Gray matter thickness
WebOct 8, 2008 · Developmental studies suggest that greater cortical thickness may be due to unmyelinated neuronal fibers that are categorized as gray matter . Greater cortical thickness may thus implicate poor neuronal connectivity that may affect the speed of information processing locally. WebGeneral and specific abilities capture distinguishable, but related, facets of the intelligence construct. Here, we analyze gray matter with three morphometric indices (volume, cortical surface area, and cortical thickness) at three levels of the intelligence hierarchy (tests, first-order factors, and a higher-order general factor, g).

WebMar 22, 2024 · We aim to explore the most prominent and robust cortical thickness (CTh) and gray matter volume (GMV) alterations associated with childhood maltreatment. A systematic search on relevant studies was conducted through September 2024. WebA study of sleepiness and brain morphology should also consider aging as a possible moderator since sleepiness decreases with aging, 21,22 as does the thickness of the cortex. 23 This suggests that a lower gray matter (GM) volume may be associated with less sleepiness across age groups.
