HIRREM in Military Personnel

HIRREM is a closed-loop, allostatic, acoustic stimulation neurotechnology intended to support auto-calibration of neural oscillations. The core technology is commercially available as a technique for relaxation. Scalp sensors monitor brain frequencies and amplitudes, and in real time, software algorithms translate specific frequencies into audible tones of varying pitch. These are reflected via earbuds in as little as 4-8 milliseconds. The in-office intervention for this study is administered as a series of up to twenty four, typically 1.5-2 hours sessions, comprised of 4-10 protocols (some eyes open, some eyes closed), lasting 6-40 minutes each, working at different scalp locations. Sessions are received over 12 days. Two sessions can be done in a half day. The intervention is received while comfortably seated in a zero gravity chair.
