This paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!

Memory problems will change how you see the world...literally 👀 Across two new papers, we examined the eye movement patterns of younger adults, older adults, individuals with mild cognitive impairment, and amnesic cases. 1/5

The brain represents the world around us as a series of neural states - stable patterns of activity that change as we move from one event to the next. New paper by @selmalugtmeijer.bsky.social showing that neural states get longer as people age. #PsychSciSky nature.com/articles/s42003-025-08792-4

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. Link in post below 👇

I'm thrilled that my first first-author paper in @fnim-lab.bsky.social is now out! We found that whole-brain cortical volume predicted the strength of neural reinstatement of scene information in the parahippocampal and medial place areas (PPA & MPA in the figure below). (1/2)

I'll admit, I was skeptical when they said Gemini was just like a bunch of PhDs. But I gotta admit they nailed it.

We built the simplest possible social media platform. No algorithms. No ads. Just LLM agents posting and following. It still became a polarization machine. Then we tried six interventions to fix social media. The results were… not what we expected. arxiv.org/abs/2508.03385

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:

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. www.nature.com/articles/s41...

🧠 Paper out! We investigated how hippocampal and cortical ripples support memory during movie watching. We found that: 🎬 Hippocampal ripples mark event boundaries 🧩 Cortical ripples predict later recall Ripples may help transform real-life experiences into lasting memories! rdcu.be/eui9l

Despite recent criticism from Quiroga to our claim that Concept Neurons emerge from Conjunctive Coding Neurons we claim: “And yet, the hippocampus codes conjunctively!”. We hope it sparks a smile (and maybe a few debates). Read here: tinyurl.com/3ycv3vj2

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.

Your brain doesn’t just passively track time ⏳ - it structures it. In @Science.org we show that activity in 🧠 memory circuits (LEC) drifts constantly, but makes sharp jumps at key moments, segmenting life into meaningful events. (1/2) 👉 www.science.org/doi/10.1126/...

There is no binding problem because vision—and cortex more broadly—is not modular. Phrenological theories create phrenological artifacts. Beyond binding: from modular to natural vision doi.org/10.1016/j.ti... #neuroscience

🧠✨How do we rebuild our memories? In our new study, we show that hippocampal ripples kickstart a coordinated expansion of cortical activity that helps reconstruct past experiences. We recorded iEEG from patients during memory retrieval... and found something really cool 👇(thread)

Many neuroscience students are steeped in an experiment-first style of thinking that leads to “random walk science.” Let’s not forget how theory can guide experiments towards deeper insights, writes @gershbrain.bsky.social. #neuroskyence www.thetransmitter.org/theoretical-...

HOT OFF THE PRESS - Back in 2019 we started asking ourselves what could you to demonstrate where werable, OPM-MEG technology could fit into naturalistic #neuroskyence. One snag, we'd have to build the system from scratch first... Anyway its 2025, read the paper here -> doi.org/10.1162/imag...
