Memory consolidation is a human-made conceptual model that maps the natural process by which initially labile memories are stabilized into long-lasting storage. Parameters: (1) synaptic consolidation — cellular mechanisms (protein synthesis, AMPA receptor insertion) operating over minutes to hours at individual synapses, (2) systems consolidation — progressive reorganization of memory traces from hippocampal dependence to neocortical storage over months to years, (3) sleep-dependent reprocessing — offline replay during slow-wave and REM sleep that strengthens consolidated traces. Persistence mechanism: scientific literature, neuroimaging protocols, textbook teaching, and the experimental replication norms of cognitive neuroscience.

Definition
Why it is in scope
A human-constructed model describing the transformation of labile memories into stable long-term representations. The model partitions consolidation into two tiers — synaptic consolidation (local, minutes to hours, mediated by protein synthesis at synapses) and systems consolidation (distributed, hours to years, involving cortical reorganization). The concept persists through empirical paradigms (retrograde amnesia gradients, sleep-dependent reactivation), computational models of synaptic plasticity, and clinical frameworks for memory disorders.

Remove test: remove memory consolidation and episodic memory stops operating — without consolidation, no episodic traces are stably stored, so there is nothing for the retrieval system to operate on. This is a present-tense operational dependency, not meta-level (not about language/cognition). Episodic memory's core function (retrieving past events) requires consolidation to produce storable traces.

Spaced repetition as a learning technique was developed based on the mechanism of memory consolidation. The technique DERIVED_FROM understanding how memory consolidation operates — repeated recall at spaced intervals leverages consolidation to strengthen retention. Which came first: memory consolidation (biological mechanism) predated the spaced repetition technique.
