Neurocracy

After giving (too) much importance to brain size for more than one century, we are now focusing our attention on functions, parts, and relationships. Nonetheless, the many recent papers by Suzana Herculano-Houzel stress that size matters, indeed. More than size per se, what is definitely relevant is the number of neurons. The number of “computational units” in mammals, primates, or hominids, is incredibly correlated to many biological factors. Patterns are amazingly constant, and linear. After estimations on the number of neurons in fossil hominids, now a recent paper considers the relationships between brain size, metabolism, and foraging. The models developed by using the available information on primates strongly support the theory that the human genus could have had the possibility to increase brain size only thank to food preparation. Otherwise, we should spend all the day searching for something to eat, to maintain such a brain budget!

  • 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 […]
