Neurofeedback is an emerging non-pharmacological approach for improvement of emotional and bodily regulation. In a pilot study, we evaluated the dynamics of emotional regulation and interoception after infra-low frequency EEG neurofeedback from the T4P4 site, which we have previously shown to influence the brain intrinsic connectivity underlying multisensory integration. Nine females with prenosological signs of emotional dysregulation, including anxiety, mild depression and somatoform symptoms, underwent 15 sessions of infra-low frequency neurofeedback. The examination, including fMRI-based heartbeat detection task, Screening for Somatoform Symptoms, Autonomic Perception Scale, Mayer-Salovey-Caruso Emotional Intelligence Test, Spielberger State-Trait Anxiety Inventory, Short Health Anxiety Inventory and Toronto Alexithymia Scale, was performed at inclusion, after a waiting period and after a course of neurofeedback. First, we found that the interoceptive accuracy, interoception-related brain activation and emotional intelligence remained stable — no effects of neurofeedback were detected. We suggest that these trait abilities are not influenced by this particular type of neurofeedback. Second, a significant beneficial shift in the parameters characterizing subjective well-being, including anxiety, alexithymia and somatoform symptoms, was observed after the neurofeedback but not after the waiting period. Further research is necessary to differentiate the nonspecific psychotherapeutic and neurophysiological effects of the intervention.
