Abstract Modern neuroimaging represents three-dimensional brain activity, which varies across regions. It remains unknown whether activity within regions is organized in spatial configurations to reflect perceptual and cognitive processes. We developed a rotational cross-correlation method allowing straightforward analysis of patterns for the precise detection spatially correlated distributions activity. Using several statistical approaches, we found that seed fusiform face area were robustly involved face-specific representations. These differed from non-specific visual network meaning structure locally preserved stimulation-specific Our findings indicate representations cerebral suggest 3D coding processed information patterns. More generally, our results provide first demonstration represented transmitted as local
