Chapter Eighty-Nine: The Avengers of the Sixth Day
If we do not take into account ethics and morality, as well as the sense of the sacredness of flesh and blood since ancient times, and remove all these external factors, then the so-called brain is nothing more than a computer composed of proteins, integrating controllers, memories and combinators, the five senses are human input devices, and words and deeds are our outputs.

-- Of course, if we compare it to a computer, then the human brain is a computer with a non-von Neumann structure.
The brain records information – both from the outside world and from within the brain that has been processed – to form memories.
However, any form of movement is interactive, and when the brain records information, the structure of the brain itself changes accordingly, which can be seen as traces of memory.
Neurons are the basic building blocks of the brain, and the brain is divided into multiple functional areas, and different functional areas are networked with each other to form a functional network, which is the basic operating principle of the human brain.
Memory, on the other hand, can have an impact on the structure of the brain.
Taking rats as an example, the rats were trained to combine high-frequency or low-frequency sounds with left-to-right movements, and found the distribution of different sound frequencies in the striatum on the brain slices, as well as the areas where the striatum controls left-to-right movements.
The rat first listens to a specific frequency of sound and then decides to poke its head into the left or right hole. If its choice is correct, it is rewarded with some water (the rat has been water-restricted for some time before that). For example, if the rat is asked to associate a high-frequency sound with the left aperture (the high-frequency sound left side task), then once the rat hears a high-frequency sound, it has to poke its head into the left hole to get water to drink, and if it reaches the right hole, it will find nothing; Conversely, if the rat hears a low-frequency sound, the rat has to get water from the hole on the right.
This kind of task is a piece of cake for the rats. With only about 10 training sessions, the vast majority of rats will be rewarded with a near-100% success rate by reaching out to the correct hole after a specific frequency of sound sounds. When they were successful in their studies, the rats gave their lives – taking their brains and comparing them with those of untrained or half-trained rats to see how their brains had changed during that time of training.
There is a connection between the functional areas of the brain's "auditory cortex" and "striatum", which can be called "cortical striatum plasticity". The striatum plays an important role in cognitive behaviors, such as choice of action, concentration, and reinforcement learning. Anatomically, the striatum receives most of the projections from the cerebral cortex and directly controls and influences movement through projections to other basal nuclei downstream.
Between the perceptual information region (cerebral cortex) and the motor information region (basal nucleus), the plasticity of the striatum is likely to be one of the mechanisms of reinforcement learning.
So it is hypothesized that the synapses projected by the auditory cortex to the striatum may have produced changes in learning, and that this change may have recorded the learned memory.
So, what exactly do these learned memories do to the brain?
The biggest difference between the brain and the computer is that the brain is a "living" thing - if there is a certain circuit in the brain that is used very frequently, then this circuit will become more and more efficient, which forms the basis of human learning and memory.
Using optogenetic technology and electrophysiological technology, the intensity of nerve signals projected by the auditory cortex to the striatum was detected, and sure enough, it was found that with the training of rats, some lines from the auditory cortex to the striatum were also strengthened. For example, in rats that have undergone high-frequency left-sided tasks, the neural connections between the areas of the auditory cortex that process high-frequency sounds and the areas of the striatum that are relevant to left-side decision-making become stronger. Conversely, if the rat was trained on other tasks, there was no change in this route.
For other aspects of learning and memory, if the corresponding anatomical coordinates can be found, then it is also feasible to read the traces of memory in the brain, and then deduce the memory content from the traces stored in the brain structure.
This means --
"The brain after death will reveal the secrets of life......"
Looking at the cultivation cabin in front of him, Li You smiled with satisfaction.
"A dead brain, scan its structure, and derive the memory content in reverse according to the memory traces left by each functional area of the brain structure......"
The brain quantum waves sensed the brain waves of the little girl inside who became more and more irritable, angry, fearful, and desperate, and Li You's smile became higher and higher.
"And by simulating brain currents, reconstructing the brain's weak current impulse network, and extracting information from this network......"
Through tempered glass and orange-yellow artificial amniotic fluid, Li You extended a helping hand to this little girl who was trapped in a nightmare.
"Although the process of translating memories will inevitably be accompanied by distortion, loss, ambiguity, and errors in information, in general, one thing can still be ......."
Li Youna's seemingly endless brain quantum waves surged, like a warm big hand, gradually smoothing the little girl's brain waves, irritability returned to calm, anger returned to purity, fear returned to peace, despair returned to tranquility.
"Reading the memories of the deceased and transferring them to a replica made from the genetic information of the deceased, and realizing the resurrection of the dead in disguise, is the greatest delusion and ambition ......of human beings for 10,000 years."
Under the eyelids, the little girl's eyeballs are rhythming rapidly, her brain is becoming more and more active, and in the "perspective" of Li You's quantum senses, the quantum glow of her brain is igniting.
This is greatness, not a miracle. For this great power comes from the hands of men, not from ethereal gods......"
As the musculature contracted throughout her body, her lungs spat out a large amount of foam in the squeezing, enveloping her face and floating upward.
"In the name of science and technology, wake up......"
She opened her mouth and spat out the last bubble and let out her first moan.
"The first credible resurrection from the dead in human history......"
She opened her eyes, and there was a quantum glow in them, brilliant as gold.
"Iskra Zoya!"
In her eyes, Li You's figure was reflected.
