Peak Frequency

Peak frequency is a statistic that tells us what the frequency within a band was that had the highest amplitude.  For example, in the alpha band (8-12 Hz), 10 Hz should be highest in most adults.  Values rising above that may result in problems experienced by the client, depending on where we see this, and peaks below 10 can often result in cognitive difficulties, word-finding problems, etc.  The TQ8 shows you peaks in alpha, beta and the overall peak.  Looking at the three together, once you understand more about the EEG and the assessment, you can tell a lot about a brain.

The great majority of the brains I’ve seen over the years don’t stay in one state or frequency for long periods.  One great benefit of the brain lies in its very ability to shift states on a dime depending on what task lies before it, but that seems to disappoint and irritate you.
