Researchers have developed a computer model that mimics how the hippocampus stores new episodic memories without erasing old ones. The model shows that the CA3 region of the hippocampus serves as an anchor point for memories, allowing efficient storage in surrounding regions.
The findings reveal insights into how the brain organizes personal experiences and maintains stability despite constant updates. The model demonstrates that the hippocampus can reliably store sequences after a single presentation without destroying previous memories.
Episodic memory allows individuals to store unique personal experiences in a temporal and spatial context, forming a foundation for personal identity. The study redefines the function of the hippocampal CA3 region, suggesting it acts as an anchor for memories rather than storing them directly.
The model maintains memory stability by organizing new experiences without disrupting existing ones, akin to adding books to a well-organized library.
