Differential patterns of cortical expansion in fetal and preterm brain development

Abstract The human cerebral cortex undergoes a complex developmental process during gestation, characterised by rapid cortical expansion and gyrification. This study investigates in vivo cortical growth trajectories using longitudinal MRI data from fetal and preterm cohorts.

Cross-species cortical alignment identifies different types of anatomical reorganization in the primate temporal lobe

eLife, 2020
Evolutionary adaptations of temporo-parietal cortex are considered to be a critical specialization of the human brain. Cortical adaptations, however, can affect different aspects of brain architecture, including local expansion of the cortical sheet or ...

Developmental overproduction of cortical superficial neurons impairs adult auditory cortical processing [PDF]

, 2022
While evolutionary cortical expansion is thought to underlie the evolution of human cognitive capabilities, excessive developmental expansion can lead to megalencephaly, often found in neurodevelopmental disorders.

Generation of cortical neurons through large-scale expanding neuroepithelial stem cell from human pluripotent stem cells

Stem Cell Research & Therapy, 2020
Background Considerable progress has been made in converting human pluripotent stem cells (hPSCs) into cortical neurons for disease modeling and regenerative medicine. However, these procedures are hard to provide sufficient cells for their applications.

Time-Coherent Expansion of MEG/EEG Cortical Sources

NeuroImage, 2002
In this study we estimated the spatial extent of cortical areas of time-coherent activity using the inverse problem in magneto/electroencephalography (MEEG). The model discussed here uses classical regularization tools in order to force the inverse solution to be piecewise coherent. First, the cortex was seeded by focal dipolar sources.

Src kinases regulate de novo actin polymerization during exocytosis in neuroendocrine chromaffin cells. [PDF]

PLoS ONE, 2014
The cortical actin network is dynamically rearranged during secretory processes. Nevertheless, it is unclear how de novo actin polymerization and the disruption of the preexisting actin network control transmitter release.

Conical expansion of the outer subventricular zone and the role of neocortical folding in evolution and development

Frontiers in Human Neuroscience, 2013
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 species, cortical volume does not keep pace with cortical surface area,

Mapping Region-Specific Longitudinal Cortical Surface Expansion from Birth to 2 Years of Age [PDF]

, 2013
The human cerebral cortex develops rapidly and dynamically in the first 2 years of life. It has been shown that cortical surface expansion from term infant to adult is highly nonuniform in a cross-sectional study.

The learning-relative hemodynamic modulation of cortical plasticity induced by a force-control motor training

Frontiers in Neuroscience, 2022
BackgroundNovel motor skills are generally acquired through repetitive practices which are believed to be strongly related to neural plasticity mechanisms.
