing power directly affects the development speed of human civilization. The sooner this matter is done, the better.
"Because biological materials can't match Xiaozhi's 'core components', the idea of neuron network is correct, but photonic crystals are not a bad choice!" Professor Li Yan thought for a moment and vetoed.
"Yes! The photonic crystal material is too simple to simulate the complex changes of the neuron network. Xiaozhi's deduction results have confirmed this problem." Professor Verus looked at the holographic screen and said.
"What about three-dimensional photonic crystal materials! Combined with nanowires and organic protein materials, it should be possible to build a qualified 'neuron cell'." Professor Lin Hai looked at Zhou Xing and suggested.
"No, organic protein ingredients cannot be integrated into the operating environment of the 'hardware system'." Zhou Xing looked at Professor Lin Hai and retorted.
Hearing this, the professors frowned, only then did they realize how difficult it is to solve this problem.
The instrument that reprinted Zhou Xiaozhi's core data is a very precise and complex device. It must operate at the extreme low temperature under the ultimate vacuum. The temperature of the operating environment of the external 'components' must not be too high. In this state , all organic organisms will lose their activity, so the materials for the calculation model will be limited to a very narrow range.
"Mr. Zhou, photonic crystals can't meet the requirements, why don't you try metamaterials?" Professor Lin Hai looked at Zhou Xing and suggested.
"Yes, for example, multi-dimensional supercrystals, which have different properties, conduction band, valence band are the same and different layers have different changes, zero band gap, and negative band gap also change,..., materials like this should be able to satisfy neuroscience. Yuan change requirements." Professor Verus looked at Zhou Xing and suggested.
Hearing this, Zhou Xing showed a thoughtful look, then shook his head.
Metamaterials, also known as metamaterials, micro-nano structures, superdielectrics, heterotropic media, artificial electromagnetic media, ..., also include photonic crystals in a broad sense, and more artificial units and artificial atoms to realize photothermoacoustics Uses such as power,
For example, a superlattice is composed of two semiconductor materials with different band gaps. Each quantum well will form a new selection rule that affects the movement of charges in this structure. They are alternated at a certain period along the Specific growth direction deposition,... The structure is sometimes called coupled multiple quantum wells. Such complex changes are still difficult to meet the needs of simulating photonic neurons.
Seeing Zhou Xing shaking his head and falling into deep thought, Professor Lin Hai sighed dejectedly: "Oh! If there is a material between living things and metals, it won't be so troublesome!"
Hearing this, the professors were silent for a while. Since the technological civilization of human civilization has developed so far, they have clearly understood the universe and are able to develop various advanced technologies and sophisticated equipment. However, many designs can only be recorded in the data. Curry, put them away.
Because of the material problem, it has become the biggest problem restricting the development of human civilization.
For example, if the neuron model designed by Zhou Xing can use suitable materials, this neuron computing model can generate an astronomical computing power, which is expected to be 10,000+ times that of Zhou Xiaozhi's current computing power.
For a while, the entire experimental command center fell into silence, and everyone was thinking about a better plan.
