Summary
Connectivity-based neurofeedback using EEG coherence effectively upregulates positive emotion and enhances brain connectivity. This novel approach shows superior results compared to traditional methods for emotion regulation and mental health treatment.
Area of Science:
- Neuroscience
- Psychology
- Biomedical Engineering
Background:
- Emotion regulation is crucial for well-being.
- Neurofeedback offers non-invasive brain training for mental health.
- Previous methods often relied on single-region activity (fMRI) or EEG power.
Purpose of the Study:
- To investigate connectivity-based EEG neurofeedback for emotion regulation.
- To compare its efficacy against traditional activity-based neurofeedback.
- To explore its potential for treating mental disorders.
Main Methods:
- Utilized connectivity-based EEG neurofeedback focusing on electrode coherence.
- Employed simultaneous fMRI to monitor brain activity.
- Recalled positive autobiographical memories during training.
- Compared results with activity-based and sham neurofeedback.
Main Results:
- Connectivity-based neurofeedback improved BOLD signal and connectivity in emotion-related regions (amygdala, thalamus, insula).
- Observed increased EEG frontal asymmetry and channel coherence.
- Participants showed enhanced positive and reduced negative emotions compared to controls.
Conclusions:
- Connectivity-based neurofeedback is a potentially superior method for emotion regulation.
- It may serve as an effective alternative therapy for mental disorders like PTSD, anxiety, and depression.
- This technique offers individuals greater control over their brain and mental functions.
