Do you work on surface MRI such as HCP data? Our paper is finally out in Imaging Neuroscience, showing biases in surface fMRI. The revised ms has many new insights! TLDR: Vertices are much closer to each other in sulci, resulting in (fake) high spatial autocorrelation. (1/5)

2.5 years after ‘the great debate’ at ASSC Amsterdam, we revisit it: Lamme, @standehaene.bsky.social , @smfleming.bsky.social , Boly and @anilseth.bsky.social present their theories, and Melloni and myself try to extract some insights and criticisms. >>> www.sciencedirect.com/science/arti...

Is scientific intuition real? One definition: a scientist has good intuition if they design experiments which yield important results without necessarily being guided by an underlying theory. They "just know" what to do. I think a lot of what we call intuition is basically luck.

If you take a standard neuron model (e.g., leaky integrate-and-fire) and you expose it to Poisson inputs, you generally get a non-Poisson output spike train. So why are neural spike trains approximately Poisson?

What if… spontaneous neural activity 🧠 reflects the baseline rumblings of a brainwide dynamical system initialized for learning? We find that the rumblings have macroscopic properties like those emerging from linear symmetric, critical systems 🧵 #neuroscience #neuroAI www.biorxiv.org/content/10.1...

Pre-print 🧠🧪 Is mechanism modeling dead in the AI era? ML models trained to predict neural activity fail to generalize to unseen opto perturbations. But mechanism modeling can solve that. We say "perturbation testing" is the right way to evaluate mechanisms in data-constrained models 1/8

The saddest news. I was fortunate to count Eleanor as a mentor for many years. She did some of the most innovative and exciting memory research in my lifetime, and was always hugely supportive of others, particularly those early in their careers. A devastating loss.

Does it even make sense to ask if AI has killed Marr's three levels of analysis, if Marr's framework is a product of our own thinking, one of many possible ways to understand a system that is multiscale in nature? We (@christopherjwhyte.bsky.social and I) summarise our thoughts here below!🤗

The issue is perhaps this: biological neurons are cells, artificial neurons are just a piece of code. H1: this difference doesn't matter as all computation is done by weights & spiking patterns H2: this difference matters, as weights & spiking are just one aspect To me, this is far from settled.
