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.

Delighted to share our latest review in Nature Reviews Neuroscience!
We examine the growing evidence that vascular dysfunction plays a key role in cognitive decline in ageing and dementia, and argue that preserving/restoring CBF should be central to future therapies.

By integrating physical mobility and sensorimotor function into models of spatial navigation, we hope to broaden the scope of how navigation is studied, assessed, and ultimately used to detect preclinical changes in Alzheimer’s disease.

We propose that spatial navigation offers a useful lens into early cognitive-motor changes in aging, shaped by neuromodulatory and multisensory processes that may decline before overt brain pathology.

Rather than focusing solely on hippocampal or entorhinal dysfunction, we highlight how degraded sensorimotor inputs - like balance, gait, and vestibular function - play a crucial but often overlooked role.

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.

It is important now more than ever for scientists to share their work with the general public. I am pleased to have contributed to investNScience’s campaign which they are currently running across numerous social media platforms. It is a great initiative that makes science more relevant to everyone.

Instead of listing my publications, as the year draws to an end, I want to shine the spotlight on the commonplace assumption that productivity must always increase. Good research is disruptive and thinking time is central to high quality scholarship and necessary for disruptive research.

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

Look forward to reading this. This is something I have been thinking about in terms of age differences in navigation. Are older adults (on average) impaired at using a cognitive map to navigate, or do they simply prefer to exploit familiar and more certain routes?

🚨New paper alert!🚨 -- Registered report style!

A "blue-print"!

Some people seem born to explore: breaking new ground, traveling to new places.

Others seem perfectly content to enjoy familiar comforts.

This explore/exploit tradeoff is well-known, and varies across people and situations

In a recent preprint, we reviewed the many parallels between gait abnormalities and impaired spatial navigation in older age and Alzheimer's disease. Navigation may offer an ecologically valid cognitive-motor phenotype of age-related cognitive dysfunction. Feedback welcome!
