In "Exhalation," what is the narrator's initial belief about memory?

Narrator believes that memory is recorded in one's brain.

Explanation:

In "Exhalation" by Ted Chiang, the initial assumption of the narrator is that memory of a person stores a huge list of things a person is going through.

When we exhale, it has been researched that, the part of the brain that stores memories is less stimulated as compared to when we inhale.

Thus, narrator also believed that whatever a person goes through in stored in golden pages in the brain as part of on'es memory.
