Subthreshold Alpha (SUB/ALPHA)

Subthreshold 10-Hz Sound Suppresses EEG Theta

The purpose of this article is to present the details of a newly developed home treatment protocol that provides immediate enhancement of attention and also markedly shortens the frequency and duration of office-based neurofeedback treatment of ADD/ADHD. The critical component of the treatment is the self-administration of a blend of tones embedded in filtered white noise (SUB/ALPHA) that immediately suppresses EEG theta with resultant immediate enhancement of attentional focus. Data from four studies indicating the suppressive effect of SUB/ALPHA on clinical and nonclinical populations are presented.
