The video is about 7 minutes. It contains a very easy-to-understand explanation scene about cognitive science integration. After watching, I think it will be easier to understand if you read the article below.


A phenomenon in which a load exceeding the rating is applied to an electric circuit. In recent cognitive science, it is also used when a large amount of signal flows into the neural circuit of the brain.

If an overload occurs in the electrical wiring of housing equipment and an overcurrent occurs, the wiring will be short-circuited. A breaker is installed to prevent this. The electric circuit is protected by the breaker tripping.

In fact, humans also have a function (breaker) based on exactly the same principle. It's a back pain, a crick, a severe pain attack of hip joints and shoulders. In recent years, a completely different perspective has been raised on pain, which has traditionally been thought of as a physical problem, and the International Society for Pain Medicine (IASP) is revising its definition of pain in line with these new concepts.

When brain overload occurs, circuit breakers are tripped (temporarily halting activity due to severe pain attacks) to protect neural circuits. The discipline that studies these dimensions of brain information processing is called cognitive science, and the attempt to integrate this into medicine is the Cognitive Science Integrated Approach (COSIA).

COSIA clinical studies show that when brain breakers fail, the risk of depression and dementia increases. A living body that has been hit by overload will show various signs (symptoms), but it has been pointed out that if these are masked (no symptoms appear), the risk of sudden death increases along with the risk of mental illness. .

 As symbolized by the English word "karoshi" (death from overwork), it is said that only Japanese people die from overwork in developed countries. For this reason, Japan boasts the world's best results in fatigue research.

As an example, we were the first in the world to discover that fatigue felt during work or exercise is not physical fatigue, but brain fatigue caused by a decline in autonomic nervous system function (the lactic acid theory of muscle fatigue). turned out to be erroneous).

 It is not the muscles that get tired from hard work at home or at work, but the brain.

At our association, we propose the concept of cerebral homeostasis dysfunction (BD) for this decline in brain performance.

Brain Homeostasis Dysfunction (BD)?

The function of keeping the internal environment (body temperature, blood pressure, etc.) constant against changes in the external environment is called homeostasis. Among human organs, the brain is remarkably vulnerable to oxygen deficiency, so it has an autoregulatory ability to respond quickly to changes in local blood flow. It also has a unique filter mechanism (blood-brain barrier) in substance exchange.

We call this homeostasis unique to the brain, which is not found in other organs.

If the overload continues, the function of blenostasis becomes unstable (generally expressed as brain fatigue or brain overwork). This condition is called brain homeostasis dysfunction.

Clinically, the signs of overload are diverse and appear in various dimensions, including locomotory, circulatory, digestive, and mental functions.

Among the above list, it is relatively easy to imagine the relationship with the brain for phenomena such as mistouching while working on a computer, accidental bites (biting the inside of the mouth), blurred vision, and shaky eyes.Related link "Forgetfulness and careless mistakes are due to brain homeostasis dysfunction (BD)? Surprising workarounds taught by experts" Nikkei XTREND

However, on the other hand, many people may be surprised to see that, even in light of existing medical common sense, "Huh? Is that also caused by the brain?"

However, in fact, the problem of overload is hidden behind orthopedic problems (chronic pain, frailty, etc.), and the expression of brain elastic plasticity (activation of brain resilience) improves pain and muscle coordination. COSIA clinical studies have shown that

Furthermore, in my image, I thought I had lifted my leg properly, but I tripped over a step and fell... I mistakenly stepped on the accelerator and the brake. It is known that such a phenomenon is seen not only in the elderly but also in a wide range of age groups, and it is inferred that the danger of overload extends to all generations.

Another worrying problem with BD is "masking". There are people in the world who do not feel any kind of fatigue or ill health despite being overloaded.

It has been reported that these people continue to run at full power under the recognition that they are normal and in good health, increasing the risk of sudden death.

In this way, even though you are really tired, you do not feel any fatigue at all - BD masking - has the following risks as well as sudden death. Fractures due to falls, careless mistakes at work, driving errors, strokes and heart failure, delayed detection of cancer, depression and dementia, etc.

And there is also the troublesome problem of the separation between consciousness and the body. For example, when you are full from a meal, even though the signals from your stomach are reaching your brain, your consciousness will be under the illusion that you haven't had enough, and you will continue to eat. My body craves water in the scorching sun, but my consciousness doesn't feel thirsty...

You can understand how dangerous the situation is when the brain cannot accurately grasp the state of the body in this way when considering recovery and prevention from illness.

As I have introduced so far, there are a wide variety of poor physical conditions related to overload, but the number of modern people with such problems is steadily increasing.

The reason for this is that the rapid transition to a super-information society symbolized by IT and DX and the drastic changes in the global environment (severe seasonal changes and an increase in natural disasters) overlapped in time. It is considered

In recent years, terms such as weather sickness and weather pain have become common, as well as autonomic imbalance, which has been known for a long time, as well as developmental disorders, mental disorders, psychosomatic disorders, etc., and from orthopedic surgery to convalescent rehabilitation. Overload is lurking behind really various pathologies.

As an example, there are cases where the introduction of the gravity release approach (a technique to reduce gravity load) in locomotorium rehabilitation leads to dramatic recovery. Depending on the patient's situation, there is a latent risk of overload in the rehabilitation environment, and it is inferred that removing the training load and shifting to brain relaxation will make it easier to see the effect. (this is just an individual problem).

Overload is also closely associated with sensory processing disorders, such as numbness unrelated to neuralgia (paresthesias), hypoesthesia, taste disorders, olfactory disorders, auditory processing disorders (APD), and hyperesthesia (autism). including the tactile defense of the so-calledSensory processing disordersare known to be related to most of the

It is no exaggeration to say that overload is inevitable in people with HSPs (increased sensitivity), empaths (increased empathy), and developmental disorders (our association recommends the term developmental individuality). In clinical practice for these patients, an approach based on BD is necessary.

In the Cognitive Science Integrated Approach (COSIA), emphasis is placed not only on interventions for symptoms, but also on conveying new perspectives and information brought about by cognitive science (promoting cognitive updates).

To reiterate, in this era of simultaneous transition to a hyper-information society and drastic changes in the global environment, many modern people are at risk of overload. We believe that the perspective of integrating medical care is extremely important.

There are various methods in the Cognitive Science Integrated Approach (COSIA), but as a treatment system to determine individual characteristics,BFI (technology that connects the brain and fingers)or.(Cerebral elasto-plasticity-guided non-invasive selective integration method))etc.

For those interested in Cognitive Science Integrated Approach (COSIA)

The Cognitive Science Integrated Approach (COSIA) is a concept that represents the “integration of cognitive science and medicine” and has its origins in pain management in musculoskeletal primary care.

In the current situation where image labeling and diagnosis of the cause of pain diverge, the International Association for the Study of Pain (IASP) has revised the definition of pain and is shifting to the "emotional origin theory of pain."
