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 ...

Effect of aquatic exercise versus standard care on paraspinal and gluteal muscles morphology in individuals with chronic low back pain: a randomized controlled trial protocol

Author(s): Rosenstein B; Montpetit C; Vaillancourt N; Dover G; Khalini-Mahani N; Weiss C; Papula LA; Melek A; Fortin M; ...

Background: Low back pain (LBP) is one of the most disabling diseases and a major health issue. Despite the evidence of a link between paraspinal and gluteal muscle dysfunction and LBP, it is unkno ...

PILLAR: ParaspInaL muscLe segmentAtion pRoject - a comprehensive online resource to guide manual segmentation of paraspinal muscles from magnetic resonance imaging

Author(s): Anstruther M; Rossini B; Zhang T; Liang T; Xiao Y; Fortin M;

Background: There is an increasing interest in assessing paraspinal morphology and composition in relation to low back pain (LBP). However, variations in methods and segmentation protocols contribute to the inconsistent findings in the literature. We presen ...

At-home computerized executive-function training to improve cognition and mobility in normal-hearing adults and older hearing aid users: a multi-centre, single-blinded randomized controlled trial

Author(s): Downey R; Gagné N; Mohanathas N; Campos JL; Pichora-Fuller KM; Bherer L; Lussier M; Phillips NA; Wittich W; St-Onge N; Gagné JP; Li K; ...

Background: Hearing loss predicts cognitive decline and falls risk. It has been argued that degraded hearing makes listening effortful, causing competition for higher-level cognitive resources need ...

Lactate's behavioral switch in the brain: an in-silico model

Author(s): Soltanzadeh M; Blanchard S; Soucy JP; Benali H;

It is well known that glucose serves as the main energy substrate for the brain, and emerging evidence emphasizes its involvement in both physiological processes and disease (traumatic brain injury, memory, epilepsy, etc.). Furthermore, the usefulness of ma ...

Cervical muscle morphometry and composition demonstrate prognostic value in degenerative cervical myelopathy outcomes

Author(s): Neda Naghdi, James M Elliott, Michael H Weber, Michael G Fehlings, Maryse Fortin

Objectives: This study aimed to examine whether preoperative cervical muscle size, composition, and asymmetry from magnetic resonance imaging (MRI) can predict post-operative outcomes in patients with degenerative cervical myelopathy (DCM).
Methods: A t ...

The effects of acute exercise and a nap on heart rate variability and memory in young sedentary adults

Author(s): Mograss M; Frimpong E; Vilcourt F; Chouchou F; Zvionow T; Dang-Vu TT;

Recent evidence suggests that the autonomic nervous system can contribute to memory consolidation during sleep. Whether fluctuations in cardiac autonomic activity during sleep following physical exercise contribute to the process of memory consolidation has ...
