Asymmetries

Brain asymmetries have always been a hot topic in neurosciences. Differences are often so subtle, and there are still many disagreements on this issue. If this topic is difficult to investigate in living species, when analyzing fossil taxa doubts are much more than certainties. In a recent paper Balzeau and colleagues quantify the hemispheric fronto-occipital projection in modern humans, African apes, and fossil hominids, analyzing fluctuating asymmetry, directional asymmetry, and antisymmetry. Differences between groups in distribution and variation are small, and generally related to the degree of asymmetry, not to the presence or combination of characters. It seems that differences between modern humans and apes (and fossil hominids) are a question of grade. Once more, it seems that on this issue the information available from the general endocranial morphology is necessary, but very limited.

  • Parietal lobes and tool use
    The parietal lobe has a unique central location in the brain, and it is involved in higher cognitive functions. Investigating its functions and connectivity is essential to understand its role in uniquely human abilities. Two recent works have put emphasis on the importance of the parietal lobe for tool use. Catani and colleagues investigated the […]

    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 […]
