Significance
For: researcher
The problem
Most global qEEG normative databases lack regional Middle Eastern population baselines for clinical and neurotech calibration.
Method
19-channel 10-20 standardized recordings from 420 healthy Arab participants (ages 18-65) across eyes-open and eyes-closed conditions.
Result
Documented reproducible posterior alpha peak frequency distributions and established regional z-score spectral boundaries.
Why it matters
Provides the first open reference standard for Arab neurotechnology calibration and clinical EEG neurofeedback.
Limitations
Resting-state only; does not cover active cognitive or motor-imagery task paradigms.
