MVComp toolbox: MultiVariate Comparisons of brain MRI features accounting for common information across metrics

Author(s): Tremblay SA; Alasmar Z; Pirhadi A; Carbonell F; Iturria-Medina Y; Gauthier CJ; Steele CJ;

Multivariate approaches have recently gained in popularity to address the physiological unspecificity of neuroimaging metrics and to better characterize the complexity of biological processes underlying behavior. However, commonly used approaches are biased ...

Decreased long-range temporal correlations in the resting-state functional magentic resonance imaging blood-oxygen-level-dependent signal reflect motor sequence learning up to 2 weeks following training

Author(s): Jäger AP; Bailey A; Huntenburg JM; Tardif CL; Villringer A; Gauthier CJ; Nikulin V; Bazin PL; Steele CJ; ...

Decreased long-range temporal correlations (LRTC) in brain signals can be used to measure cognitive effort during task execution. Here, we examined how learning a motor sequence affects long-range ...

The impact of lesion side on bilateral upper limb coordination after stroke

Author(s): Shih PC; Steele CJ; Hoepfel D; Muffel T; Villringer A; Sehm B;

Background: A stroke frequently results in impaired performance of activities of daily life. Many of these are highly dependent on effective coordination between the two arms. In the context of bimanual movements, cyclic rhythmical bilateral arm coordinatio ...

Modeling venous bias in resting state functional MRI metrics

Author(s): Huck J; Jäger AT; Schneider U; Grahl S; Fan AP; Tardif C; Villringer A; Bazin PL; Steele CJ; Gauthier CJ; ...

Resting-state (rs) functional magnetic resonance imaging (fMRI) is used to detect low-frequency fluctuations in the blood oxygen-level dependent (BOLD) signal across brain regions. Correlations bet ...

Using cortico-cerebellar structural patterns to classify early- and late-trained musicians

Author(s): Shenker JJ; Steele CJ; Zatorre RJ; Penhune VB;

A body of current evidence suggests that there is a sensitive period for musical training: people who begin training before the age of seven show better performance on tests of musical skill, and also show differences in brain structure-especially in motor ...

Visuo-motor transformations in the intraparietal sulcus mediate the acquisition of endovascular medical skill

Author(s): Paul KI; Mueller K; Rousseau PN; Glathe A; Taatgen NA; Cnossen F; Lanzer P; Villringer A; Steele CJ; ...

Performing endovascular medical interventions safely and efficiently requires a diverse set of skills that need to be practised in dedicated training sessions. Here, we used multimodal magnetic res ...

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 topogra ...

Predicting future cognitive decline from non-brain and multimodal brain imaging data in healthy and pathological aging

Author(s): Hebling Vieira B; Liem F; Dadi K; Engemann DA; Gramfort A; Bellec P; Craddock RC; Damoiseaux JS; Steele CJ; Yarkoni T; Langer N; Margulies D ...

Previous literature has focused on predicting a diagnostic label from structural brain imaging. Since subtle changes in the brain precede a cognitive decline in healthy and pathological aging, our ...

Mental rotation ability predicts the acquisition of basic endovascular skills

Author(s): Paul KI; Glathe A; Taatgen NA; Steele CJ; Villringer A; Lanzer P; Cnossen F;

Due to the increasing complexity of diseases in the aging population and rapid progress in catheter-based technology, the demands on operators' skills in conducting endovascular interventions (EI) has increased dramatically, putting more emphasis on tra ...

Motor sequences; separating the sequence from the motor. A longitudinal rsfMRI study

Author(s): Jäger AP; Huntenburg JM; Tremblay SA; Schneider U; Grahl S; Huck J; Tardif CL; Villringer A; Gauthier CJ; Bazin PL; Steele CJ; ...

In motor learning, sequence specificity, i.e. the learning of specific sequential associations, has predominantly been studied using task-based fMRI paradigms. However, offline changes in resting s ...

Early musical training shapes cortico-cerebellar structural covariation

Author(s): Shenker JJ; Steele CJ; Chakravarty MM; Zatorre RJ; Penhune VB;

Adult abilities in complex cognitive domains such as music appear to depend critically on the age at which training or experience begins, and relevant experience has greater long-term effects during periods of peak maturational change. Previous work has sho ...
