>Top 1. Character & Habit of Brain:

  • ¶ Is it useful to make efforts?:
    • Cause: there is an 'effort gene'.
    • Trend: there are two kinds of persons; one who owns effort gene, and the other doesn't.
      • The former has genetically has an ability to continue to take efforts, or even feels pleasant to make efforts; consequently the former one can be successful in any kind of examination.
    • Impact:
      • The present entrance examination (for universities, etc.) mainly measures the ability of memory.
    • Advice:
      • The one who has not such effort gene should show their abilities in other areas, finding their suitable aptitude.
  • ¶ Why Japanese soccer players can not perform active play?:
    • Cause:
      • It is decided by a particular gene; serotonin is called as a hormone of happiness, which is secreted relatively more in optimistic type of players; while Japanese players usually secrete less.
      • >Top Where, 'serotonin transporter' removes serotonin from the synaptic cleft back into the synaptic boutons.
      • Average amount of secretion of serotonin: 50% in US &Europe, 30% in Latin America, while 70% in East Asia, and 80% in Japan.
    • Trend:
      • For most of Japanese players, it is a satisfaction not to fail in playing. They often will not challenge risks in defending and in offending in a game.
      • For most of European, or particularly Latin American players, it is a satisfaction to make a success.
    • Impact:
      • There should be an appropriate method of training depend on the features of brains of the players of a particular country.
        • The Japanese have the most worrying temperament in the world.
      • As an advantage, the Japanese will eager to practice very much preparing the forthcoming games, to eliminate uneasiness.
        • Also the Japanese save money in preparing for the future risk.
  • >Top ¶ We have two decision-making methods:
    • X-system: refleX-system, decision-making reflectively; this is more quick decision, but not so exact.
    • C-system: Calculate-system, decision-making by calculation; this is more exact but takes more time.
      • The Japanese tends to select C-system decision-making to adopt more exact and safer decision-making.
      • Japanese train operation is quite exact in operation; the Yamanote Line, round trip in about one hour in Tokyo, can accumulate in running roundly in 10 days within only 15 seconds out of the schedule.
      • There should be no alternative in decision-making for a forward player in soccer game; if there are plural alternatives it takes more time.
    • Cause: >Top 'Dopamine receptor':
      • Switch sensitivity to the dopamine receptor varies among people:
        • one who is sensitive can respond easily dopamine receptor with small amount.
        • the other one who is not sensitive need more stimuli by dopamine receptor; tends to take more challenges to be more satisfactory.
          • SA, 40% vs. Asia 5-6% vs. Japan 1%
          • SA players challenge too much, Japanese players too less.
          • In a case of failure of shooting goal, Japanese spectators will boo regretfully too much, while SA ones will boo not to take challenge.
          • In Japan, challenging will not be appreciated.
    • Advice:
      • to make a routine of 'failure' in daily practices; making failures should be within the scope of assumption.
  • >Top ¶ Which is effective 1) Carrot and stick policy, 2) Carrot only policy, or 3) Stick only policy; in making choose the correct route for a mouse; herein Carrot is bait, and Stick is an electric shook.:
    • A: Carrot only policy is most effective. A mouse may stop at the crossing to avoid the stick. The best way is 'Carrot or Neglect policy' (Ame or mushi)
  • >Top ¶ To reinforce Navigation neuron; relates 'unconscious action'.
    • Ability will be enhanced by repeating practices of the same things.
    • Even challenging should be routinized.
  • ¶ How to do well in the actual game?
    • It is rather better to visualize uncertainty or anxiety:
      • Write out and accept the anxiety or the cases of failure.
      • Rather than compressing or concealing the anxiety.
      • Astronauts receive trainings which look like real emergent cases; then they can respond to the emergency just like the case of trainings.
  • ¶ Efforts are needless to succeed?
    • Here it is actually 'wasted efforts.'
    • One who had endeavored to realize some unattainable goal, the one could gain nothing but regret or resentment, if failed.
      • You should think that the process of endeavoring is really meaningful, or what do you want to attain, analyzing calmly and objectively your potentiality.
      • Consider case of an Olympic athlete who aimed to get the gold medal resulted in the bronze medal; the athlete has spent meaningful times for hard training for the beloved sport, accepting the process is more valuable than the result of the match.
      • It is important to set up the really probable or realistic goal for the athlete or any other challenger from more reasonable and rational decision.
    • Continuing to exert oneself for less possible goal may cause to be exploited by some malicious magical group, a religious cult, sweatshops or fraud group; they surely require more donation to attain the unrealistic and unattainable goal.
  • ¶ The advice of 'efforts will be rewarded' is half-true; it is a beautiful lie.
    • It should be restated that 'make efforts which could be rewarded.'
    • Human ability is determined by own gene to a certain extent, which could be difficult to change it.
    • It is rational to ascertain the possibility or the limit of one's own ability; to find the goal within one's reach, which should be the real ability.
      • There are actions which one can do or cannot.
      • Human beings have assigned the latter to some others who can do it, for which we have developed communication ability.
  • >Top ¶ The Japanese tend to addict oneself to exerting anything, due to lack of serotonin.
    • Serotonin is thought to be a contributor to feelings of happiness.
    • Serotonin is synthesized via tryptophan, an essential amino acid; meat and banana are good food to increase such amino acid.
    • In order to live long, it is a good strategy not to fight.
      • Samurai loads who avoided to fight in feudal age generally live long, like Tokugawa Ieyasu (75) , Shimazu Yoshihisa (79), and Takeda Nobutora (81), Ukita Hideie (84).
      • The object of most of the animals is to live long and to have more descendants; human beings look exceptions, trying to make a name for oneself.

    • The person whose level of oxidase of monoamine is lower feels more state of happiness.
      • But the person who feel unhappiness may live long.
  • ¶ The effect of communal life:
    • Epigenetics: a change in phenotype without a change in genotype. Epigenetic change is a regular and natural occurrence but can be influence by age, environment, lifestyle.

      • ACC is presumably related to the feeling of anger.
  • ¶ Respond to an aggressive person:
    • >Top An aggressive character causes to feel pleasant when attaching.
      • Appology or response is not effective in this case.

  • ¶ L-type and S-type of Dopamine receptor:
    • This related to Evolutionary Development Psychology (EDP), focussing on the epigenetic processes to explain how evolved psychological mechanism appears as the phenotypes.
    • >Top The most prevalent DRD4 (Dopamine Receptor D4) VNTR (Variable Number Tandem Repeat) alleles are 4-, 7-, and 2-repeat alleles, with global mean frequencies of 64.3%, 20.6%, and 8.2% respectively.
        DRD4 4R (S-type) is associated with more risks averse behaviors while DRD4 7R (L-type) is associated with more novelty-seeing and risk-prone behaviors.
      • A possible explanation that individuals with 7R allele are generally more susceptible to environmental influence; display enhanced sensitivity to both negative and positive environments to both risk-promoting and enhancing environmental conditions.

      • In good fatigue, by creative activities, nerve cells swells, then which make new neuron connection after sleeping.
        • Seeking novelty is a good fatigue for brain.
        • Sleeping is the best remedy.
      • In bad fatigue (such as exceeded stress, cortisol is more secreted.

Comment
  • Neuroscience looks like a crossing frontier of natural science and social science; a frontier approached from physiology and from psychology.
  • Rapidly growing field looks similar; combination of different approach of scientific fields, such as astrobiology (astronomy and biology).
  • Life might appear and develop at brackish zone; mixture environment of salty and fresh water.
  • 脳科学は、自然科学と社会科学の交わる領域のフロンティアにある。生理学と心理学のフロンティアである。
  • 急速に発展している分野は同じように見える。異なる科学の領域からのアプローチの組合せである。天文学と生物学の交叉する宇宙生物学もその一つである。
  • 生命も汽水領域で発生成長したのかも知れない。そこは塩水と淡水の交わる領域なのである。
