Frontal curve

Bruner et al., AJPA 2013Modern humans are supposed to have a bulging frontal squama, but little quantitative evidence is available on this topic. Most analyses included the browridge, the rest of the vault, or the whole skull, possibly confounding factors associated with the spatial relationships of the frontal bone with the other cranial elements. After the analyses of the frontal width and of the parietal curve in the human genus, here’s a quantitative approach to the curvature of the frontal squama (Am J Phys Anthropol 2013). Modern humans do actually have a more bulging frontal bone, independently upon orientation or position of the squama. Nonetheless,  there is some overlapping between modern and extinct variation, suggesting caution when dealing with single specimens. Early modern humans display the same degree of frontal curvature than living modern humans.

  • Selective brain cooling in modern humans
    The human brain is the most expensive and costly organ in terms of energetic resources and management. However, the current understanding of its sophisticated thermal control mechanisms remains insufficient. Wang et al., 2016, have reviewed the most recent studies on brain thermoregulation and examined the anatomical and physiological elements associated wit […]

  • 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 […]
