Brain differences in early- and late- blind subjects mapped using tensor-based morphometry

چکیده
INTRODUCTION: The central nervous system is remarkably adaptive to environmental demands. In blind subjects, in particular, the brain is functionally reorganized in the absence of visual input. However, few studies have examined anatomical correlates of blindness. Here we present fully 3D maps of brain anatomical differences in earlyand late-blind subjects versus sighted subjects, detected using tensor-based morphometry. We hypothesized that nonvisual structures would be expanded in the blind, with a greater relative expansion in those who were blind from an early age of onset.

Brain structure changes visualized in early- and late-onset blind subjects
We examined 3D patterns of volume differences in the brain associated with blindness, in subjects grouped according to early and late onset. Using tensor-based morphometry, we mapped volume reductions and gains in 16 early-onset (EB) and 16 late-onset (LB) blind adults (onset <5 and >14 years old, respectively) relative to 16 matched sighted controls. Each subject's structural MRI was fluidly r...
متن کاملAge of onset of blindness affects brain anatomical networks constructed using diffusion tensor tractography.
Studying blindness with various onset ages may elucidate the ways that unimodal sensory deprivation at different periods of development shape the human brain. In order to determine the effect of the onset age on brain anatomical networks, we extended a previous study of 17 early blind (EB) subjects with an additional 97 subjects with various onset ages. We constructed binary anatomical networks...
متن کاملP 24: Evaluation of the Voxel Based Morphometry in Quantitative Analysis of Brain MRI Images
Introduction: Voxel based morphometry is a type of statistical parametric mapping that can be used to investigate the effect of diseases such as epilepsy, Alzheimer's disease and Parkinson's disease or other agent such as skills on brain structure (white matter, gray matter and cerebrospinal fluid). The aim of this study is evaluate the effectiveness of this method in detection of differen...
متن کاملWhither the hippocampus? FDG-PET hippocampal hypometabolism in Alzheimer disease revisited.
BACKGROUND AND PURPOSE The hippocampus is a widely recognized area of early change in AD, yet voxelwise analyses of FDG-PET activity differences between AD and CN controls have consistently failed to identify hippocampal hypometabolism. In this article, we propose a high-dimensional PET-specific analysis framework to determine whether important hippocampal metabolic FDG-PET activity differences...
متن کامل3D pattern of brain abnormalities in Williams syndrome visualized using tensor-based morphometry.
UNLABELLED Williams syndrome (WS) is a neurodevelopmental disorder associated with deletion of approximately 20 contiguous genes in chromosome band 7q11.23. Individuals with WS exhibit mild to moderate mental retardation, but are relatively more proficient in specific language and musical abilities. We used tensor-based morphometry (TBM) to visualize the complex pattern of gray/white matter red...
