Re: Low Theta Amps in Parietals

[Guest guest]

Gretchen,

I think it's safe to say that if the alpha/theta ratio is already 2+, you probably don't need to train up alpha. If you have more beta in back than in the front, the first question to ask is whether the problem is low beta in front (less than 14% with EC) or high beta in back (above 14% with EC). If the beta is low in front, then training a windowed squash left-frontally (maybe Fz/A1 and F3/A1 or F3/A1 and C3/A1) with a window of 12-18 Hz might be good. If the beta is high in the back, then training a windowed squash in the right-rear quadrant (

e.g. P4/A2 and Oz/A2) with a window at 8-14 Hz might be good.

Greetings...I seem to remember something about not training alpha up in back, if its amplitudes are 2-times (or more) greater than the theta amplitudes back there. True?So, what's the best way to deal with a front/back beta reversal in this case? Had thought about a windowed squash, but if theta is already low... Perhaps with coherence or synchrony?THANKS in advance!-Gretchen -- Van Deusen

Pete,

I have a similar question about a client that I saw last week for a first

assessment.

A/T at EO and Task is in the red zone on all sites, due to general lack

of blocking.

There are slight reversals L/R (especially alpha) and F/B.

But Beta is high on all sites as well (around 18% at frontals and even

19-21% at posterior sites).

The client suffers from social withdrawal and sensory hypersensitivity.

All kinds of sensory input irritate her.

She always 'feels' her head (inside).

Should I inhibit (right-hemisferical, F and P) beta?

Or is excess of alpha the problem?

The histograms show excess of 8-10 Hz and above 15 Hz, generally at all

sites.

SMR at C4 is 9%

Jan,

One thing you have to watch for when alpha blocking appears to be failing (alpha/theta ratio doesn't drop 30-50% from EC to EO or task), is the peak alpha frequency. If you look at the Histograms page, you may well see that there is an " alpha shape " (bars much higher eyes closed and dropping eyes open) stronger--as you mentioned--at 8-10 Hz than at 10-12. Often you will also see this shape at 6-8 Hz as well. Since the A/T ratio divides the amplitudes of 8-12 Hz activity by the amplitudes of 4-8 Hz activity, if the " theta " is actually acting like alpha, then the ratio doesn't change much when eyes are opened. The problem is not failure in alpha blocking. It's excessively slow alpha.

I'd probably start in the right rear quadrant (P4/A2 and Oz/A2) and do an eyes-closed windowed squash, leaving 10-14 Hz in the window. That could help speed up alpha AND help reduce beta back there.

THANKS, Pete...and you read my mind about what to do about the beta, which, is high (16%) in front and higher in back. Shall try the squaaaaaaash. Best, Gretchen
