Protocole

SN

Good
10.32Hz
ALPHA PEAKBrain's dominant frequency in the alpha band (8–13 Hz). Higher = faster cognitive processing.
29.3yr
BRAIN AGEEstimated cognitive age from alpha frequency. Lower than chronological age indicates healthy alpha activity.
69th
CENTILEWhere your alpha frequency sits compared to the general population. 50th = average, higher = faster alpha.
1.26dB
SNRSignal-to-noise ratio. Higher values mean cleaner alpha signal relative to background noise.
Signal details — SN
85.6%
AMPLITUDEPercentage of time windows with strong alpha signal.
0.849Hz
IAF SHIFTChange in alpha frequency compared to reference.
15.0%
POWER SHIFTChange in alpha power relative to baseline.
5.3%
ALPHA WINDOWS% of time windows with alpha activity above threshold.

Spectral Analysis — SN

Spectrogram shows frequency power over time. Power spectrum shows the detected alpha peak at 10.32 Hz.

CI

Good
10.12Hz
ALPHA PEAKBrain's dominant frequency in the alpha band (8–13 Hz). Higher = faster cognitive processing.
33.0yr
BRAIN AGEEstimated cognitive age from alpha frequency. Lower than chronological age indicates healthy alpha activity.
54th
CENTILEWhere your alpha frequency sits compared to the general population. 50th = average, higher = faster alpha.
1.24dB
SNRSignal-to-noise ratio. Higher values mean cleaner alpha signal relative to background noise.
