White matter fMRI: Exploring functional differentiation in the corpus callosum
Introduction White matter fMRI is a controversial idea. To date, the majority of fMRI studies have focused on gray matter, largely for two reasons: 1) cerebral blood flow/volume is reduced in white matter relative to gray matter (e.g., [1, 2]); and 2) post-synaptic potentials are thought to be the primary source of the signal measured in fMRI (e.g., [3]). Despite this, a growing number of studi...
متن کاملFunctional Topography of Human Corpus Callosum: An fMRI Mapping Study
The concept of a topographical map of the corpus callosum (CC) has emerged from human lesion studies and from electrophysiological and anatomical tracing investigations in other mammals. Over the last few years a rising number of researchers have been reporting functional magnetic resonance imaging (fMRI) activation in white matter, particularly the CC. In this study the scope for describing CC...
متن کاملOrganising white matter in a brain without corpus callosum fibres.
Isolated corpus callosum dysgenesis (CCD) is a congenital malformation which occurs during early development of the brain. In this study, we aimed to identify and describe its consequences beyond the lack of callosal fibres, on the morphology, microstructure and asymmetries of the main white matter bundles with diffusion imaging and fibre tractography. Seven children aged between 9 and 13 years...
