“All the experiences in your life- from single conversations to your broader culture- shape the microscopic details of your brain. Neurally speaking, who you are depends on where you’ve been. Your brain is a relentless shape-shifter, constantly rewriting its own circuitry- and because your experiences are unique, so are the vast detailed patterns in your neural networks. Because they continue to change your whole life, your identity is a moving target; it never reaches an endpoint.”
