Based on modeling gyrification as a reaction-diffusion process, the authors provide a mechanism — compatible with the sulcal roots hypothesis — by which the folding process of the cerebral cortex can be explained, along with its anatomical variability and common malformations like polymicrogyria and lissencephaly.
Provides an analysis of correlations between 10 volume-based brain morphometric measures and 32 single-nucleotide polymorphisms in 25 schizophrenic patients, tentatively identifying RELN, the gene encoding reelin, as possibly involved in ventricular enlargement, and PCDH12, the gene encoding protocadherin 12, as a candidate for genetic invovlvement in gyrification.
A histological study with a good overview over the history of the study of the insula.
Demonstrates that neural precursor cells in ß-catenin-transgenic mice undergo more cell divisions before finally differentiating. This resulted in an increase of cortical surface area without an accompanying change in cortical thickness.

In comparison to rodents, "...substantially more total rounds of cell division elapsed during the prolonged neurogenetic period of the monkey cortex, providing a basis for increased cell production."

One of the few non-invasive in vivo studies of gyrification prior to the wide-spread adoption of MRI.
