Brain rhythms
Alpha, Beta, Theta, SMR - normalized powers of brain rhythms from 0 to 1.
Peak frequencies
Alpha Peak, Beta Peak, Theta Peak - instantaneous peak frequencies within each range.
Alpha profile
IAF, IAPF, IAPF Power, IABW, IAPF Suppression - personal neurophysiological passport.
Cognitive metrics
Attention, Relaxation, Cognitive Load, Cognitive Control are high-level composite indicators.
Derived indices
Relaxation Index, Concentration Index, Fatigue Score, Reverse Fatigue, Accumulated Fatigue, Productivity Score, Alpha Gravity.
Cardiovascular (PPG)
HR, RR(M), Mo, SDNN, CV, AMo, MxdMn, SI Baevsky, SAT Kaplan, Perfusion.
Final statuses
Stress, Recommendation, State - final binary and text statuses.
Technical Metrics
IsConnected, Battery, Serial, Firmware, Mode, Session, Data Markup, Impedance, Artifacts, etc.
Hierarchy of data trust
When analyzing Neiry data, follow this procedure:
Level 1 - absolute priority (check first)
Valid State, Artifacts, Perfusion, PPG quality, Average µV, electrode impedance. If there are problems here, the remaining data is not interpreted.
Level 2 - high reliability
SDNN, SI, Alpha Peak vs IAPF, Accumulated Fatigue. These metrics are well researched and reliable with clean data.
Level 3 - medium reliability
Concentration, Relaxation, Fatigue Score. Requires correct calibration for accuracy.
Level 4 - dynamic
Instant Frequency Peaks, Emotions. Significant only when sustained for 2+ minutes. Short-term jumps are noise, not a signal.
