Today I'm posting a new blog about an astonishing scientific own goal. Hundreds of papers have reported using a totally wrong antibody to investigate the tumor suppressor p16. This mistake has happened because scientists have muddled the names of two proteins. forbetterscience.com/2026/06/02/m...

This is one of the most exciting pieces of science I have had the privilege to be involved in, led by @rui-xu.bsky.social‬, Bob Desimone, and Mark Richardson: the discovery of actual long-range monosynaptic connections in the human brain! For example the FFA connects to the rTPJ, how cool is that?

New preprint as my first post! "Monosynaptic connections link functionally similar regions in human cortex." We use electrical stimulation + fMRI in epilepsy patients to map whole-brain monosynaptic connectivity at 42 cortical sites. doi.org/10.64898/202... 1/n

For all the esteemed scholars out there who prefer gaining knowledge the correct way, here’s a summary of our upcoming opinion piece, delivered to you by Jesus himself. But seriously, science communication is about to get a lot worse and better at the same time.

After rereading the cool hidden brain paper (www.frontiersin.org/journals/sys...) I decided to make a new version. Code and everything available here: github.com/koerding/neu... Most popular: hippocampus. Why are diagonal band, medial geniculate nucleus, and interposed nucleus so unpopular?

Can whole-brain fMRI responses to naturalistic video stimuli be predicted using only transcripts? Last year, I gave a tutorial on exactly that. Since the response was very positive, I’ve now released both the tutorial notebook and the trained models publicly.

Excited to give a talk at #Cosyne2026 about my PhD work! We show that RNNs trained on visual search converge on brain-like solutions, producing primate-like behavior and neural representations. Happy to chat if you're at Cosyne! 📅 March 15, 2026 📍 Lisbon, Portugal www.biorxiv.org/content/10.1...

DNN models of the brain are getting bigger. Are we replacing one complicated system in vivo with another in silico? In new work, we seek the *smallest* DNN models of visual cortex, balancing prediction with parsimony. It turns out these compact models are surprisingly small! rdcu.be/e5H8G

1/9 New paper with @gonzalezgarcia.bsky.social and @lindedomingo.bsky.social : “Characterising semantic prioritisation in visual working memory.” Core question: when we hold visual info briefly in mind, what gets accessed first: perceptual details or semantic meaning?

Our new preprint is out on bioRxiv! @doellerlab.bsky.social We show that eye-movement sequences actively organize information by aligning with underlying structure and flexibly adapting to cognitive demands in working memory. www.biorxiv.org/content/10.6...

Excited to see what comes out of it. Having worked on a similar problem during the Algonauts Challenge, I was quite surprised by the results in the paper.

This is significantly lower than the paper's reported number and far below gpt2-xl (which in the paper is outperformed by oasm). So something does not track here, either in the preprint's re-implementation of the benchmark or my reconstruction of the model.

neuroAI comparisons of ANNs to brains do have a range of problems. Even more than I had realized. And I was worried before: www.biorxiv.org/content/10.1...
