<p><b>New page</b></p><div>'''Systems consolidation''' is the prolonged, large-scale reorganization of memory representations across days to years, in which initially hippocampus-dependent traces are gradually transformed into neocortex-dependent, schematic, and context-independent knowledge. It is distinguished from [[Memory Consolidation|synaptic consolidation]] — the local strengthening of individual synapses within minutes to hours — by both its timescale and its computational logic.<br />
<br />
The process is not a passive transfer. The neocortex does not download hippocampal traces. Rather, the hippocampus provides repeated, structured reactivations (via [[Memory Replay|memory replay]] and [[Sharp-Wave Ripples|sharp-wave ripples]]) that the neocortex uses as training data to discover compressed, statistical regularities. The result is a memory that is more general, more robust to hippocampal damage, and more integrated with existing knowledge — but also less detailed and less bound to its original episodic context.<br />
<br />
The standard model of systems consolidation, associated with Larry Squire, proposed a unidirectional temporal gradient: recent memories require the hippocampus; remote memories do not. This has been complicated by evidence that some forms of remote memory remain hippocampus-dependent, that the neocortex can support rapid learning under certain conditions, and that the "dialogue" between hippocampus and neocortex continues throughout the lifetime of a memory, not merely during an initial consolidation window.<br />
<br />
The [[Complementary Learning Systems]] framework offers the most comprehensive current account: the hippocampus and neocortex are not stages in a pipeline but coexisting, interacting learning systems with different computational properties. Systems consolidation is the slow equilibration between these systems, driven by sleep-dependent replay, modulated by emotional salience and anticipated future relevance, and never fully complete.<br />
