- Аннотация: Despite the increasing popularity of neurofeedback, its mechanisms of action arestill poorly understood. This study aims to describe the processes underlyingimplicit electroencephalographic neurofeedback. Fifty-two healthy volunteers wererandomly assigned to a single session of infra-low frequency neurofeedback or shamneurofeedback, with electrodes over the right middle temporal gyrus and the right inferiorparietal lobule. They observed a moving rocket, the speed of which was modulatedby the waveform derived from a band-limited infra-low frequency filter. Immediatelybefore and after the session, the participants underwent a resting-state fMRI. Networkbasedstatistical analysis was applied, comparing post- vs. pre-session and real vs.sham neurofeedback conditions. As a result, two phenomena were observed. First, wedescribed a brain circuit related to the implicit neurofeedback process itself, consistingof the lateral occipital cortex, right dorsolateral prefrontal cortex, left orbitofrontalcortex, right ventral striatum, and bilateral dorsal striatum. Second, we found increasedconnectivity between key regions of the salience, language, and visual networks, whichis indicative of integration in sensory processing. Thus, it appears that a single session ofimplicit infra-low frequency electroencephalographic neurofeedback leads to significantchanges in intrinsic brain connectivity.
