Dynamic interplay of early- and late-born neurons influences memory persistence
Research reveals that the dynamic recruitment of developmentally distinct hippocampal neurons plays a crucial role in the persistence and plasticity of memories. Early-born neurons contribute to long-term memory stability, while late-born neurons are involved in recent memory retrieval. These findings highlight the complexity of memory processing and how different neuron populations are sequentially recruited to support memory evolution over time.

The brain creates three distinct copies for each memory
Researchers from the University of Basel have discovered that the brain stores each memory in three separate copies across different neural networks. This redundancy ensures that memories can be recalled even if one network is compromised. The findings highlight the brain’s intricate strategy for preserving important information and maintaining cognitive resilience.
Human brain stores memories in three distinct copies
New research has revealed that the human brain stores memories in three separate copies within different regions. The study found that the hippocampus, entorhinal cortex, and perirhinal cortex each store a distinct version of the same memory, suggesting a more complex and redundant system of memory storage than previously understood. This redundancy might play a crucial role in memory stability and retrieval, particularly in cases of brain damage or neurodegenerative diseases. Understanding this system could lead to improved treatments for memory-related conditions.
