(根據文章,是什麼解釋了夢境不合邏輯且荒誕的本質?)

  • (A) The complete inactivity of the amygdala during deep sleep

    • 錯誤:第 2 段指出杏仁核(amygdala)在 REM 睡眠期間活動顯著,甚至是達到或超過清醒時的水準,而非完全停止活動。

    • 錯誤:大腦並非全無新陳代謝活動,某些區域(如杏仁核)活動反而非常旺盛。
  • (C) The hyper-activation of the prefrontal cortex during REM sleep

    • 錯誤:前額葉皮層(prefrontal cortex)活動是大幅「減少(drastically reduced)」,而非過度激活(hyper-activation)。
  • (D) Decreased activity in the brain region responsible for logical reasoning and executive function.(原題幹與選項文字微修以求精準:Decreased activity in the prefrontal cortex/logical reasoning region)
