New paper! 🚨 ~1.8K Mooney images from THINGS + ~1K participants to study visual ambiguity resolution.

Results suggest the visual system shifts from a top-down guess to bottom-up matching after disambiguation, and a U-shaped link between info gain and identification.

🚀 Excited to share a major update to our “Mixture of Cognitive Reasoners” (MiCRo) paper!

We ask: What benefits can we unlock by designing language models whose inner structure mirrors the brain’s functional specialization?

But to come back to focal neural effects of stimulation: without topography in the model I find it hard to see how to explicitly model the interaction of stimulation at multiple sites that might allow to obtain stronger behavioral effects than we observed using single-site stimulation.

Defining face-selective units in a non-topo model, increasing their activation level, and projecting that to the latents of a GAN used for image generation probably also results in face-related changes in model percepts. Is that more what you are asking?

This allows eg our visualizations, where we stimulate face-selective regions - defined using a standard face-localizer - which then lead to face-related changes to model percepts (Figs 5, 9-15).

Thanks, Adrian! The main purpose of using topo models is to allow the implementation of neural activation changes and their propagation across the cortical sheet using the topo model's in-silico equivalent of the cortex.

Absolutely agree that neural responses to the perturbations would have been very useful. While that type of data was not recorded in our experiments, the groups of Michael Beyeler @mbeyeler.bsky.social and Eduardo Fernandez just presented some great work in this direction: bsky.app/profile/mbey...

Thanks for the question, Konrad! Do you mean what percentage of variance of the neural effects of perturbations our topo models can explain? Would be great if we could investigate that, but we haven't recorded neural data during perturbation trials. Or what did you mean by observational data?
