Subperiosteal Expansion and Cortical Remodeling of the Human Femur and Tibia with Aging
Science, 1982Increases with aging in subperiosteal dimensions and second moments of area (measures of bending and torsional rigidity) in femoral and tibial cross sections are documented in an archeological sample from the American Southwest. Significant differences between cross-sectional sites and between sexes in the pattern of cortical remodeling with age are ...

Cerebral Cortical Gray Expansion Associated With Two Second-Generation Antipsychotics
Biological Psychiatry, 2005Second-generation antipsychotics (SGAs) differ from first-generation antipsychotics (FGAs) with respect to induction of less extrapyramidal morbidity, partially reducing negative symptoms, and causing modest improvement in neurocognitive functioning in patients with schizophrenia. SGAs demonstrate 5-HT2a antagonism.

Cortical progenitor expansion, self-renewal and neurogenesis—a polarized perspective
Current Opinion in Neurobiology, 2011Neural stem and progenitor cells giving rise to neurons in developing mammalian neocortex fall into two principal classes with regard to location of mitosis-apical and basal, and into three principal classes in terms of cell polarity during mitosis-bipolar, monopolar, and nonpolar.

Mechanisms of subventricular zone expansion after focal cortical ischemic injury
Journal of Comparative Neurology, 2005AbstractThe rodent subventricular zone (SVZ) contains neural precursor cells that divide and then die in place or migrate to the olfactory bulb through the rostral migratory stream (RMS) to become new neurons. Despite the normally tight control in cell numbers in this region in adults, previous work from our laboratory and others has shown that SVZ ...

Roles of functional strain and capsule compression on mandibular cyst expansion and cortication
Archives of Oral Biology, 2019Cyst expansion in bone involves bone resorption but is often accompanied by adjacent bone formation with cortication. The mechanisms for these two apparently opposite processes remain unclear. From a mechanobiological perspective, functional strain drives bone remodeling, which involves both bone apposition and resorption. In this study, we explore the

Modeling Fetal Cortical Expansion Using Graph-Regularized Gompertz Models
2016Understanding patterns of brain development before birth is of both high clinical and scientific interest. However, despite advances in reconstruction methods, the challenging setting of in-utero imaging renders precise, point-wise measurements of the rapidly changing fetal brain morphology difficult.

In addition to the lateral left and right hemispheric divisions of the brain, the neocortex can also be divided along an anterior and posterior gradient. The posterior regions, or the occipital, parietal, and temporal lobes, can be thought of as elegant sensory processors.
