How Memory Really Works

Memory is far stranger than a filing cabinet. It is an active process, not a stored object — built, rebuilt, and reshaped each time you use it:

• Built from attention: only what you focus on during encoding forms a lasting neural pattern.
• Cemented by sleep: the hippocampus replays the day during slow-wave sleep, moving memories to the cortex.
• Rewritten by recall: every time you remember something, you can quietly edit it, and small errors compound.
• Vulnerable to suggestion: convincing false memories can be planted, and your brain cannot flag them as fake.
