Frontal lobe language laterality comparison between fMRI task activation and connectivity (original) (raw)

This study compares language lateralization patterns in the frontal lobe using functional MRI (fMRI) during a word generation task and resting state connectivity. Results showed greater left hemisphere dominance during the task (average lateralization index of +0.529) compared to a more bilateral connectivity during rest (average lateralization index of +0.039). These findings suggest a discord between task-induced activation and resting state connectivity, highlighting the potential for further exploration of language-related task paradigms and their influence on brain connectivity.
