Fig. 1. a. Visual and auditory regions of interest (ROIs). b. Responses in a combination of visual (e.g., early dorsal visual stream; Fig. 1a, middle panel) and auditory regions were used to predict responses in the rest of the brain using MVPN. c. In order to identify brain regions that combine responses from auditory and visual regions, we identified voxels where predictions generated using the combined patterns from auditory regions and one set of visual regions jointly (as shown in Fig.  1b) are significantly more accurate than predictions generated using only auditory regions or only that set of visual regions.

πŸŽ‰New Paper Alert!πŸŽ‰

Really excited that this collaboration is finally out! It shows that combining oscillatory dynamics with hierarchical predictive frameworks generates speech perception that is robust to temporal distortions: similarly to human behavior and more so than current ASR models.

Our cognitive maps of the environment contain hierarchical structure, with some spaces nested in others.

Behavioral responses and brain activity in scene-responsive regions reflect this hierarchical structure.
