用法筆記

Frequently used in scientific writing about memory research. The word is almost always pluralised (engrams) in research contexts because memory traces involve multiple neural connections. Often paired with verbs like 'form', 'store', 'reactivate', or 'identify'.

常見錯誤

❌The engram is located in one place in the brain.
✅An engram is stored across a network of brain cells.
