Reply to Barton and Montgomery: A case for preferential prefrontal cortical expansion. [PDF]

Proc Natl Acad Sci U S A, 2019
In our article (1), we focus on prefrontal cortex (PFC) to ( i ) arrive at a surface-based delineation of PFC using modern architectonic and functional criteria; ( ii ) determine its absolute size in humans, macaques, and chimpanzees in terms of gray and white matter volumes analyzed using structural MRI data from many subjects; and ( iii ) compare PFC

Variable functional connectivity architecture of the preterm human brain: Impact of developmental cortical expansion and maturation. [PDF]

Proc Natl Acad Sci U S A, 2020
Functional connectivity (FC) is known to be individually unique and to reflect cognitive variability. Although FC can serve as a valuable correlate and potential predictor of (patho-) physiological nervous function in high-risk constellations, such as ...

Laplace-Beltrami eigenfunction expansion of cortical manifolds [PDF]

2011 IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2011
We represent a shape representation technique using the eigenfunctions of Laplace-Beltrami (LB) operator and compare the performance with the conventional spherical harmonic (SPHARM) representation. Cortical manifolds are represented as a linear combination of the LB-eigenfunctions, which form orthonormal basis.

Dynamic patterns of cortical expansion during folding of the preterm human brain. [PDF]

Proc Natl Acad Sci U S A, 2018
Significance The human brain exhibits complex folding patterns that emerge during the third trimester of fetal development. Minor folds are quasi-randomly shaped and distributed. Major folds, in contrast, are more conserved and form important landmarks.

Greater addition of neurons to the olfactory bulb than to the cerebral cortex of eulipotyphlans but not rodents, afrotherians or primates

Frontiers in Neuroanatomy, 2014
The olfactory bulb is an evolutionarily old structure that antedates the appearance of a six-layered mammalian cerebral cortex. As such, the neuronal scaling rules that apply to scaling the mass of the olfactory bulb as a function of its number of ...

Cellular scaling rules for the brain of afrotherians

Frontiers in Neuroanatomy, 2014
Quantitative analysis of the cellular composition of rodent, primate and eulipotyphlan brains has shown that nonneuronal scaling rules are similar across these mammalian orders that diverged about 95 million years ago, and therefore appear to be ...

The human cerebral cortex is neither one nor many: Neuronal distribution reveals two quantitatively different zones in the grey matter, three in the white matter, and explains local variations in cortical folding

Frontiers in Neuroanatomy, 2013
The human prefrontal cortex has been considered different in several aspects and relatively enlarged compared to the rest of the cortical areas. Here we determine whether the white and gray matter of the prefrontal portion of the human cerebral cortex ...

Different scaling of white matter volume, cortical connectivity, and gyrification across rodent and primate brains

Frontiers in Neuroanatomy, 2013
Expansion of the cortical grey matter in evolution has been accompanied by an even faster expansion of the subcortical white matter volume and by folding of the grey matter surface, events traditionally considered to occur homogeneously across mammalian ...

Brain scaling in mammalian evolution as a consequence of concerted and mosaic changes in numbers of neurons and average neuronal cell size

Frontiers in Neuroanatomy, 2014
Enough species have now been subject to systematic quantitative analysis of the relationship between the morphology and cellular composition of their brain that patterns begin to emerge and shed light on the evolutionary path that led to mammalian brain ...
