Temporal dedifferentiation of neural states with age during naturalistic viewing - Communications Biology
Movie fMRI data reveals age-related lengthening of neural states in visual and prefrontal regions, reflecting reduced temporal differentiation while preserved alignment with perceived events suggests stable coarse event segmentation.

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 neuroscience, we often try to understand systems by analyzing their representations — using tools like regression or RSA. But are these analyses biased towards discovering a subset of what a system represents? If you're interested in this question, check out our new commentary! Thread:

Common analyses of neural representations: Encoding models (relating activity to task features) drawing of an arrow from a trace saying [on_____on____] to a neuron and spike train. Comparing models via neural predictivity: comparing two neural networks by their R^2 to mouse brain activity.

A very cool follow-up on one of the first studies I did with @fnim-lab.bsky.social. Older adults do not gate task-irrelevant information during episodic retrieval. New data reveal that this is not due to age differences in memory strength, but may instead reflect a decline in inhibitory control.
New Paper Alert! de Chastelaine et al found that young adults are able to employ 'retrieval gating' to allow mnemonic content to be aligned with a retrieval goal, but older adults failed to do this even when their memory was boosted to match young adults! www.sciencedirect.com/science/arti...
