Adaptation of motor control strategies and physiological arousal during repeated blocks of split-belt walking

This study investigates how physiological arousal and motor control strategies adapt during repeated split-belt walking, finding reduced arousal and adaptation in later blocks.

CALM-VLM: CALIBRATION AND SELECTIVE PREDICTION IN VISION-LANGUAGE MODELS FOR RELIABLE BRAIN MRI CLASSIFICATION

CALM-VLM improves confidence and reliability in brain MRI classification by calibrating vision-language models and enabling selective prediction.

Females versus males exhibit greater brain activation in sensorimotor regions during motor imagery after stroke

This study finds sex differences in brain activation during motor imagery after stroke, with females showing greater sensorimotor activation and males greater cerebellar and parietal activation.

Movement quality moderates the effect of spatially congruent cues on the stability of rhythmic bimanual finger movements.

This study investigates how spatially congruent cues affect the stability of asymmetric rhythmic bimanual movements, finding that their benefits depend on movement frequency and strategy.

Interhemispheric inhibition between dorsal premotor and primary motor cortices is released during preparation of unimanual but not bimanual movements.

Females exhibit smaller volumes of brain activation and lower inter-subject variability during motor tasks

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

Data-driven biomarkers outperform theory-based biomarkers in predicting stroke motor outcomes

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.

Improved cognitive-motor processing speed and decreased functional connectivity after high intensity aerobic exercise in individuals with chronic stroke

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.

Chronic stroke sensorimotor impairment is related to smaller hippocampal volumes: An ENIGMA analysis

This study finds that smaller ipsilesional hippocampal volume is associated with worse upper limb sensorimotor impairment in chronic stroke patients, with a stronger effect in women.

Global brain health modulates the impact of lesion damage on post-stroke sensorimotor outcomes

This study shows that global brain health, measured by brain age, influences post-stroke sensorimotor outcomes and mediates the effect of lesion damage.

Experience-dependent learning and myelin plasticity in individuals with stroke

This study examines how skilled motor practice affects myelin plasticity in stroke patients using multi-component relaxation imaging, finding increased myelin water fraction in specific brain regions after training.

Smaller spared subcortical nuclei are associated with worse post-stroke sensorimotor outcomes in 28 cohorts worldwide

This study finds that smaller spared subcortical nuclei are linked to worse sensorimotor outcomes after stroke, varying by time since stroke and type of impairment.

Multiple bouts of high-intensity interval exercise reverse age-related functional connectivity disruptions without affecting motor learning in older adults

Exercise improves resting state functional connectivity in older adults without enhancing motor learning.

Behavioral and neural evidence of the rewarding value of exercise behaviors: A systematic review

This review examines automatic reactions to exercise and sedentary behaviors, finding physical activity as a reward but limited evidence for sedentary behaviors as a reward.
