Re: Swingles Theta/Beta ratio at O1 [1 Attachment]

Hi Pete

I am still in some confusion. Does this mean T4,T6 and P4 would be higher than O1 in alpha amplitude?

Thanks for the pic.

Re: Swingles Theta/Beta ratio at O1 [1 Attachment]

Mark,Mark,The right-rear quadrant would take in T4, T6, P4 and O2, and I would expect that it would be the highest alpha and 6-8 Hz theta on the head. However, the point O1 is generally higher than O2.I'm attaching an image that demonstrates what I mean.Pete-- Van Deusenpvdtlcgmailhttp://www.brain-trainer.comUSA 305 433 3160BR 47 3346 6235The Learning Curve, Inc.

Could you expand on your statement below?

O1 should be the highest alpha site on the head. Moving forward from there, alpha switches to the right and should be higher over the right hemisphere everywhere else. That's one reason Alpha Theta training is often done at O1/A1.I thought the back right quadrant should have the highest alpha.
