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/10.1101/… 🧵 1/n

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

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

Our review on the theoretical status of oscillations and field potentials is out! What are their causal effects, and what can electrophysiology signals reveal about how the brain works? w/ @dlevenstein @prokraustinator Bradley Voytek @_rdgao cell.com/trends/cognitive-sc…

Processes and measurements: a framework for understanding neural oscillations in field potentials

Various neuroscientific theories maintain that brain oscillations are important for neuronal computation, but opposing views claim that these macroscale dynamics are ‘exhaust fumes’ of more relevant...

🧵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/10.1101/…

Saccade onset, not fixation onset, best explains early responses across the human visual cortex...

Visual processing has traditionally been investigated using static viewing paradigms, where participants are presented with streams of randomized stimuli. Observations from such experiments have been...

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/status/1…

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/s41562-0…

Distributed representations of behaviour-derived object dimensions in the human visual system

Nature Human Behaviour - Contier et al. show that dimensions are superior to categories at predicting brain responses to visual objects.

Why do varied DNN designs yield equally good models of human vision? Our preprint with @michaelfbonner shows that diverse DNNs represent images with a shared set of latent dimensions, and these shared dimensions turn out to also be the most brain-aligned. arxiv.org/abs/2408.12804

Universal dimensions of visual representation

Do neural network models of vision learn brain-aligned representations because they share architectural constraints and task objectives with biological vision or because they learn universal...

Tuesday 27th (11:30 Aussie time) I'll share some initial results on my project on neural representations in the macaque visual system. Work with @martin_hebart & others. Check out my talk if you're at @biomag2024. And I'll be around in Sydney until 10th Sept if you want to chat!
