Brains and endocasts

Kobayashi et al 2014In the second volume of the recent publication on dynamics of learning in Neanderthals and modern humans there are two interesting papers by Yasushi Kobayashi and colleagues on the relationships between skull, brain, and endocast. They present results from five macaques (Macaca fascicularis), comparing head, skull, brain, and endocranial mould, by traditional dissection and digital imaging. In the first article they show a remarkable correspondence between brain and endocast morphology. The principal sulci and gyri of the cortex can be easily recognized on the mould, with a reliability which is definitely encouraging for those working in paleoneurology. Of course, we know that in small brains the endocranial imprints are more evident than in large brains, and the same comparison in hominids may be more difficult. In the second paper, they analyze the correspondence between sutures and sulci (the coronal suture and the arcuate sulcus, in particular). Again, results are reassuring for those making brain inferences from fossil remains, because at least in this case the spatial relationship is constant and reliable. These are essential data in paleoneurology, and we need more studies like these, with more samples, more species, more features.

  • How to become a super memorizer – and what it does to your brain
    New research shows that we can train our brains to become memory champions To many of us, having to memorize a long list of items feels like a chore. But for others, it is more like a sport. Every year, hundreds of these ‘memory athletes’ compete with one another in the World Memory Championships, memorising hundreds of words, numbers, or other pieces of inf […]
