Functional craniology

Bruner et al (Front Neuroanat 2014)Chet Sherwood and Suzana Herculano-Houzel are editing a Frontiers volume entitled “The Human Brain’s Place in Nature: Evolution of Large Brains”, cross listed between Frontiers in Neuroanatomy and Frontiers in Human Neuroscience. There you can find review and research papers dealing with pros and cons of evolving large brains. Our article presents issues in functional craniology, with topics joining evolution and medicine. The article begins with an introduction to functional craniology and brain-braincase structural relationships. Features associated with sutures and brain spatial organization are interesting in evolutionary neuroanatomy and in surgery as well. Brain thermoregulation is a major factor in both fields, and modelling can help to test the influence of brain form changes in heat dissipation patterns. Changes in the frontal lobes proportions and position during human evolution are discussed as a probable background for visual impairment, in particular myopia, because of spatial conflicts between brain and orbits. The dilation of the parietal areas in modern humans and the complexity of the deep parietal elements are then integrated with information on neurodegenerative processes, in particular Alzheimer’s disease, in an evo-neuro perspective. Evolutionary neuroanatomy and medicine share information, tools, methods, and samples, being interested in the same characters and processes for different reasons and different targets. Functional craniology is the bridge we use to integrate these fields.

  • Fossil Primate Brains
    Primates are unique among mammals for having a brain much larger than expected for body size. An important  aim in paleoneurology is  understanding how cerebral structures reorganized to accomodate primate cerebral expansion. The brain comprises only soft-tissue and does not fossilize  so paleoneurologists rely on endocasts, either physical or digital molds […]

    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 […]
