After our first paper introducing thermal maps on endocasts (Am J Hum Biol 2011), now we present some ideas to quantify and compare thermal dissipation patterns (Am J Hum Biol 2012). Although brain thermoregulation is not only a matter of size and shape, we can anyway evaluate the influence of geometry on heat distribution. Such morphological correlate can provide some information on brain physiology in fossils. Size is probably the main factor influencing thermal management. Nonetheless, local differences associated with changes in proportions or spatial organization can be relevant.

  • 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 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 […]
