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.
