AI Overview
laterality/ˌlatəˈralɪti/
Laterality refers to the preference of one side of the body for certain functions (e.g., right-handedness), which stems from the specialized functions of the brain's two hemispheres (cerebral lateralization). For instance, language processing often occurs in the left hemisphere in right-handed individuals. This phenomenon is fundamental to human and animal behavior and is also observable in plants.
你有沒有想過，為什麼只有少數是左撇子？這種「左右差異」其實不只出現在人類身上。在科學上，我們稱這種大腦或身體功能在左右兩側不對稱的現象為偏側性（laterality）。
過去人們以為，偏側性是人類獨有，但後來越來越多證據顯示：從鳥類到哺乳類，都有偏側性！
