A Cortical Shape-Adaptive Approach to Local Gyrification Index [PDF]

Medical Image Analysis, 2018
The amount of cortical folding, or gyrification, is typically measured within local cortical regions covered by an equidistant geodesic or nearest neighborhood-ring kernel.

Decreased cortical gyrification in patients with bipolar disorder

Psychological Medicine, 2020
AbstractBackgroundAn aberrant neural connectivity has been known to be associated with bipolar disorder (BD). Local gyrification may reflect the early neural development of cortical connectivity and has been studied as a possible endophenotype of psychiatric disorders. This study aimed to investigate differences in the local gyrification index (LGI) in

Decreased cortical gyrification in major depressive disorder

Psychological Medicine, 2023
AbstractBackgroundEarly neurodevelopmental deviations, such as abnormal cortical folding patterns, are candidate biomarkers of major depressive disorder (MDD). We aimed to investigate the association of MDD with the local gyrification index (LGI) in each cortical region at the whole-brain level, and the association of the LGI with clinical ...

The human pattern of gyrification in the cerebral cortex

Anatomy and Embryology, 1988
The degree of cortical folding found in adult human brains has been analyzed using a gyrification index (GI). This parameter permits the description of a mean value for the whole brain, but also a local specific analysis of different brain regions.

Cortical complexity and gyrification patterns in Parkinson’s disease

NeuroReport, 2020
This study aimed to investigate the cortical complexity and gyrification patterns in Parkinson’s disease (PD) using local fractional dimension (LFD) and local gyrification index (LGI), respectively. In a cross-sectional study, LFD and LGI in 60 PD patients without dementia and 56 healthy controls (HC) were investigated using brain structural MRI data ...

GYRIFICATION IN TWINS DISCORDANT FOR SCHIZOPHRENIA

Schizophrenia Research, 2010
Background:Measures of cortical folding have increasingly been used to assess morphological properties previously not measured in highresolution MRI scans. Assumed to be under genetic influence and relatively stable over the (adult) life-span, the local gyrification index can be measured in 3D across the entire cortical surface. Here we present initial

Increased temporal lobe gyrification in preterm children

Neuropsychologia, 2006
Preterm birth often results in significant learning disability, and previous magnetic resonance imaging (MRI) studies of preterm children have demonstrated reduction in overall cortical tissue with particular vulnerability in the temporal lobe. We measured cortical gyrification in 73 preterm and 33 term control children at 8 years of age and correlated

Order‐specific quantitative patterns of cortical gyrification

European Journal of Neuroscience, 2007
AbstractWhy the extent of cortical gyrification varies across mammals of different brain sizes is a problem that is not clearly understood. The aim of the present study was to test a hypothesis indicating that the order is a significant phylogenetic grouping in terms of quantifiable gyrification indices (GIs) and thus variation between mammals.

Development of human gyrification

2008
Early prenatal brain development is characterized by a lissencephalic smooth cortical surface followed by a rapid development of gyrification during last trimester. Currently there is no agreement in the literature what developmental mechanisms contribute most to the process of gyrification.

POSTNATAL DEVELOPMENT OF THE CEREBRAL GYRIFICATION IN THE CANINE BRAIN

Veterinary Radiology & Ultrasound, 2012
Data herein provide a reference for the normal development of canine postnatal cerebral cortical morphology. The growth of the canine cerebrum involves the emergence of sulci in a regular sequence of appearance through a number of breeds. The sequential course of sulcus development is constant in all breeds of the same age.
