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 ...

Localized astrogenesis regulates gyrification of the cerebral cortex

Science Advances, 2022
The development and evolution of mammalian higher cognition are represented by gyrification of the laminar cerebral cortex and astrocyte development, but their mechanisms and interrelationships remain unknown. Here, we show that localized astrogenesis plays an important role in gyri formation in the gyrencephalic cerebral cortex.

PI3K-Yap activity drives cortical gyrification and hydrocephalus in mice

eLife, 2019
Mechanisms driving the initiation of brain folding are incompletely understood. We have previously characterized mouse models recapitulating human PIK3CA-related brain overgrowth, epilepsy, dysplastic gyrification and hydrocephalus (Roy et al., 2015 ...

Cortical Gyrification Morphology in Adult Males with Mild Traumatic Brain Injury

Neurotrauma Reports, 2022
Cortical gyrification, as a specific measure derived from magnetic resonance imaging, remains understudied in mild traumatic brain injury (mTBI). Local gyrification index (lGI) and mean curvature are related measures indexing the patterned folding of the

Increased brain gyrification and subsequent relapse in patients with first-episode schizophrenia

Frontiers in Psychiatry, 2022
Most schizophrenia patients experience psychotic relapses, which may compromise long-term outcome. However, it is difficult to objectively assess the actual risk of relapse for each patient as the biological changes underlying relapse remain unknown. The

Small-world properties of brain morphological characteristics in Anorexia Nervosa.

PLoS ONE, 2019
Cortical thickness and gyrification abnormalities in anorexia nervosa (AN) have been recently described, but no attempt has been made to explore their organizational patterns to characterize the neurobiology of the disorder in the different stages of its

Cortical thickness, gyrification and sulcal depth in trigeminal neuralgia

Scientific Reports, 2021
Neuroimaging studies have documented brain structural alterations induced by chronic pain, particularly in gray matter volume. However, the effects of trigeminal neuralgia (TN), a severe paroxysmal pain disorder, on cortical morphology are not yet known.

Longitudinal Changes in Brain Gyrification in Schizophrenia Spectrum Disorders

Frontiers in Aging Neuroscience, 2021
Previous magnetic resonance imaging (MRI) studies reported increased brain gyrification in schizophrenia and schizotypal disorder, a prototypic disorder within the schizophrenia spectrum. This may reflect deviations in early neurodevelopment; however, it

Abnormal cortical gyrification in criminal psychopathy

NeuroImage: Clinical, 2018
Psychopathy is a personality disorder characterized by interpersonal and emotional abnormalities (e.g., lack of empathy and guilt) and antisocial behavior. Psychopathy has been associated with a number of structural brain abnormalities, most notably in orbital frontal and anterior/medial temporal regions, that may underlie psychopathic individuals ...

Illustration of gyrification analysis.

, 2013
(A) The mean gyrification estimate over all subjects is displayed on the averaged normalized probe-set. Conclusively, channels (#4 and #11) over the interhemispheric sulcus as well as channel #2, which probably covers parts of the middle frontal gyrus ...
