2020 NeuroImage: Clinical  
Cognitive impairment is a common consequence of stroke, and the rewiring of the surviving brain circuits might contribute to cognitive recovery.  ...  Using an fMRI ROI-ROI approach, we compared the ipsilesional, contralesional and interhemispheric functional connectivity of three resting-state networks involved in cognition - the Default Mode (DMN),  ...  For the cross-sectional study, the cognitively healthy control group did not differ from patients in age, years of education, or sex.  ...

Jocelyn V. Hull, Lisa B. Dokovna, Zachary J. Jacokes, Carinna M. Torgerson, Andrei Irimia, John Darrell Van Horn
2017 Frontiers in Psychiatry  
Further differences in reported results may be attributable to the age and sex of participants included, designs of the resting-state scan, and to the analysis technique used to evaluate the data.  ...  Classifying autism using brain connectivity is complicated by the heterogeneous nature of the condition, allowing for the possibility of widely variable connectivity patterns among individuals with the  ...  Individuals with ASD are found along an entire continuum of cognitive abilities, ranging from profound disability to exceptional intelligence (2) .  ...
