Summary
Alpha/theta (A/T) neurofeedback training significantly enhances mentalization and Default Mode Network (DMN) connectivity in a non-clinical sample. This study explored the neurobiological underpinnings of A/T training, suggesting its potential for improving mentalization skills.
Area of Science:
- Neuroscience
- Psychology
Background:
- Alpha/theta (A/T) neurofeedback shows potential in psychiatric treatment.
- The precise psychological and neurobiological mechanisms of A/T effectiveness remain unclear.
Purpose of the Study:
- To investigate the efficacy of A/T neurofeedback in boosting mentalization in a non-clinical population.
- To examine alterations in electroencephalographic (EEG) functional connectivity within the Default Mode Network (DMN) following A/T training.
Main Methods:
- Forty-four participants were randomly assigned to either an A/T neurofeedback group (NFG, n=22) or a waiting list control group (WLG, n=22).
- Both groups completed the mentalization questionnaire (MZQ) and Symptom Checklist-90-Revised (SCL-90-R) pre- and post-intervention.
- EEG functional connectivity within the DMN was assessed.
Main Results:
- The NFG demonstrated a statistically significant increase in total MZQ scores compared to the WLG (p=0.007).
- A/T training was associated with enhanced EEG functional connectivity in key DMN regions, including the Posterior Cingulate Cortex.
Conclusions:
- A/T neurofeedback training is effective in enhancing mentalization capabilities.
- The findings support A/T training's role in modulating DMN connectivity, offering insights into its therapeutic potential.
