Pan & Pan

Although geometric morphometrics is currently the most promising method to analyze endocasts, there are alternatives. Durrleman and colleagues propose an approach based on deformations between surfaces. This method can help with non-linearity of the ontogenetic processes, lack of morphological references, or continuity of the anatomical tissues. The approach is definitely more complex and less intuitive than geometric morphometrics. This may mean sometimes more analytical power, sometimes more analytical bias.  The case-study is the endocranial ontogeny in chimps and bonobos: some shared patterns, but interesting differences too.

Deep asymmetries

Stephanie Bogart and colleagues have published an interesting study on sulci asymmetries in chimps and macaques, on NeuroImage. Quantifying cortical depth and surface area, they found consistent  population-level brain asymmetries in chimpanzees but not in macaques. The paper is a good review on many issues related to brain asymmetries and evolution in primates. Asymmetries that, however, are the results of mechanisms and processes which are still poorly known.

Primate brain

There is a special issue of Progress in Brain Research entitled “Evolution of the Primate Brain”, edited by Hofman and Falk. There are papers by Sherwood, De Sousa, Zollikofer, Schoenemann, Kaas, Cherniak, Buxhoeveden, and many others. Topics include hominin brain evolution, encephalization, cranial ontogeny, brain and language, intelligence, neural wiring, histology, prefrontal cortex, cerebellum, insula, lateralization, genetics, and much more. Have a look:

    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 […]
