Contralesional motor cortex activation depends on ipsilesional corticospinal tract integrity in well-recovered subcortical stroke patients.
BACKGROUND The relationship between structural and functional integrity of descending motor pathways can predict the potential for motor recovery after stroke. The authors examine the relationship between brain imaging biomarkers within contralesional and ipsilesional hemispheres and hand function in well-recovered patients after subcortical stroke at the level of the internal capsule. OBJECT...
متن کاملStructural damage and functional reorganization in ipsilesional m1 in well-recovered patients with subcortical stroke.
BACKGROUND AND PURPOSE Both structural atrophy and functional reorganization of the primary motor cortex (M1) have been reported in patients with subcortical infarctions affecting the motor pathway. However, the relationship between structural impairment and functional reorganization in M1 remains unclear. METHODS Twenty-six patients exhibiting significant recovery after subcortical infarctio...
متن کاملEnhanced Effective Connectivity Between Primary Motor Cortex and Intraparietal Sulcus in Well-Recovered Stroke Patients.
BACKGROUND AND PURPOSE Ischemic strokes with motor deficits lead to widespread changes in neural activity and interregional coupling between primary and secondary motor areas. Compared with frontal circuits, the knowledge is still limited to what extent parietal cortices and their interactions with frontal motor areas undergo plastic changes and might contribute to residual motor functioning af...
متن کاملCorrection to: Enhanced Effective Connectivity Between Primary Motor Cortex and Intraparietal Sulcus in Well-Recovered Stroke Patients.
In the article by Schulz et al, “Enhanced Effective Connectivity Between Primary Motor Cortex and Intraparietal Sulcus in Well-Recovered Stroke Patients,” which published online on January 7, 2016, and appeared in the February 2016 issue of the journal (Stroke. 2016;47:482–489. DOI: 10.1161/STROKEAHA.115.011641), a correction was needed. The second paragraph of the Results section, titled “Task...
متن کاملCortical connectivity after subcortical stroke assessed with functional magnetic resonance imaging.
OBJECTIVE This study aimed at identifying the impact of subcortical stroke on the interaction of cortical motor areas within and across hemispheres during the generation of voluntary hand movements. METHODS Twelve subacute stroke patients with a subcortical ischemic lesion and 12 age-matched control subjects were scanned using 3-Tesla functional magnetic resonance imaging. Subjects performed ...
