The representation of visual objects in inferotemporal (IT) cortex has been intensively investigated in monkeys and humans. Here we presented monkeys and humans with the same images of real-world objects and compared the IT object representations between the species. Two images similar in the monkey-IT representation tend also to be similar in the human-IT representation and vice versa. Moreover, IT response patterns form category clusters, which match between the species. The clusters correspond to animate and inanimate objects; within the animate objects, faces and body parts form subclusters. Within each category, IT distinguishes individual exemplars and the within-category exemplar similarities also match between human and monkey. Our findings suggest that primate IT across species may host a common code, which combines a categorical and a continuous representation of objects.
