Hippocampal atrophy in neurofunctional subfields in insomnia individuals

Frontiers in Neurology, 2022
ObjectiveThe aim of this study was to investigate the pattern of volume changes in neurofunctional hippocampal subfields in patients with insomnia and their associations with risk of development of insomnia.MethodsA total of 120 patients with insomnia ...

Wavelet Features for Recognition of First Episode of Schizophrenia from MRI Brain Images [PDF]

, 2014
Machine learning methods are increasingly used in various fields of medicine, contributing to early diagnosis and better quality of care. These outputs are particularly desirable in case of neuropsychiatric disorders, such as schizophrenia, due to the ...

Individual differences in human path integration abilities correlate with gray matter volume in retrosplenial cortex, hippocampus, and medial prefrontal cortex [PDF]

, 2017
Humans differ in their individual navigational abilities. These individual differences may exist in part because successful navigation relies on several disparate abilities, which rely on different brain structures.

Syndrome‐specific and familial imaging traits in juvenile absence epilepsy

Epilepsia, EarlyView.
Abstract Objective Juvenile absence epilepsy (JAE) is an idiopathic generalized epilepsy characterized by absences, generalized tonic–clonic seizures, and cognitive difficulties. In contrast to juvenile myoclonic epilepsy (JME), where distinct functional and structural brain alterations are well established, it remains unclear whether comparable ...

Statistical Parametric Mapping and Voxel-Based Specific Regional Analysis System for Alzheimer’s Disease (VSRAD): Principles and Clinical Applications

Brain Sciences
Background: The voxel-based specific regional analysis system for Alzheimer’s disease (VSRAD) allows quantitative evaluation of the degree of an individual’s brain atrophy through statistical comparison of brain magnetic resonance imaging (MRI) of their ...

Neural Correlates of Congenital Amusia

Pediatric Neurology Briefs, 2006
Magnetic resonance T1-weighted images were analyzed, using voxel-based morphometry (VBM), to detect brain anatomical differences in two independent groups of adults with congenital amusia (or tone-deafness) compared to controls with normal pitch ...

Cerebral grey matter density is associated with neuroreceptor and neurotransporter availability: A combined PET and MRI study

NeuroImage, 2021
Positron emission tomography (PET) can be used for in vivo measurement of specific neuroreceptors and transporters using radioligands, while voxel-based morphometric analysis of magnetic resonance images allows automated estimation of local grey matter ...

Morphometric analyses of the visual pathways in macular degeneration

, 2014
Introduction. Macular degeneration (MD) causes central visual field loss. When field defects occur in both eyes and overlap, parts of the visual pathways are no longer stimulated.

Increasing power for voxel-wise genome-wide association studies : the random field theory, least square kernel machines and fast permutation procedures [PDF]

, 2012
Imaging traits are thought to have more direct links to genetic variation than diagnostic measures based on cognitive or clinical assessments and provide a powerful substrate to examine the influence of genetics on human brains. Although imaging genetics

Deep characterization of refractory epilepsy due to mild malformation of cortical development with oligodendroglial hyperplasia (MOGHE) and insights into the role of invasive monitoring

Epilepsia, EarlyView.
Abstract Objective Epilepsy surgery is an effective treatment option for patients with medically refractory epilepsy due to mild malformation of cortical development with oligodendroglial hyperplasia (MOGHE). The success of surgery depends on the accurate localization of the epileptogenic zone, which can be challenging due to the subtle imaging ...
