Quiet Rest

DA

Good
9.84Hz
ALPHA PEAKBrain's dominant frequency in the alpha band (8–13 Hz). Higher = faster cognitive processing.
28.8yr
BRAIN AGEEstimated cognitive age from alpha frequency. Lower than chronological age indicates healthy alpha activity.
42th
CENTILEWhere your alpha frequency sits compared to the general population. 50th = average, higher = faster alpha.
1.15dB
SNRSignal-to-noise ratio. Higher values mean cleaner alpha signal relative to background noise.
Signal details — DA
75.8%
AMPLITUDEPercentage of time windows with strong alpha signal.
-0.060Hz
IAF SHIFTChange in alpha frequency compared to reference.
7.2%
POWER SHIFTChange in alpha power relative to baseline.
12.8%
ALPHA WINDOWS% of time windows with alpha activity above threshold.

Spectral Analysis — DA

Spectrogram shows frequency power over time. Power spectrum shows the detected alpha peak at 9.84 Hz.

IB

Good
10.15Hz
ALPHA PEAKBrain's dominant frequency in the alpha band (8–13 Hz). Higher = faster cognitive processing.
23.2yr
BRAIN AGEEstimated cognitive age from alpha frequency. Lower than chronological age indicates healthy alpha activity.
66th
CENTILEWhere your alpha frequency sits compared to the general population. 50th = average, higher = faster alpha.
1.51dB
SNRSignal-to-noise ratio. Higher values mean cleaner alpha signal relative to background noise.
