swLORETA neurofeedback (standardized weighted Low Resolution Electromagnetic Tomography) is a type of advanced brain training technique that uses real-time EEG data to help individuals self-regulate their brain activity. It’s a step up from traditional neurofeedback because it doesn’t just work with surface-level EEG signals — it digs deeper. swLORETA is a source localization method, meaning it estimates where in the brain electrical activity is coming from. EEG normally picks up electrical signals from the scalp, but swLORETA uses mathematical modeling to reconstruct 3D images of brain activity deep within the cortex. In neurofeedback, this allows for:
- Targeting specific brain regions (like the anterior cingulate, insula, amygdala, etc.)
- Training based on neural networks or regions, rather than just frequency bands at the scalp.
How swLORETA Neurofeedback Works
- EEG Recording: A high-density EEG cap (often 19+ channels) records brainwave activity in real time.
- Source Localization: swLORETA calculates where in the brain the signals are originating.
- Feedback Loop: The system compares your brain activity to an optimal pattern (either normative or individualized).
Reinforcement: Through visual or auditory feedback, your brain is gently guided to shift toward the desired state.
