What EEG frequencies are typically trained? What do the frequencies mean?
• Beta frequencies (13-20 Hz) tend to be associated with an alert, awake, attentive state • Alpha-theta training (rewarding 8-11 or 8-12 Hz for alpha and 4-8 Hz for theta) guides people to deep quiet states • Excessive theta and delta (slow wave activity) can be associated with distractibility, inattentiveness or not focusing. • Excessive high beta is associated with anxiety, tension. It can interfere with attention.
