Yes, when i noted slowing brain function i was refering to how folks describe the observable clinical symptoms they feel such as lethargy, ADD, feeling mentally 'slow' as thoughts don't seem to connect as rapidly, mentally tasks take longer to complete. I did not clarify this on the post.

I wasn't refering to the data/EEG as being impacted by speed, nor have i ever considered that was even possible...that seems a mute point; though i was not clear in stating this. What i typically see is as you note an increase in CCAC measures (usually a significant increasing pattern across a period of time/sessions, which correlates to increasing symptom complaints during that time, as one would expect). Within Western Michigan i seem to have an abundance of opportunity to capture these connections, as over the years I've been training with NF (67%-80%) of my clients' data increase and decrease in emergent variability during the same correlated seasonal periods (estimated tracking of my cases annually across the last 8 years). Correlating symptoms vary within these clients, yet the data patterns have been relatively consistent in changing towards less organized CCAC data with increased seasonal extrinsic effects; more organized CCAC data as seasonal extrinsics minimize.

Molly,

While I'm sure that respiratory- related issues can serve as extrinsic constraints I wouldn't refer to the their effect as "slow<ing> brain function". It's not the the EEG "slows", although that may (or may not) be apparent in some ways of looking at the data. Rather, it's more that the emergent variability in the EEG is greatly increased and that occurs in a non-averaged, pseudo-random fashion. What appears as "slowing" of the EEG is one of the effects of the increased turbulence and emergent variability, not the inverse.
