<p>The measure of coherence is the measure of the stability of the phase relationship between different sites in the brain. That is to say, we are measuring connectivity from the perspective of flexibility.&nbsp; Hypercoherence shows a lack of flexibility
    in the connection relationships; firings are locked into the same rhythm. Imagine soldiers goose-stepping or a crowd clapping in unison. Hypercoherence is an “over-connectivity,” or the stability of the phase relationship between the areas of the
    brain are in a locked pattern.</p>
<p>Hypercoherence is problematic in the sense that it can create “tunnel vision” or the inability to switch tasks readily. On the other hand, it may lead to a sort of frenetic distractibility, where nothing gains the complete attention and the individual
    always feels “scattered,” “distracted,” and busied. When attempting to understand what theta hypercoherence would feel like, in comparison to beta hypercoherence, it is best to consider the frequency, itself, as an adjective describing the “stuckness”
    of coherences.</p>
<p>Hypocoherence is a lack of stability, in terms of the brain waves never remaining consistent in their relative relationship to other areas of the brain. A metaphor for hypocoherence is cacophony in a symphony. When we see hypocoherence it indicates a
    failure to synchronize, a lack of stability in the in frequencies. Very often hypocoherence will result in feeling “off,” and an inability to connect things.&nbsp;</p>
