Memory may not work how we thought, study of mice in artificial hibernation finds - Live Science

A study of mice in artificial hibernation suggests that long-term memory relies on high-level topological patterns in brain connectivity rather than individual, strong neural links. This challenges previous assumptions about how memories are physically stored and pruned during metabolic slowdowns.
Why it matters
Understanding the fundamental mechanisms of memory could lead to breakthroughs in treating neurodegenerative diseases and cognitive disorders.
A new study induced artificial hibernation in lab mice and may have revealed something fundamental about the nature of memory.
