Voxel-based morphometry in Alzheimer’s disease
Expert Review of Neurotherapeutics, 2008Recent morphometric MRI studies have investigated brain volume abnormalities associated with the diagnosis of Alzheimer's disease (AD) using voxel-based morphometry (VBM). This technique allows the assessment of gray matter volumes in subjects with AD or related conditions compared with healthy controls in an automated fashion, across the whole brain ...

Voxel-based morphometry in narcolepsy
Sleep Medicine, 2005Voxel-based morphometry (VBM) is a magnetic resonance imaging (MRI)-based indirect volumetry, which allows the investigation of the entire brain without restriction of predefined regions-of-interest. Recent studies using this technique reported controversial results in patients with narcolepsy.In this study, 12 patients with narcolepsy according to the

Cerebellar voxel-based morphometry in essential tremor
Journal of Neurology, 2022Imaging studies investigating cerebellar gray matter (GM) in essential tremor (ET) showed conflicting results. Moreover, no large study explored the cerebellum in ET patients with resting tremor (rET), a syndrome showing enhanced blink reflex recovery cycle (BRrc).To investigate cerebellar GM in ET and rET patients using voxel-based morphometry (VBM ...

At its simplest, voxel-based morphometry (VBM) involves a voxelwise comparison of regional gray matter ‘density’ between two groups of subjects. Density here refers to the relative amount of gray matter and should not be confused with cell packing density (number of cells per unit volume of neuropil).

Voxel-based morphometry of disgust proneness
Neuroscience Letters, 2012This voxel-based morphometry study investigated whether the personality trait disgust proneness is associated with gray matter volume (GMV) of distinct brain regions implicated in disgust processing. We analyzed brain structural data from 99 healthy women, who had rated their tendency to experience disgust for different disgust domains (offensive food,

Voxel-Based Morphometry in Frontotemporal Dementia
Human Physiology, 2020Frontotemporal dementia (FTD) is a clinically, genetically and pathologically heterogenous neurodegenerative disorder. FTD is characterized by a focal atrophy, which makes it a promising candidate for study using voxel-based morphometry (VBM). Visual assessment of magnetic resonance imaging of the brain is subjective and often depends on the researcher’

Schizophrenia with auditory hallucinations: A voxel-based morphometry study
Progress in Neuro-Psychopharmacology and Biological Psychiatry, 2008Many studies have shown widespread but subtle pathological changes in gray matter in patients with schizophrenia. Some of these studies have related specific alterations to the genesis of auditory hallucinations, particularly in the left superior temporal gyrus, but none has analysed the relationship between morphometric data and a specific scale for ...

The neural substrates of procrastination: A voxel-based morphometry study
Brain and Cognition, 2018Procrastination is a pervasive phenomenon across different cultures and brings about lots of serious consequences, including performance, subjective well-being, and even public policy. However, little is known about the neural substrates of procrastination.
