Weaker navigation signals may reflect instability in older adults
An observational study using virtual navigation and brain scans in 85 older adults linked steadier directional activity patterns to stronger signals.An observational study using virtual navigation and brain scans in 85 older adults linked steadier directional activity patterns to stronger signals.
Preprint: cross-sectional · 85 peopleMechanisms
Who was studied85 older adults
What changedMore stable directional activity patterns were associated with stronger signals in a brain region involved in navigation
The catchBrain scans measured a proposed marker of grid-cell activity, not grid cells themselves
