Corpus callosum and allometry

Size and shape variations of the human corpus callosum have always been controversial. Limits in samples and techniques have not helped in this sense. This month we have published a paper on midsagittal shape variation of the corpus callosum. Taking into account the results of this analysis, it seems that the shape differences between males and females are largely allometric. That is, they are secondary consequences of size variation, and not sex-related characters. Differences between groups are, however, very small, mostly because of the large personal differences among individuals. This is probably also due to a limited morphological integration within the corpus callosum, which is influenced by different and independent factors along its outline. It remains to be understood when shape variation is due to intrinsic components of the corpus callosum, and when it is due to indirect influences of external structures.

    A new PhD student in the team working on craniovascular anatomy! Stanislava Eisová was in our laboratory few years ago, publishing a paper on parietal bone and vessels in which she investigated correlations between craniovascular morphology, skull size, and bone thickness. She got a Master Degree in Anthropology of Past Populations at the University of […] […]

  • 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 […]
