kuhn-sol-i-DAY-shuhn
/kənˌsɒlɪˈdeɪʃn/
The biological process by which fresh, fragile short-term memories are stabilized into durable long-term memory.
Emphasizes the neural stabilization period, often occurring during sleep, when memories become resistant to interference.
The story behind the word. From Latin 'consolidare', combining 'con-' (together) and 'solidus' (solid, firm). Late 19th-century neuroscientists borrowed the term to describe how newly formed, fluid memory traces become physically solid in brain tissue.

Example sentences
- "Slow-wave sleep plays a critical role in memory consolidation, transferring neural traces from the hippocampus to the neocortex." Neuroscience
- "Without adequate rest after studying, the process of memory consolidation is disrupted, causing rapid forgetting." Cognitive psychology
Memory hook
CONSOLIDATION turns delicate memory traces into CONCRETE, solid pathways. Make memory solid.
When not to use
Do not use when simply describing saving a digital computer file.
Fun facts
- Disrupting memory consolidation right after learning can permanently erase a memory trace before it ever reaches long-term storage.
