Objective The thalamus and cerebral cortex are connected via topographically organized, reciprocal connections. Previous studies have revealed thalamic abnormalities in schizophrenia; however, it is not known whether thalamocortical networks differentially affected the disorder. To explore this possibility, authors examined functional connectivity intrinsic low-frequency blood-oxygen-level-dependent (BOLD) signal fluctuations between major divisions of using resting-state MRI (fMRI). Method...
Background Processing speed predicts functional outcome and is a potential endophenotype for schizophrenia. Establishing the neural basis of processing impairment may inform treatment etiology Neuroimaging investigations in healthy subjects have linked to brain anatomical connectivity. However, relationship between white matter (WM) integrity schizophrenia unclear. Method Individuals with underwent diffusion tensor imaging (DTI) completed brief neuropsychological assessment that included...
Abstract In a companion paper by Cohen-Adad et al . we introduce the spine generic quantitative MRI protocol that provides valuable metrics for assessing spinal cord macrostructural and microstructural integrity. This was used to acquire single subject dataset across 19 centers multi-subject 42 (for total of 260 participants), spanning three main manufacturers: GE, Philips Siemens. Both datasets are publicly available via git-annex. Data were analysed using Spinal Cord Toolbox produce...
Abstract Clinical research emphasizes the implementation of rigorous and reproducible study designs that rely on between-group matching or controlling for sources biological variation such as subject’s sex age. However, corrections body size (i.e. height weight) are mostly lacking in clinical neuroimaging designs. This investigates importance parameters their relationship with spinal cord (SC) brain magnetic resonance imaging (MRI) metrics. Data were derived from a cosmopolitan population...
Ipsilateral-projecting corticobulbar pathways, originating primarily from secondary motor areas, innervate the proximal and even distal portions, although they branch more extensively at spinal cord. It is currently unclear to what extent these ipsilateral areas subsequent cortical projections may contribute hand function following stroke-induced damage one hemisphere. In present study, we provide both structural functional evidence indicating that individuals increasingly rely on detriment...
The human somatosensory system comprises dissociable paths for discriminative and affective touch, reflected in separate peripheral afferent populations distinct cortical targets. Differences behavioral neural responses to touch may have an important developmental role early social experiences, which are relevant autism spectrum disorder (ASD). Using probabilistic tractography, we compared the structural integrity of white matter pathways young children with ASD their typically developing...
Abstract Processing speed is the most impaired neuropsychological domain in schizophrenia and a robust predictor of functional outcome. Determining specific cognitive operations underlying processing dysfunction identifying their neural correlates may assist developing pro-cognitive interventions. Response selection, process mapping stimuli onto motor responses, with tests contribute to impairment schizophrenia. This study investigated relationship between behavioral measures response index...

Abstract Of the three largest outputs of cerebral cortex, two have been extensively studied and mapped. Topographic maps cortico-thalamic cortico-striatal functional connectivity in humans are well established. However, for third output, to pontine nuclei, which connect cerebrum cerebellum, existence such an organized pattern is unknown. Here, using high-resolution MRI a large sample size, we found topographically between human cortex pons. Our results indicate rostral-caudal topography;...
Purpose Spinal cord gray‐matter imaging is valuable for a number of applications, but remains challenging. The purpose this work was to compare various MRI protocols at 1.5 T, 3 and 7 T visualizing the gray matter. Methods In vivo data cervical spinal were collected from nine different centers. Data processing consisted automatically segmenting its matter co‐registering back‐to‐back scans. We computed SNR using two methods (SNR_single single scan SNR_diff difference between scans) white/gray...

Abstract Recent findings have shown connections of ipsilateral cortico-reticulospinal tract (CRST), predominantly originating from secondary motor areas, to not only proximal but also distal portions the arm. In unilateral stroke, CRST side is intact and thus has been proposed as a possible backup system for post-stroke rehabilitation even hand. We argue that although areas can provide control joints, it insufficient either hand or coordinated shoulder movements due its extensive branching...
