Deep dives
The Central Role of the Brain
The brain is fundamentally the most critical organ in determining who we are, serving as the densest representation of our identity. Unlike other organs, which can recover from damage or be replaced—like artificial hearts—the loss or alteration of even a small amount of brain tissue can profoundly change a person's characteristics, aspirations, and abilities. This emphasizes the brain's unique role in our consciousness and personal experiences; it is the 'city center' of our body's communication network. Therefore, any damage to it carries more significant consequences than damage done to other organs, making it crucial to understand and protect.
