Summary

Story summary

Stanford University researchers link aging to impaired spatial navigation, tracing it to chaotic grid-cell firing in the medial entorhinal cortex (MEC).
Older mice struggle to adapt to changes; young and middle-aged mice adapt quickly.
The study identifies 61 genes linked to grid-cell stability, including Hapln4, with a resilience seen in a 'super-ager' mouse.
