Connectivity Changes Underlying Neurofeedback Training of Visual Cortex Activity

摘要: Neurofeedback based on real-time functional magnetic resonance imaging (fMRI) is a new approach that allows training of voluntary control over regionally specific brain activity. However, the neural basis successful neurofeedback learning remains poorly understood. Here, we assessed changes in effective connectivity associated with visual cortex Using dynamic causal modeling (DCM), found participants to increase activity was increased between and superior parietal lobe. Specifically, who learned their showed top-down lobe cortex, at same time reduced bottom-up processing. These results are consistent efficient employment attention imagery, which were cognitive strategies used by
