DA

Bad
10.08Hz
ALPHA PEAKBrain's dominant frequency in the alpha band (8–13 Hz). Higher = faster cognitive processing.
31.7yr
BRAIN AGEEstimated cognitive age from alpha frequency. Lower than chronological age indicates healthy alpha activity.
51th
CENTILEWhere your alpha frequency sits compared to the general population. 50th = average, higher = faster alpha.
0.07dB
SNRSignal-to-noise ratio. Higher values mean cleaner alpha signal relative to background noise.
Signal details — DA
59.7%
AMPLITUDEPercentage of time windows with strong alpha signal.
0.108Hz
IAF SHIFTChange in alpha frequency compared to reference.
-22.3%
POWER SHIFTChange in alpha power relative to baseline.
4.5%
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 10.08 Hz.

IB

Bad
9.78Hz
ALPHA PEAKBrain's dominant frequency in the alpha band (8–13 Hz). Higher = faster cognitive processing.
37.1yr
BRAIN AGEEstimated cognitive age from alpha frequency. Lower than chronological age indicates healthy alpha activity.
30th
CENTILEWhere your alpha frequency sits compared to the general population. 50th = average, higher = faster alpha.
2.14dB
SNRSignal-to-noise ratio. Higher values mean cleaner alpha signal relative to background noise.
