The Failure of the Gyrification Index (GI) to Account for Volumetric Reorganization in the Evolution of the Human Brain

Journal of Human Evolution, 1992
The gyrification indices (GI) recently compared for chimpanzee and human brains by Armstrong et al. (1991) ignores important volumetric differences in primary visual striate cortex (area 17 of Brodmann) and the lateral geniculate body which provides the optic radiation to the visual cortex.

Pre-frontal lobe gyrification index in schizophrenia, mental retardation and comorbid groups: An automated study

NeuroImage, 2007
In this paper, we describe the application of an automated method of calculating Gyrification Index (GI) - the Automated GI (A-GI) - to a total of 95 age-matched and sex-matched patients with mental retardation, schizophrenia, comorbid mental retardation and schizophrenia and controls.

Lower Gyrification of the Ventromedial Prefrontal Cortex in Posttraumatic Stress Disorder: An ENIGMA-PTSD Study [PDF]

Biological Psychiatry Global Open Science
Background: Cortical gyrification involves the formation of folds in the cerebral cortex, coinciding with key neurodevelopmental processes. Its strong correlation with increased cortical surface area and decreased cortical thickness may improve cortical ...

Association Between Anterior Hippocampal Gyrification and Episodic Memory Performance in Neurotypical Young Adults. [PDF]

Hippocampus
ABSTRACT The hippocampus is critical for episodic memory. The relationship between its structural variability and individual differences in episodic memory performance among neurotypical young adults, however, remains unclear. Previous studies have not consistently found associations between hippocampal volume and episodic memory or other aspects of ...

S158. URBANICITY INDEX AND CORTICAL GYRIFICATION IN SCHIZOPHRENIA [PDF]

Schizophrenia Bulletin, 2020
Abstract Background Urban birth and upbringing are considered to be risk factors for schizophrenia, but recent studies do not support the same. While several hypotheses are suggested, the pathogenic mechanisms are not known.

Reduced cortical gyrification in the posteromedial cortex in unaffected relatives of schizophrenia patients with high genetic loading

npj Schizophrenia, 2021
Although abnormal cortical gyrification has been consistently reported in patients with schizophrenia, whether gyrification abnormalities reflect a genetic risk for the disorder remains unknown.

Cortical gyrification morphology in PTSD: A neurobiological risk factor for severity?

Neurobiology of Stress, 2021
Post-traumatic stress disorder (PTSD) is a prevalent psychiatric disorder, particularly among military personnel and veterans. Cortical gyrification, as a specific metric derived from structural MRI, is an index of the convoluted folding and patterning ...
