How Brain Works. Minicolumn Hypothesis. Consciousness. Neurotransmitters and Drugs. Human Evolution. Transhumanism and Other Materials.

Как работи мозъкът. Хипотезата за миниколоните в неокортекса като градивен елемент на разума. Съзнание. Еволюция на човека. Трансхуманизъм. Класическо кондициониране и други интересни материали.

Some cited from Boris Kazachenko's knols, pointed by himself or commenters, some suggested by me, browsing around.

  • Classical Conditioning experiment with a baby, taught to be afraid of rats, eventually any furry objects. Displays also stimulus generalization. Immoral, but interesting:

  • Human Evolution:

    http://www.evolution-of-man.info/

  • Obstetrical Dilemma:

    http://en.wikipedia.org/wiki/Obstetrical_Dilemma

    --> bigger the brain/head of proto-human baby
    --> harder birth and dependent on help from others (obstetrician)
    --> shorter the pregnancy in order the baby to get ouf of the mother's pelvis
    --> more immature newborn baby
    --> more underdeveloped brain of the baby (20-25% fully developed, vs 45-50% in chimps)
    --> baby is more dependent on mother's care for a longer time
    --> mother is dependent on others' carе
    --> family, division of labour, society

    "Акушерската дилема" в еволюцията на човека

    --> по-голям мозък/глава на бебетата на еволюционните предци на човека
    --> по-тежки раждания и зависимост от чужда помощ (акушерки)
    --> по-кратка бременност, за да може бебето да се промуши през тазобедрената става на майка си
    --> по-недоразвито новородено
    --> по-недоразвит мозък (20-25% напълно развит при човека, докато 45-50% при шимпанзетата)
    --> бебето е по-зависимо от грижите на майка си за по-дълъг период
    --> майката е по-зависима от грижите на другите
    --> семейство, разделение на труда, общество
