So, regarding the question of neural network Darwinism 🧠. You should understand that, essentially, the human brain represents a kind of broad neural network controller. It organizes groups of neurons into layers, and these layers, interacting with each other, form synapses. It is precisely the synapses that determine how generalization will operate.
According to various sources, a single neuron is capable of forming from 10,000 to 60,000 connections. Both numbers are certainly impressive. Through these synaptic connections, neurons perform signal generalization.
From an evolutionary perspective, we as a neural organism have gone further. The peculiarity of our neural system is that we use as the primary unit not so much the neurons themselves as the synapses. Synaptic connections become the key reference point.
From this arises a problem that can be called the problem of neural network Darwinism 🧬. It lies in the fact that we begin to depend on the synaptic connections that are formed. Thus, our nervous system in some sense continues to evolve, but without full control on our part.
The process of neural network Darwinism leads to neurons constantly restructuring synaptic structures by changing their connections. As a result, functions may either strengthen or weaken.
From here arises an important problem of modern medicine 🧪. When we talk about cell therapy, for example the transplantation of stem cells as a method of recovery after neural injuries, a fundamental limitation appears. The issue is not only — and not even primarily — the restoration of the neurons themselves. The problem lies in restoring their synapses, that is, the plasticity of synaptic connections, a fully developed technology for which essentially does not yet exist.
The key difficulty is that cell transplantation alone does not solve the problem. What is required is the modification of synaptic plasticity — their ability to reorganize, adapt, and support new functions. This remains one of the main challenges of modern neurotherapy.
From here also arises the problem of remyelination.
The central nervous system contains cells that are capable of migrating, integrating into neuron axons, and forming a myelin sheath around them. However, neural network Darwinism leads to the fact that this process is not always triggered.
For oligodendrocyte precursor cells, the key problem is the need to receive a stimulus signal ⚡. A cell will not simply migrate, attach to a neuron, and form myelin on its own. If the neuron is not functioning, from the system’s perspective the restoration becomes biologically “unprofitable.” And a demyelinated neuron quite often indeed stops functioning.
As a result, the migration of oligodendrocyte precursor cells and their attachment to the neuron does not occur. This, in turn, triggers the process of secondary neurodegeneration.
A cascade of neurodegenerative processes emerges: myelin is not restored, neurons gradually lose their function, and the organism is unable to fully compensate for this loss.
This is where the idea of stimulation — both physical and chemical — appears, which can play an important role in diseases associated with myelin damage.
For example, a patient who has suffered a neural injury must constantly perform a wide range of physical exercises 🏃. The point is that in demyelinating lesions, even if precursor cells are present, their migration may not occur without appropriate stimuli. One of the key stimuli is physical activity.
Therefore, a person suffering, for example, from multiple sclerosis, should regularly engage in physical activity. Moreover, exercises should be performed according to the principle of a broad pool.
The idea here is that brain neural networks are not narrow but broad. Demyelination usually does not affect the entire brain at once, but rather individual regions of it. Accordingly, it is possible to identify specific functions, movement amplitudes, or postures that have been lost, and these are exactly what must be trained.
The most reasonable strategy is the use of a wide range of exercises.
The diversity of physical stimuli allows the mechanisms of cell migration to be activated and helps support recovery processes, thereby reducing the risk of secondary neurodegeneration. In essence, this allows the brain’s neural network to respond more flexibly to damage 🧠.
With this approach, it is important to understand where exactly the demyelinating damage is localized.
Sometimes this is relatively easy to observe 👁. For example, a patient’s vision may worsen not completely, but by about 20%. The cause might be a partial impairment of the eye muscles — for instance, the left eye may begin to drift and lift upward less effectively. In such a case it becomes clear that the problem is related to eye muscle coordination, and those muscles must be trained.
However, there are also more complex cases of targeting.
For example, with lesions associated with the pelvic floor muscles, a patient may lose balance ⚖️. At the same time, the muscles themselves may retain strength, but their coordination interaction becomes impaired. In such cases, balance must be restored through postural exercises — for example elements of yoga, sumo stances, or kettlebell exercises.
In other words, the problem lies not in muscle strength itself, but in the interaction between muscle groups.
Another important area of targeting involves speech functions 🗣. For example, it may be noticed that a patient begins to pronounce the sound “r” worse or develops a scanning type of speech. This also indicates specific disturbances in neuromotor coordination.
This is why every individual case requires precise and individualized work. A broad pool of exercises makes it possible to select a set of stimuli corresponding to a specific lost function. This is both the difficulty and the strength of such an approach.
In addition to physical stimuli, chemical stimuli are also frequently described in the scientific literature 🧪.
It is not only about physical exercise. The human central nervous system is regulated by a large number of neurotransmitters. These neuromediator systems can produce chemical excitation of certain areas of the brain and thereby initiate the migration processes of oligodendrocyte precursor cells or even the growth of certain areas of nervous tissue according to the principles of neural network Darwinism.
From this arise various ideas of targeted therapy — for example hormonal therapy or pulse therapy.
Under certain conditions, it is indeed possible to stimulate the growth or restructuring of the nervous system through chemical interventions. However, a serious problem arises here ⚠️: many such substances belong to potent or potentially addictive compounds.
Thus, a duality appears. On the one hand, chemical stimulation may potentially induce remyelination and even the growth of nervous tissue in certain regions. On the other hand, it is associated with significant risks.
Therefore, such methods require extremely precise and cautious application. However, when used correctly, they can indeed open new perspectives in neurotherapy.
