In a recent review, @adekstreme.bsky.social and I revisit how spatial navigation breaks down in aging and early Alzheimer’s disease - and why it’s not just about the brain.

New paper alert! 🚨 We show that age-related neural dedifferentiation in scene-selective cortex is tied to changes in eye movements. Using simultaneous fMRI + eye-tracking, we found that younger adults’ fixations covary with scene specificity, but this link weakens with age.

In a new preprint, we show that age differences in navigation strategies are complex & not well explained by the traditional allocentric-egocentric dichotomy. One unexpected finding - young adults shifted towards more 'egocentric' strategies when navigating in immersive and ambulatory VR environment
Age differences in spatial navigation stem from a preference for familiar routes rather than impaired landmark-dependent strategies: http://osf.io/b7n6s/
