The society and the information 24:  Wonder of brain and nerves 2

 brain

< 1. brain 


We look at an information system of sense and movement in brain.

感覚と運動の情報システムを見ます。


 the function of brain

< 2.  the function of brain >

The splendid control system

For example, I assume you lift a boiling kettle.
You touch the handle with confirming it by eyes, and lift it along with grasping so that it may not incline.
At this time, the motion of the hand and the arm were continuously controlled with the feedback control of hot water quantity in the kettle, or an incline of it.
When you touched the heated handle of the kettle, at once you will let go of your hold on it.
If you are carrying it, you will carry it to the neighborhood with being prepared for your burn. 
At this time, the former was a reflex reaction before going into your brain.
As for the latter, the advanced processing was done in brain, because you will suffer a big burn in your feet, when you let go of your hold on it.
Probably, when being holding the kettle, even if someone speaks to you, you will be able to complete also the work while talking.


素晴らしい制御システム
例えば、あなたが沸騰したヤカンを持ち上げるとしましょう。
あなたは目で確認しながら取っ手に触れ、握りながら傾け無いように持ち上げます。
この時、やかんの湯量や傾きの感覚情報を連続的に帰還制御し手と腕を動かしていた。
もしあなたが熱いヤカンの取っ手に触れた時、とっさに手を放し、もし運搬途中なら、火傷覚悟で近くまで運ぶでしょう。
この時、前者は脳に入る前の反射的な反応をした。
後者は、もしそこで手を放せば、足などに大きな火傷を負うことになると脳内で高次の処理がなされた。
もしヤカンを持っている時、誰かがあなたに話しかけても、会話をしながら作業が出来たでしょう。


a flow of the information processing 

< 3. a flow of the information processing >

* The input information is processed at multiple levels in a number of cerebral fields.
On the other hand, as for an emergency and everyday repetition movement, it is performed reflectively before going to the brain.

* Much control is carried out without being conscious, and if needed, you can do it consciously. 

     入力情報は脳の複数の分野で重層的に処理される。一方、緊急時と日常的な繰り返し運動は脳に入る前に反射的に行われる。
     多くの制御は意識せずに行われ、必要に応じて意識して行うことも可能です。


our brain leaving a trace of the evolution 

< 4.  our brain leaving a trace of the evolution >

Structure of our brain from the point of view of the evolution

The reason why the brain is controlled at multiple levels is related to the evolution of a living thing.
As shown in above picture, human beings' brain becomes large so that some functions are added, and its whole came to unite.
The fishes that have an old brain as the evolution react almost reflexively to sensory information.
In the reptiles, the sensory information came to unite a little, and then in old sort mammals, emotional control (anger, sympathy) was added on it.
In new sort mammals that a cerebral cortex developed, a large number of advanced processing fields combined together, and in human beings, thought and consciousness were added on it.

進化から見た脳の構造
脳の制御が重層的に行われている理由は生物の進化と関係しています。
図のように、人類の脳は機能が追加されるような形で大きくなり、それ全体が連合するようになりました。
進化的に古い脳を持つ魚類は、感覚情報にほとんど反射的に反応します
爬虫類では感覚情報の統合が少し進み、古い哺乳類では感情的な制御(怒り、共感)が加わります。
大脳皮質が発達した新哺乳類では、多数の高次の処理野が連合し、人間では思考や意識が加わります。

Point

This multistory feedback control was indispensable to the brain that enables quick accurate action.
However, there are two problems also in the system born by this evolution.

*The nerves to inform the early abnormalities (cancer, mental disease) in the brain or the internal organs are insufficient.

* As for being controlled automatically in the brain, conversely, for us, it is difficult to notice the mistake or the defect, and to correct it consciously.

This is similar about the information system of our society and organization.
By ourselves, we must cope with the expansion of community scale (globalization), and the progress of information media (the Internet).

Next time, we look at a wonder and a danger of the information processing of the brain.


ポイント
素早く適確な行動を可能にする脳に、この重層的な帰還制御は不可欠でした。

しかしこの進化で生まれたシステムにも問題はあります。
     進化途上において重要では無かったのか、内蔵や脳自身の初期異常(癌化、精神病)を知らせる神経が不足しています。
     脳や神経が自動処理していることは、逆に言えば、その間違いや欠陥に気づかず、また意識して修正することが困難だと言うことです。

このことは我々の社会や組織の情報システムについても同様です。
我々自身で社会規模の拡大(グローバル化など)、情報媒体(インターネットなど)の進歩に対応しなければならない。

次回は、脳の情報処理の不思議と危うさを見ます。

History of sickness and medical art 22:  India 2

God of India

< 1. God of India >

We look at the medical art of ancient India from this time.

Atharvaveda
This was established in about 1000 years B.C., was a sacred book for the private sectors, and had a relationship with medical treatment most.
This excluded disaster by magic, prayed for beatification, and aimed for medical treatment, love, victory, good luck, and expiation.
The object of disease treatment was diarrhea, heart disease, skin disease, tumor, fracture, intestinal worm, and poison of snake, and eye disease etc.
And it also included energy reinforcement and long life.
For example, the treatments were that a patient caught the hand of a magician, and made an incantation.
The treatment of fever was to transmit it to a woman of Sudra (slave), and the treatment of headache and coughs was to transmit it to the trees of hill and forest
For constipation, the patient was made to drink the soil of a rat hole along with singing a devotional song.


今回から古代インドの治療を見ていきます。

これは前1千年頃に成立し、最も治療に関わりを持つ民間向けの聖典でした。
これは呪術により災厄を祓い、招福を祈願し、治療、恋愛、戦勝、開運、贖罪などを目的とした。
病気治療の対象は下痢、心臓病、皮膚病、腫瘍、骨折、回虫、蛇の毒、眼病などがあり、精力増強、長生きも含まれていた。
例えば、治療は患者が呪術師の手を掴み呪文を唱え、熱病はシュードラ(slave)の女に、頭痛と咳は丘と森の木々に感染させることであった。
便秘に対しては、賛歌の詠唱と共に、患者は鼠穴の土などを呑まされた。


The spice of curry was based on Ayurveda

< 2. The spice of curry was based on Ayurveda >

Birth of Ayurveda

In the early stages, Brahmin (flamen) doubled also as doctor, and mainly treated sickness by means of using magic.
Before long, the experience and the knowledge about sickness or medicinal herb had been accumulated, and two medical schools that specialized in the internal medicine and the surgery treatment appeared in the 6th century.
These had been integrated into a system of Ayurveda (knowledge of the life) during several centuries A.D., and moreover it adopted yoga and developed.

初期は、バラモン(祭官)が医者を兼ねて、主に呪法を用いて治療を行っていた。
やがて病気や薬草に関する経験と知識が蓄積され、前6世紀には、内科治療を専門とする学派と外科治療も取り入れた学派が出現していた。
これらが紀元後数世紀の間にアーユル・ベーダ(生命の学問)の体系に集成され、さらにヨーガを取り入れ発展していった。


16 major nations: The first city-states were born.

< 3. 16 major nations: The first city-states were born. 
When it came at the 7th century B.C., rice cropping and trade became popular in Ganges basin, and many city-states were born.
This pushed the society toward the birth of freethinker, Sakyamuni, and medical school.

7世紀になると、ガンジス川流域で稲作と交易が盛んになり幾多の都市国家が誕生した。
このことが自由思想家、釈迦、医学学派の誕生へと向かわせた。

Change of the medical treatment

According to typical etiology of Ayurveda, the sickness was that the equilibrium among yellow bile, viscous liquid, winds, and blood collapsed.
In order to regain this equilibrium, patients must eat and drink sweet, acid, bitter, salt, and astringent depending on his condition.
For example, it is said that the acid is effective in the increase of digestion or mental function.
There are many medicines to treat, and they consist of minerals, animals, and 1000 or more kinds of medical herbs, and the purpose and the usage are classified.
Some medicines were the Egypt origin and the curative medicines of skin disease reached 100 kinds.
There were many medicines with clear effect and they used opium, ginger, cinnamon, wolfsbane, castor oil, alum, mercury, etc.
The mainstream of medical treatment was emetic method, enemas, nasal drops method, and phlebotomy method (bloods are drained).



アーユル・ベーダの代表的な病因論では、胆汁、粘液、風、(血液)の平衡が崩れた状態が病気と考えられている。
この平衡を取り戻すには甘・酸・苦・辛・塩・渋の六味を症状に応じて飲食させる。
例えば酸は消化力増大・精神機能増進に効果があるとされている。
扱う薬物は多く、鉱物、動物、一千種類以上の薬草があり、目的と用法が分類されている。
薬物にはエジプト由来もあり、皮膚病の治療薬は百種類に達した。
効能が明確な薬物は多く、アヘン、ショウガ、シナモン、トリカブト、ヒマシ油、明礬、水銀などを用いた。
治療法は吐法、浣腸法、点鼻法、瀉血法(血液を一部抜く)が中心である。

< 4.  a relief engraving of a tooth extraction  >

The name of diseases of internal medicine exceeds 300 kinds, and hiccups, the illness of head, and insanity are also included.
There were surgical operations of anal fistula, fracture, tooth extraction, renal calculus, cataract, and nose job, etc. 
The doctor did auscultation of patient, observed the state of his skin or his tongue, and judged diabetes with tasting his urine.

In this way, the conversion to medical art of empirical science from it of only past magic happened.

内科の病名は300種類を越え、シャックリ、頭の病、狂気も含まれている。
外科手術には痔瘻、骨折、抜歯、結石、白内障、鼻の整形などであった。
医者は聴診、皮膚や舌の状態を観察し、患者の尿を味見し糖尿病を判断した。

こうして過去の呪術一辺倒から経験科学の医術への転換が起こった。

It was fine on that day, and the sea and the sky were wonderful colors.
This port town was large and was overflowing with tourists and citizens.
Many sardines are rested in fish shops, and we ate fried sardines at lunch.

この日は快晴で、海も空も素晴らしい色だった。
この港町は大きく、観光客と市民で溢れていた。
魚屋には沢山の鰯が並んでおり、昼食に鰯のフライも食べた。

Sea of Marmara

マルマラ海

< 4. a view of Asia side from a ferry >

There are the Dardanelles in right distant place, and the Bosporus in left distant place.
In the second millennium B.C., many ships of Greece loading up with the cereals of the Black Sea coast came and went this sea.
It had produced the prosperity of Troy of an ancient harbor city, and it created a myth of Trojan War "Iliad".
Then, the great army of Persia crossed the both straits many times, and attacked Greece.
Subsequently, Alexander the Great crossed these straits and destroyed the Persia.
Precisely, these histories seem to be happening in front of me.


右遠方にダーダネルス海峡、左遠方にボスポラス海峡がある。
紀元前2千年紀には、この海をギリシャの船が黒海沿岸の穀物を満載して往来した。
そのことが古代港湾都市のトロイの繁栄を生み、やがてトロイ戦争「イーリアス」などの神話を育んだ。
その後、ペルシャの大軍が幾度も両海峡を渡海し、ギリシャを攻めた。
次いで、アレキサンダー大王がこの海峡を渡り、このペルシャを滅ぼすことになった。
まさに悠々の歴史が目の前に迫ってくる。


 Ayvalik
After visiting the ruins of Troy, we go to Ayvalik of a stay place.
I introduced the ruins of Troy in “Travel to feel ancient times sir.2 / Troy in Turkey” of this blog.
The Ayvalik is a new town, new residences was covering the gentle hill and island being surrounded by seas.
Our hotel was in an island and I enjoyed a stroll of the island.


アイワルク
トロイ遺跡を訪問した後、宿泊地のアイワルクに向かう。
トロイ遺跡はこのブログの「最古を巡る旅 連載2/トルコのトロイ」で紹介しています。
アイワルクは新興の町で、海に囲まれたなだらかな丘陵と島に新しい住宅が広がっていた。
宿泊したホテルは島の中に有り、島の散策を楽しんだ。

The society and the information 23: Wonder of brain and nerve

 brain and nerve net 

< 1. brain and nerve net >

We take the human body for an example for understanding the information system.

We have taken the United States for an example in order that we may look at the circumstances of the information.
Apprising to a brain about the canceration of internal organs is like that whistle-blowing appeals against the corruption of an organization.
In order to prevent runaway war, it was required that people are exactly informed about the information of the government and the battlefield
It is like that a person is perceived a brain's own abnormalities and the situation of the external world by the visual and auditory senses.

We look at the important points from "brain and nerve", in order to understand " society and information",

                                                                                             
人体を例に、情報システムを確認します。

これまで米国を例に、情報の有り様を見てきました。
組織の腐敗を訴える内部告発は、臓器の癌化を脳に知らせるようなものです。
戦争を暴走させない為には、政府と戦場の情報が的確に国民に伝わることが必要でした。
これは脳自身の異常と外界の状況を視聴覚で察知するようなものです。

「社会と情報」を知る上で重要なポイントを「脳と神経」から見ます。


somatosensation: pain is due to “free nerve ending” only 

< 2. somatosensation: pain is due to “free nerve ending” only >

Wonderfulness of somatosensation
The nerve net and the brain have a skillful control function.

There are a huge number of sensory nerves that feel painfulness, heat, and pressure in our skin.
These nerves have two kinds of signal transmission system.
The pain continues sending the information to a brain, as long as there is a hurt.
On the other hand, if the contact pressure is changeless when a person has been wearing a dress, the information isn't sent.


体性感覚の素晴らしさ
神経網と脳は、巧みな制御機能を持っている。

私達の皮膚には、痛さ、熱さ、圧力を感じる膨大な数の感覚神経があります。
この神経の感じ方には2種類ある。
痛みは傷がある限り脳に情報を送り続けます。
一方、服を着ている時などの接触圧は変化がなければ情報は送られません。


 Lumbago 

< 3. Lumbago >
Occasionally, if we do not feel pains such as an injury and lumbago, we may think that it is good.
However, a person that inherently hasn't the pain sense will finish a short life after having wounds all over his body.
He burns with drinking boiling water without knowing it, or becomes lumbago with lifting a heavy thing, and becomes a serious illness irrecoverably.

If even the small part of the brain gets injured, is the pain sense of the whole body paralyzed?
In fact, unlike other sense organs, recognition of the pain is performed in a wide range  with a  brain, and a paralysis of the pain sense is prevented at least from occurring  by damage to a small part of the brain.
Similarly the long sensory nerves that have pierced through a backbone have also separated into two bunches, and it diversifies away risk.

我々は、時折、けがや腰痛などの痛みを感じなければ良いと思うことがあります。
しかし先天的に痛覚が麻痺している人は、満身創痍の末に短命に終わりやすい。
その人は、知らずに熱湯を飲んで火傷、重たい物を持ち上げて腰を痛め、やがて取り返しのつかない重症になる。

もし脳の一部でも損傷を受ければ、体全体の痛覚が麻痺してしまうのだろうか。
実は他の感覚器と異なり、痛覚の認識は脳の広い範囲で行っており、一部の脳の損傷ぐらいでは痛覚の麻痺が起きないように出来ている。
同様に、脊椎を貫いている長尺の感覚神経も二つの束に別れており、危険を分散している。


a shrine ritual of fire-walking

< 4. a shrine ritual of fire-walking >

Furthermore, a surprising function

If you encounter an earthquake, suffer from heavy injury with collapsed pillar, and then it is assumed that a fire is imminent.
An acute pain runs, you can hardly run away, and you may normally lose life.
However, the pain vanishes suddenly and you can get away and may be saved.
It is because a neural transmitter substance that is secreted from a brain has prevented the signal of the pain in a connection of the sensory nerve in the backbone.
It is the same as that you virtually hit the anesthesia of the painkiller by yourself in pinpoint.
The same things will have broken out in the brain of an ascetic of fire-walking.


さらに驚くべき機能が
もしあなたが地震に遭い、倒壊した柱で腰に深傷を負い、さらに火災が迫っているとします。
普通なら激痛が走り、とても逃げ出せず、あなたは命を失うかもしれません。
しかし突如として痛みが消え、脱出し助かるかもしれない。
それは、脊椎にある感覚神経からの連結部に、脳から神経伝達物質が分泌され痛みの信号を受けないようにしたからです。
まるで自分で、痛み止めの麻酔をピンポイントで打つようなものです。
火渡りの行者の脳にも同様なことが起きています。


a control system of a pain: A red line is pain signal and a blue line is control signal

< 5. a control system of a pain: A red line is pain signal and a blue line is control signal >

Point
The information such as pains is collected thoroughly, and is chosen depending to the importance of it.
The nerve net is made so that the damage to receive in accidents decreases.
In a process of the evolution, we got the wonderful system that detects the abnormalities of a body surface.

I look at the information system of the human body next time also.


ポイント
痛みなどの情報は徹底して収集され、重要度に応じて取捨選択されている。
その神経網は、事故などで受ける損傷が少なくなるように図られている。
進化の過程で、私達は体表面の異常を検知する素晴らしいシステムを得ました。

次回も、人体の情報システムを見ます。
