The target article (Arbib, 2015), henceforth TA, had as its main title Towards a Computational Comparative Neuroprimatology. This unpacks into three claims: Comparative Primatology: If one wishes to understand the behavior of any one primate species (whether monkey, ape or human -TA did not discuss, e.g., lemurs but that study could well be of interest), one will gain new insight by comparing behaviors across species, sharpening one's analysis of one class of behaviors by analyzing similarities and differences between two or more species. Comparative Neuroprimatology: This adds the challenge of comparing brains across primate species and seeking to relate comparisons of brain and of behavior. Computational Comparative Neuroprimatology: Here the aim is to go beyond informal analysis of brainbehavior relations, using computational modeling to assess the contributions of specific brain regions or neural circuitry to a class of behaviors in one species, proceeding thence to offer a more detailed analysis of how neural similarities/differences across species can enrich our understanding of behavioral similarities/differencesWe may see this as an important subclass of computational neuroethology, providing a particular perspective on ethology, the study of animal behavior more generally. Much current neuroscience uses genetically modified mice to explore neural mechanisms, so future work may increasingly consider mice as "honorary primates"but this observation points up a major lacuna in the TA and the commentaries, namely the role of genetics. However, we do extend the study "upwards" from studying the brain and body of a single individual to the study of social interactions.The subtitle Framing the Language-Ready Brain offers an interlocking set of case studies to exemplify computational comparative neuroprimatology.
