Case 5 (TBI)
Significant incremental improvement of working memory followed the initial course of HEG
treatments. He became able to read again and his depression was somewhat improved.-

F8 targeted sessions were begun in November '03 following the first presentation of this report at the ISNR meeting. A dual HEG headband initially monitored Fp2 while training Fp1. After 22 sessions the dual HEG array was changed to monitor F8 while activating the AFz position.
-
During the first Afz training session a significant 3-minute 30% rise at F8 was recorded. At the end of the 10-minute segment, asked to describe the significant rise "I felt like crying" was his response.-
Thus was confirmed the use of the F8 position for treatment of Eisenberger's 'emotion regulator'. Subsequent HEG sessions targeted this position. During the third HEG F8 targeted session he suddenly stopped the session with the recognition: "I feel like I used to. My brain is working again!"-

Conclusion:
Pre-frontal treatment with HEG may have great utility in treating anxiety. Anxiety can be associated with both "high beta' and "high alpha' states.-
HEG training at the lateral prefrontal locations on the hypothesized pathways resulted, after 12 to 30 sessions, in significant symptom improvement in four samples of 9 similar cases.-
These results support Targeted Location theory and the role of the amygdale in anxiety/panic Further support is provided that the targeted pathway to the amygdale can be influenced with pre-frontal HEG training.-
This is a preliminary test that opens a possible pathway for analysis and training of florid emotional (anxiety, PTSD, anger, and TBI) cases toward more controlled responses. Although the hypothesized results happened according to prediction, so much is still unknown about brain responses to stimuli that these results must be approached with caution. The interconnectivity of neural populations is so large that almost any brain area can be expected to make a contribution to path length and effective time of action.
