This study examines how unilateral handgrip fatigue at different intensities affects bimanual movement quality, finding no measurable impact on movement quality despite changes in neural dynamics.

This study shows that reticulospinal tract activity scales with handgrip force in humans, unlike contralateral motor cortex.

This study finds that females show smaller brain activation volumes and lower inter-subject variability during motor tasks compared to males, using fMRI data.

This study compares data-driven and theory-based biomarkers for predicting chronic motor outcomes after stroke, finding data-driven models perform better, especially when using structural disconnection measures.

This study examines if high intensity aerobic exercise with motor training improves cognitive-motor function and functional connectivity in chronic stroke patients, finding improved processing speed and reduced connectivity.

This study examines how high-force handgrip contractions of the less-affected limb affect brain activation in stroke participants and controls, finding increased ipsilesional activation in both groups.

This study shows that repeated unilateral handgrip contractions at 50% MVC improve contralateral hand response times and alter functional connectivity and neurochemical levels in sensorimotor areas.
