- Protocol
- 19-channel live z-score (PZOK) training plus sLORETA high-beta inhibition at one Brodmann area
- Sessions
- 1 to 2 sessions of 20-30 min
- Equipment
- BrainMaster BrainAvatar
Key findings
- Three adults with chronic anxiety and social difficulty, each with excess high beta in one Brodmann area
- Training combined 19-channel PZOK with sLORETA inhibition of high beta at that area
- Targeted high beta fell from about 3 to about 2 standard deviations after 1 to 2 sessions
- Clients reported less social fear; one rated it falling from 9.5 to 2 out of 10
Three brief case reports from two clinicians who added sLORETA training of one brain region to 19-channel live z-score (PZOK) training for clients with long-standing anxiety. In each case the QEEG showed excess high beta in one Brodmann area linked to the client's complaints (area 20 in one case, area 23 in two), and that activity was trained down while the whole-head z-score training ran. After one or two sessions of 20 to 30 minutes, the targeted high beta fell by roughly one standard deviation, and each client described feeling calmer and easier in social situations. The authors present this as an encouraging early sign; there was no control condition and the follow-up was short.
