  • There is a serious criticism about this book, by Yuko Yotsumoto, assistant professor of Tokyo Univ.; commenting that there is little scientific proof of the difference of brains between men and women, as well as little reflection of the results of the latest neuroscience research; furthermore, the data cited in the book obsolete and almost 40 years old that women's brains have 20% more wider corpus callosum, which is now denied by the major researchers.
  • This book, though becoming a best seller, describes too much neurosexism, or is a kind of pseud0-science, the authority concluded.
Original resume

>Top 0. Introduction:

  • Human character mostly depends on the circuit or network of a device called brain.
    • AI, which is now growing rapidly, is trying to imitate the function of our brain.
    • It is not easy to understand the behavior of a human being as the feature of his or her brain.
  • It has been discussed there may be a substantial difference between men's brain and women's one.
    • Men's brain does not function as women expect, or vice versa.
    • Different devices need to be treated differently.
    • In addition, brains changes as the years pass; younger brain tends shows input oriented, matured brain output.
    • This book is about operating manuals for both healthy brains; nobody hasn't see such manuals, though our brain could or should be used for lifetime.

1. はじめに:

  • 人間の脳は、男女で役割の重点が異なる。
  • その違いを認識した上で、相互に相手の脳の操作マニュアルを考える。

>Top 1. Sex difference in brain:

  • 1982-92: ICOT, a big national project in Japan, promoted by then MITI spending ¥57B.
    • aimed to develop parallel computer based on different architecture.
    • thereafter, such parallel computer became unnecessary; sequential computer has been developed much faster, processing even big data.
    • in addition, the Internet itself became a kind of massively processing machine.
    • from now on, it is urged to make an order in a chaotic virtual space.
  • Nursing care robot, particularly dialogue robot need to be designed differently for aged men and women.
  • Top Information perceived by five senses is different between men and women.
    • Some women (around 7%) are known to have tetrachromatic (not trichromatic) cells, who can recognize different perception of 'purple' color in the red zone, or feel sensitive gradation from pinkish to purplish color.
    • Such women can easily recognized delicate change of face color of a baby, or degree of rotting of foods; they had shown quite effective ability in collecting tree nuts or fruits.
    • A woman designer of watch maker could distinguish very pale purplish or greenish anti-reflective coating of a watch; claiming to change it into more transparent it; but men designers were amazed such claim; men could not recognize it.
      • In designing pinkish or purplish color in textile, such difference of perception is usually happened between men and women.
      • It is needed that the final judge of marking regarding color sensitivity should be done by women.
    • Such difference is not confined to the sensitivity of colors; recognizable frequency of sound, sensitivity of olfactory.
      • Younger women (no more than 25 years old single) could show amazing sensitivity; they can splice optical fiber of 1/7 width of a hair.
      • Difference of cognitive range means difference of feeling of comfortableness.
  • Corporate society is basically established by men's brain; aiming to supply uniform quality of goods with minimum cost and earliest delivery to the market.
    • The function of men's brain is just fit for reasonable, efficient, and constant manner of operation; which is the basic structure of capitalism.
    • Even if the top management of this organization is women, who must operate with the type of men's brains.
  • On the other hand, women's brain function to care about every environment around themselves; which is essentially needed to raise children.
    • Women's brain of reproductive age tends to show paranoic behavior, to protect the weakest existence; which is located at antipodes against business-like behavior.
    • The ratio of women's brain is different from the ratio of gender; there are men who have women's brain, or vice versa.
    • In any organization, the diversity is important; women's brain is keen about the the feelings of customers, producers, and other related or non-related matters; these behaviors are important to perform wide-range of services.
    • Any type of brain has no defect; there should be some domain which needs any type of function.
      • Spacial perception is well exerted by men's brain.
      • Writing novels is probably good at women's brain.
      • catchphrases or naming of goods are often promoted by a creator who is rather poor in ordinary communication.; the defect of poor communicative ability could be an advantage.
      • Technicians are often referred as skillful though poor talkers; but it must be that they are skillful because of poor talkers.; so-called defect could be a source of advantage.
  • In company organization, women's brain often demonstrates strength in 1) prediction of troubles, 2) innovative ideas, or 3) appropriate measure for uncertain future.
    • Such abilities of women's brain had not been well utilized in men's brain governing organization.; even after the Equal Employment Opportunity Law, women's brain could not perform well.
  • Difference of men's brain and women's brain:
    • >Top Corpus callosum (CC) (>Fig.)
    • Woman's (as well as homosexual's) carpus callosum is 20% thicker than that of man.; the number of nerve fibers become more, because women's ones are thinner.; communication between the left and right is several or several ten times smoother.
      • this means that right and left brains work more corroboratively; feeling can be quickly changed into words (power of flexibility, or debrouillard).
      • women's brain can instantly symbolize or covert code what they feel.
      • men's brain cannot respond to the trivial changes, but simulates more maniac function using local specialities in the brain; almost neglecting own feeling but does more objective judgement.
      • feeding center and libido center are nearer in women's brain.
      • >Top men produces testosterone, male hormone every morning, which affects to his turf-consciousness; inducing dopamine which creates active curiosity.
      • women secretes estrogen and progesterone, both female hormones, in the menstrual cycle.
    • We see something, which is recognized by excitation of particular neurons.
      • In response to a threshold action of electrical potential, a neurotransmitter (chemical materials) is released; which move across the synapse to be detected by the receptors.
    • In ovulatory phase (secretes estrogen), women's brain signs to take aggressive action in her behavior.
      • >Top homosexual brain has the function of women's type brain (more sensitive) and men's type (more curiosity), which looks like the strongest brain as a human being.; a corporate board including gay directors is said to cause corporate prosperity (diversity inclusion).
      • men's brain is made posteriori by receiving male hormone, testosterone, shower from 6-24 weeks after pregnancy; making thinner corpus callosum.
      • some men have not thinner corpus callosum, showing hybrid brain features; and a part of men having thicker corpus callosum tend to show homosexual.
      • women's brain has basically thicker corpus callosum; if which does not function well in collaborating right and lest brain, such women's brain resemble to men's one. (GID, Gender Identity Disorder; or transgender; or LGBT).
      • there are individual differences in each gender brain.
    • Men's brain requires evaluation of his performance; and women's brain needs words of appreciation.
      • there is a limit of brain capacity; which couldn't contain two type of brain functions, then each different function of brain was made.
      • the problem is one type of brain cannot recognized the difference of the other; men and women are obliged to live together feeling everyday stupidity of the other type of brain.
      • Such difference is important, both functions are need to survive in any environment.
    • >Top Weakness or difficulty or clumsiness could be advantages:
      • the brain of professionals must be attained by posteriori training.
      • innate ability tends to encounter earlier limit of development.

>Top 2. Amazing women's brain:

  • Features of women's brain:
    • As it has thicker corpus callosum, collaboration of right and left brain is better.
      • Right brain mostly relates to subconscious mind (space recognition and imaging invisible thing), while left brain conscious mind (word or signal manipulation).
      • women's brain shows practical, quick, and considerate response, combining image processing in the right brain and signal coding in the left using thicker corpus callosum.
      • particularly, mother in raising younger children shows amazing performance in such confused and bazarre-like spaces.; they shows enormous capability in shopping or domestic works or handling activities in small community (like PTA, festival, etc.)
  • >Top Manual-1 (Operation Manual to understand women's brain): Hear the story anyway.

        • women's brain expect sensible or tasteful services from men's brain.
        • Lady first custom is smartly prepared for satisfying this requirement.
  • Manual-3: Never say that you should have told me earlier.
    • Never say "You should have told me it earlier."; this utterance is understood to give up conjecture or kindness to women's brain.
    • Never say "What are you angry at?" "What are you getting at?"

      • women' brain grows larger in knowledge or remedies capacity as time goes by.
        • increase of the experiences deepens confidence.
        • consequently women' age corresponds to frequency of unwavering answers, such as finding out essential and reliable answer in confused or messy situation.
        • women's brain tends to underestimate advice of younger women's brain.
    • Output ability of brains maximizes since around middle of fifties; while input ability deteriorates since then.
  • Manual-5: Flash-back all memories with emotional tag.
    • When women's brain brings up men's past insensitive comments or behaviors, which had been solved or settled longtime ago, it is best to simply apologize it without felling irritated.

  • There four brains model of Ned Hermman, 1996; I wonder either 1) the men's brain correspond to Left brain of the limbic system, and the women's brain to Right brain of it; or 2) the men's and women's brain can be explained to have different function, as the women's brain functions as an unified efficient corpus callosum, and the men's one functions independently and dispersively in the extended (virtual) world.
  • In the former case, we need to manipulate four brains, while in the latter case, six brains.
  • Anyway we must manage to operate our internal parliament composed of 4 or 6 different independent small parties, or as a married couple, 8 or 12 ones in home management. Smart ability of political savvy is urged.
  • Ned Hermannによる4つの大脳モデルがあるが、以下いずかになるのか疑問がある。1) 男性脳が辺縁系左脳に、また女性脳が辺縁系右脳に対応するのか、それとも、2) 男性脳と女性脳は全く別の機能を持ち、女性脳は効率的な脳梁を通じて統一脳として機能し、男性脳は、それぞれ独立的・分散的に拡張されたバーチャル世界での機能を重視するということなのか?
  • 前者の場合は、我々は4つの脳を、後者の場合は6つ脳を操る必要があることになる。
  • ともかく4〜6の独立小政党からなる内部議会を運営しなければならず、結婚していれば、家庭運営のためには8〜12の小政党ということになる。賢明な政治手腕が求められる。
