A population-averaged structural connectomic brain atlas dataset from 422 HCP-aging subjects

Author(s): Xiao Y; Gilmore G; Kai J; Lau JC; Peters T; Khan AR;

Population-averaged brain atlases, that are represented in a standard space with anatomical labels, are instrumental tools in neurosurgical planning and the study of neurodegenerative conditions. Traditional brain atlases are primarily derived from anatomical scans and contain limited information regarding the axonal organization of the white matter. With ...

Cerebral blood flow in schizophrenia: A systematic review and meta-analysis of MRI-based studies

Author(s): Percie du Sert O; Unrau J; Gauthier CJ; Chakravarty M; Malla A; Lepage M; Raucher-Chéné D;

Introduction: Schizophrenia-spectrum disorders (SSD) represent one of the leading causes of disability worldwide and are usually underpinned by neurodevelopmental brain abnormalities observed on a structural and functional level. Nuclear medicine imaging studies of cerebral blood ...

Mapping pontocerebellar connectivity with diffusion MRI

Author(s): Rousseau PN; Chakravarty MM; Steele CJ;

The cerebellum's involvement in cognitive, affective and motor functions is mediated by connections to different regions of the cerebral cortex. A distinctive feature of cortico-cerebellar loops that has been demonstrated in the animal work is a topographic organization that is preserved across its corticopontine, pontocerebellar, and cerebello-thalmo ...

UncertaintyFuseNet: Robust uncertainty-aware hierarchical feature fusion model with Ensemble Monte Carlo Dropout for COVID-19 detection

Author(s): Abdar M; Salari S; Qahremani S; Lam HK; Karray F; Hussain S; Khosravi A; Acharya UR; Makarenkov V; Nahavandi S;

The COVID-19 (Coronavirus disease 2019) pandemic has become a major global threat to human health and well-being. Thus, the development of computer-aided detection (CAD) systems that are capable of accurately distinguishing COVID-19 from other diseases using chest computed tomography (CT) and X-r ...

Structural brain network topological alterations in stuttering adults

Author(s): Gracco VL; Sares AG; Koirala N;

Persistent developmental stuttering is a speech disorder that primarily affects normal speech fluency but encompasses a complex set of symptoms ranging from reduced sensorimotor integration to socioemotional challenges. Here, we investigated the whole-brain structural connectome and its topological alterations in adults who stutter. Diffusion-weighted ima ...

White matter correlates of sensorimotor synchronization in persistent developmental stuttering

Author(s): Jossinger S; Sares A; Zislis A; Sury D; Gracco V; Ben-Shachar M;

Introduction: Individuals with persistent developmental stuttering display deficits in aligning motor actions to external cues (i.e., sensorimotor synchronization). Diffusion imaging studies point to stuttering-associated differences in dorsal, not ventral, white matter pathways, and in the cerebellar peduncles. Here, we studied microstructural white matt ...

Human Activity Recognition: A Comparative Study to Assess the Contribution Level of Accelerometer, ECG, and PPG Signals

Author(s): Afzali Arani MS; Costa DE; Shihab E;

Inertial sensors are widely used in the field of human activity recognition (HAR), since this source of information is the most informative time series among non-visual datasets. HAR researchers are actively exploring other approaches and different sources of signals to improve the performance of HAR systems. In this study, we investigate the impact of co ...

Characterizing white matter alterations subject to clinical laterality in drug-naïve de novo Parkinson's disease

Author(s): Xiao Y; Peters TM; Khan AR;

Parkinson's disease (PD) is a progressive neurodegenerative disorder that is characterized by a range of motor and nonmotor symptoms, often with the motor dysfunction initiated unilaterally. Knowledge regarding disease-related alterations in white matter pathways can effectively help improve the understanding of the disease and propose targeted treatm ...

Development and validation of the multidimensional version of the Fear of Self Questionnaire: Corrupted, culpable and malformed feared possible selves in obsessive-compulsive and body-dysmorphic symptoms.

Author(s): Aardema F, Radomsky AS, Moulding R, Wong SF, Bourguignon L, Giraldo-O'Meara M

In recent years, cognitive-behavioural models of OCD have increasingly recognized the potential role of feared possible selves in the development and maintenance of OCD, while simultaneously re-examining factors that have historically been linked to self-perceptions in OCD. The current article describes the development and validation of a multidimensional ...

Comparing perturbation models for evaluating stability of neuroimaging pipelines.

Author(s): Kiar G, de Oliveira Castro P, Rioux P, Petit E, Brown ST, Evans AC, Glatard T

With an increase in awareness regarding a troubling lack of reproducibility in analytical software tools, the degree of validity in scientific derivatives and their downstream results has become unclear. The nature of reproducibility issues may vary across domains, tools, data sets, and computational infrastructures, but numerical instabilities are though ...

A Cross-Sectional Study on the Impact of Arterial Stiffness on the Corpus Callosum, a Key White Matter Tract Implicated in Alzheimer's Disease

Author(s): Badji A; de la Colina AN; Boshkovski T; Sabra D; Karakuzu A; Robitaille-Grou MC; Gros C; Joubert S; Bherer L; Lamarre-Cliche M; Stikov N; Gauthier CJ; Cohen-Adad J; Girouard H;

Background: Vascular risk factors such as arterial stiffness play an important role in the etiology of Alzheimer's disease (AD), presumably due to the emergence of white matter lesions. However, the impact of arterial stiffness to white matter structure involved in the etiology of AD, includ ...
