| Summary:
The world of beauty is deeply connected to the visual cortex, as perception
often begins with vision in both humans and marmosets. In this study, to
investigate their functional correspondences, we used 13 healthy human
volunteers (9 males and 4 females, aged 22-56 years) and 8 common marmosets (6
males and 2 females, aged 20-42 months). We then measured pairwise and
beyond-pairwise correlations, redundancy, and synergy in movie-driven fMRI data
across species. First, we consistently observed a high degree of functional
similarity in visual processing within and between species, suggesting that
integrative processing mechanisms are preserved in both humans and marmosets,
despite potential differences in their specific activity patterns. Second, we
found that the strongest functional correspondences during movie watching
occurred between the human peri-entorhinal and entorhinal cortex (PeEc) and the
occipitotemporal high-level visual regions in the marmoset, reflecting a
synergistic functional relationship. This suggests that these regions share
complementary and integrated patterns of information processing across species.
Third, redundancy measures maintained stable high-order hubs, indicating a
steady core of shared information processing, while synergy measures revealed a
dynamic shift from low- to high-level visual regions as interaction increased,
reflecting adaptive integration. This highlights distinct patterns of
information processing across the visual hierarchy. Ultimately, our results
reveal the marmoset as a compelling model for investigating visual perception,
distinguished by its remarkable functional parallels to the human visual
cortex.
