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.
