Neurofeedback training

The loop in plain terms

1. Sense — EEG sensors on the scalp read moment-to-moment activity.
2. Compute — software extracts features (e.g., amplitude in selected bands, ratios, stability, relations between sites) several times per second.
3. Compare — those features are checked against a target range chosen for the training goal.
4. Respond — the screen changes: movement toward the target produces a clearer, steadier image; movement away eases that response.
5. Adapt — thresholds adjust gradually so feedback stays responsive as your signal shifts.

What’s being trained

• Targets come from baseline readings and the objective of the session (e.g., quieting excessive fast activity at a site, improving stability in a band, or smoothing coordination between regions).
• Feedback is contingent: only changes in the desired direction are followed by the consistent “better” screen state.

Why change happens

Brains are adaptive systems. When a state is followed by a consistent positive contingency, it recurs more often. The loop delivers that contingency hundreds of times per session, biasing networks toward states that meet the rule. With practice, those states become easier to enter and maintain; baseline activity shifts in the trained direction.

Your role

Sit, watch, and let the contingency run. The adjustment is largely implicit—repetition, not efforting, does the work.
