“…The common marmoset has become an important nonhuman primate model for bridging the translational gap between rodents and humans. Marmosets have a lissencephalic cortex, like rodents, but as primates they possess the structural and functional brain architecture that supports elaborated behaviors such as pro-social interaction (Ferrari and Digby, 1996; Huang et al, 2020; Miller et al, 2016; Saito, 2015; Yokoyama and Onoe, 2015), complex vocal communication (Choi et al, 2015; Miller et al, 2015; Sadagopan et al, 2015; Takahashi et al, 2016), and saccadic eye movements (Chen et al, 2020; Ma et al, 2020; Mitchell et al, 2014; Selvanayagam et al, 2019). This, paired with a high reproductive power, small size, and fast maturation rate, make this non-human primate (NHP) species particularly interesting for neuroscience.…”

The common marmoset has enormous promise as a nonhuman primate model of human brain functions. While resting-state functional magnetic resonance imaging (fMRI) has provided evidence for a similar organization of marmoset and human cortices, the technique cannot be used to map the functional correspondences of brain regions between species. This limitation can be overcome by movie-driven fMRI (md-fMRI), which has become a popular tool for non-invasively mapping the neural patterns generated by rich and naturalistic stimulation. Here, we used md-fMRI in marmosets and humans to identify whole-brain functional correspondences between the two primate species. In particular, we describe functional correlates for the well-known human face, body, and scene patches in marmosets. We find that these networks have a similar organization in both species, suggesting a largely conserved organization of higher-order visual areas between New World marmoset monkeys and humans. However, while face patches in humans and marmosets were activated by marmoset faces, only human face patches responded to the faces of other animals. Together, the results demonstrate that md-fMRI is a powerful tool for interspecies functional mapping and characterization of higher-order visual functions.
