Repeated functional magnetic resonance imaging (fMRI) studies aim to detect changes in brain activity over time, e.g. to analyze the cerebral correlates of therapeutic interventions. This approach requires a high test-retest reliability of the measures used to rule out incidental findings. However, reliability studies, especially for cognitive tasks, are still difficult to find in the literature. In this study, 10 healthy adult subjects were scanned in two sessions, 16 weeks apart, while… CONTINUE READING
