👁️🧠🧪 Vision takes time. But how does visual information flow through the human brain? Our new PLOS Computational Biology paper uses population receptive field (pRF) modelling to bring the spatial precision of fMRI to MEG, revealing the temporal dynamics of visual areas. 📖 doi.org/10.1371/jour...

Non-invasive mapping of the temporal processing hierarchy in the human visual cortex

Author summary Vision doesn’t happen instantaneously, but unfolds over time. While we understand a lot about how the brain processes visual space, understanding how the brain processes information ove...

In sports, we celebrate 1st, 2nd, 3rd. Everyone else gets lumped together. Why? Using 7T MRI, pRF modelling, and artificial neural networks, we show that tuning underlies ordinality perception, with most neural populations preferring early ordinalities. doi.org/10.1523/JNEU... 🧪🧠

Neural tuning for ordinal processing: convergent patterns in human brains and artificial networks

Processing ordinality, i.e., the rank of an item in a series such as 1st, 2nd, 3rd, etc., is a fundamental skill shared by humans and animals. While humans often use symbolic sequences like numbers or...

Excited to share that my first article is now published in Communications Biology! Humans and many animals have an innate ability to rapidly perceive numerosity—the number of objects in a visual scene. But how does our brain process this fundamental capability? Read the full paper: rdcu.be/eRxMi

Numerosity adaptation suppresses monotonic neural responses to numerosity displays in the early visual cortex, with more suppression for higher numerosity adaptors. Therefore, numerosity adaptation effects begin in early sensory stages of processing. www.nature.com/articles/s42...

The paper demonstrating that #psilocybin alters contextual computations is out in @natcomms.nature.com : doi.org/10.1038/s414... Thanks to the reviewers and coauthors : @marcoaqil.bsky.social , @tknapen.bsky.social , @gillesdehollander.bsky.social , and Nina Vreugdenhil

Psilocybin alters visual contextual computations - Nature Communications

This study finds psilocybin alters visual contextual brain processes and perception, suggesting a generic mechanism through which psychedelics influence brain function and subjective experience.

Psilocybin, the active compound in magic mushrooms, alters perception and induces hallucinations. In this preprint, we show through visual illusions, fMRI and modeling that psilocybin affects contextual computations, a potentially general mechanism of psychedelics. www.biorxiv.org/content/10.1...

Excited to share our new paper w/ @cibaker.bsky.social in @natcomms.nature.com linking active vision & memory! We provide evidence that gaze reinstatement & neural reactivation are deeply related phenomena that jointly reflect the experiences constructed during recall. doi.org/10.1038/s414... 🧵1/9

Thanks to all (co)authors & reviewers for their contribution to this study on #layer specific changes in #sensory #cortex across the #lifespan in #humans & #mice now out in @natneuro.nature.com Here is a short summary of our findings 1/6

🧠 The human brain ages less than thought and in layers – at least in the area of the cortex responsible for the sense of touch. See study @natneuro.nature.com by @estherkuehn.bsky.social and colleagues at DZNE, @hih-tuebingen.bsky.social and @uni-magdeburg.de: 👉 www.nature.com/articles/s41...
