DA

Good
9.89Hz
ALPHA PEAKBrain's dominant frequency in the alpha band (8–13 Hz). Higher = faster cognitive processing.
35.1yr
BRAIN AGEEstimated cognitive age from alpha frequency. Lower than chronological age indicates healthy alpha activity.
37th
CENTILEWhere your alpha frequency sits compared to the general population. 50th = average, higher = faster alpha.
0.71dB
SNRSignal-to-noise ratio. Higher values mean cleaner alpha signal relative to background noise.
Signal details — DA
79.7%
AMPLITUDEPercentage of time windows with strong alpha signal.
-0.411Hz
IAF SHIFTChange in alpha frequency compared to reference.
-20.3%
POWER SHIFTChange in alpha power relative to baseline.
6.4%
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 9.89 Hz.

IB

Good
9.98Hz
ALPHA PEAKBrain's dominant frequency in the alpha band (8–13 Hz). Higher = faster cognitive processing.
33.4yr
BRAIN AGEEstimated cognitive age from alpha frequency. Lower than chronological age indicates healthy alpha activity.
44th
CENTILEWhere your alpha frequency sits compared to the general population. 50th = average, higher = faster alpha.
