Researchers have developed Topo-Omni, a novel deep topographic multimodal model that maps visual, auditory, and language processing onto a single contiguous surface. This model, fine-tuned from a pretrained foundation model with a spatial smoothness objective, demonstrates that a unified spatial principle can organize representations across different modalities and processing stages. The model's clusters align with human neuroimaging data, and selectively activating or suppressing these clusters can bias or impair perception, mirroring findings from human intervention studies. Topo-Omni was also used to identify new in-silico clusters, which were subsequently validated in human data, offering testable hypotheses about cortical organization. AI
