這篇文章非常有趣︰ What Makes Us Moral
根據科學家的研究﹐我們的道德行動和我們的腦部運作有關哩!

Where Decisions Are Made碰到道德上的兩難問題時﹐大腦的哪些部位為我們做決策?

Understanding the intricacies of our most complicated organ is a scientific work in progress, but there is some consensus on how the brain tackles moral dilemmas. There are some of the major regions involved in moral decision-making.


前扣帶皮質 Anterior Cingulate Cortex

Difficult moral dilemmas increase activity here, signaling the Dorsolateral Prefrontal Cortex to provide executive control

中前額葉皮質 Medial Prefrontal Cortex

This part of the brain, associated with emotion and social thinking, was one of the regions damaged in the famous case of Phineas Gage, whose personality changed from kindly to belligerent

杏仁核 Amygdala

This almond-shaped mass of gray matter is associated with strong emotions like fear

後側前額葉皮質 Dorsolateral Prefrontal Cortex

Associated with cold cognition (like remembering a phone number), it becomes more active when people make utilitarian choices.
