Domesticated bodies

Humans are hypothesized to have undergone a process of self-domestication, associated with reduction of aggressive behavior and enhanced sociability. We have also undergone anatomical changes in our parietal cortex, which is crucial for body cognition and visuospatial integration. In a recent Opinion Paper published in Frontiers in Psychology, Ben Gleeson and I wonder whether these two factors, self-domestication and body cognition, may have reciprocal influences, or even share some evolutionary mechanisms. A first likely bridge is our heightened use of technology, which is strictly associated with our body-tool prosthetic capacity and with our special life-cycle (adolescence and creativity, longevity, post-reproductive stages, etc.). The concept of “tool” is considered, in this article, through functional and cognitive parameters. A second connection is the social system, because body cognition and the association cortex affect group size and social skills based on egocentric perspectives. Neural plasticity could represent an important organic link between these anatomical and behavioral aspects. The article is part of a volume dedicated to Self-Domestication and Human Evolution.

Visuospatial behaviours

After the perspective paper on visuospatial cognition and human evolution, and the review on visuospatial integration and the fossil record, we have now published a review article on visuospatial behaviors in archaeology. Here, we introduce and discuss parietal cortex evolution, embodiment, tool use and tool making, wayfinding, and the association between physical, chronological, and social spaces. A main target of cognitive archaeology is to test whether modern human cognition is due to a specific prosthetic capacity that enhances the functional relationships between body and technology, offloading brain functions and outsourcing information process to the enviroment. Something similar happens to … spiders! This chapter is part of a book dedicated to the Evolution of Primate Social Cognition (Springer).

  • Frontal bone, parietal bone
    The skull provides a protection for the brain, and thus its composition and structure are of interest in biomechanics, for biomedical engineers and … for the Army too. Cranial vault bones consist of three layers of bone tissue – the inner and outer tables that are made of cortical bone tissue, and the cancellous bone […]

    Researchers at MIT have developed a new method of electrically stimulating deep brain tissues without opening the skullSince 1997, more than 100,000 Parkinson’s Disease patients have been treated with deep brain stimulation (DBS), a surgical technique that involves the implantation of ultra-thin wire electrodes. The implanted device, sometimes referred to as […]
