Electrodermal archaeology

After all those surveys on parietal lobes and parietal evolution, some years ago we began investigating some functions particularly associated with the parietal cortex, and generically labeled as visuospatial integration. Some visuospatial behaviors can be inferred in fossils, according to anatomical and archaeological evidence. In my lab, we are interested in aspects bridging cognition, body, and tools. In a recent paper published in Progress in Brain Research we have applied electrodermal analysis to investigate the cognitive response during a haptic experience with stone tools. Electrodermal signals have been employed here to evaluate changes in emotion and attention during stone tool manipulation, as to evidence whether different tools exert different cognitive responses when handled. New methods for cognitive archaeology!

The paper is part of a volume entitled “Cerebral Lateralization and Cognition: Evolutionary and Developmental Investigations of Behavioral Biases“, edited by Gillian Forrester, William Hopkins, Kristelle Hudry and Annukka Lindell.

  • Primate brain folding
    A recent work, analyzing the development and evolution of the primate cortical folding, evidences two separate folding processes of the neocortex. Namba and colleagues examine two subtypes of neocortex, the dorsal isocortex, defined as the portion of neocortex limited laterally by the lateral fissure (LF) and medially by the cingulate sulcus (CiS), and the p […]

  • Researchers develop non-invasive deep brain stimulation method
    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 […]
