How is high-level visual cortex organized? In a new preprint with @martin_hebart & @KathaDobs, we show that category-selective areas encode a rich, multidimensional feature space 🌈 biorxiv.org/content/10.110… 🧵 1/n

@kasper_vinken We suggest this reflects unique multidimensional tuning profiles and not just stronger responses along a single axis. So, a form of sparse tuning to key dimensions, as shown in this paper: doi.org/10.1038/s41562…

@kasper_vinken By “discrete” category selectivity, we refer to cortical patches that respond preferentially to specific categories like faces or bodies. Even though these categories share many features, the patches show distinct, specialized responses. ...

@Qiu_Han_ @martin_hebart @KathaDobs Thanks, Qiu! 😊

@levandyck @martin_hebart @KathaDobs Congrats! Nice to see it out 🥳

This work resonates with recent proposals by @meenakshik93, @talia_konkle, @_jacobprince_, @Chris_I_Baker, @jbrendanritchie, @OliverContier, and many others. Check out the preprint for details. We’d love to hear your thoughts! 11/11

This multidimensional framework supports both discrete category selectivity and continuous feature integration, offering a unified account of high-level visual cortex organization. 10/n

🧵Join us for a short tour of how a large-scale MEG dataset collected during active vision made us question it all. New work with @carmen_amme @PhilipSulewski @EelkeSpaak @martin_hebart @konigpeter biorxiv.org/content/10.110…

How does our brain allow us to make sense of our visual world? Work led by @OliverContier w/ @Chris_I_Baker now out in @NatureHumBehav provides support for a theoretical framework of behaviorally-relevant selectivity beyond high-level categorization. 🧵 x.com/OliverContier/…

Hugely excited that this work with @martin_hebart and @Chris_I_Baker is now out in @NatureHumBehav !!! By moving from a category-focused to a behaviour-focused model, we identified behaviourally relevant object information throughout visual cortex. nature.com/articles/s4156…
