The most striking, interesting, yet poorly understood gross morphological features of the
cerebral hemispheres in mammals are the diverse and complex arrangements of their …

The evolution of the brain in mammals has been accompanied by a progressive
enlargement of the cerebral cortex. Allometric analysis of the volume, surface and …

An OBVIOUS, yet remarkable, feature of mam-malian brains is that the cortex varies so much
in size. As a curved, often folded complexly, sheet of tissue, its surface ranges from 3-5 cm2 …

A model of cortical folding in mammals is presented. The model consists of a cube,
superimposed on which are straight close-packed gyri, running the length of the cube. The …

One of the most prominent features of the human brain is the fabulous size of the cerebral
cortex and its intricate folding. Cortical folding takes place during embryonic development …

There is a basic rule to mammalian neocortical expansion: as it expands, so does it fold. The
degree to which it folds, however, cannot strictly be attributed to its expansion. Across …

During development the human cortex changes from a smooth lissencephalic structure to
one that is highly convoluted. Increases in the degree of cortical folding are associated with …

Controversy over the placement of the lunate sulcus on the Taung australopithecine
endocast has been central in the debate as to whether cortical reorganization occurred …

Understanding the evolutionary forces that produced the human brain is a central problem in
neuroscience and human biology. Comparisons across primate species show that both …

During evolution, the mammalian cerebral cortex has expanded disproportionately to brain
volume. As a consequence, most mammals with large brains have profusely convoluted …
