Guest guest Posted March 23, 2011 Report Share Posted March 23, 2011 Hello listmates, When there seems to be frontal lobe imbalance (higher alpha on right front, more beta and h.b on right frontal cortex), what do you see, the imbalance of T/B ratio , OR absolute values on LH and RH ? What about the prefrontal lobe imbalance? Does it's alpha,beta and h.b also need to be balanced ? Sincerely, Lynn Quote Link to comment Share on other sites More sharing options...
Guest guest Posted March 23, 2011 Report Share Posted March 23, 2011 Alpha should be higher on the right front. High beta should be low period.

Guest guest Posted March 23, 2011 Report Share Posted March 23, 2011 Thanks Foxx and , It helped a lot. , Just want to make sure of your last sentence. Do you mean that you try to have a lower T(4-6) / B(12-15 Hz) ratio on the right frontal cortex than the left frontal cortex because it makes person feel better and level of attention go up? What about Prefrontal cortex imbalance ? Do you also consider the imbalnce of T/B on prefrontal LEFT and RIGHT ?

It depends on various factors such as EEG power of the frequencies you are analysing. I do pay attention to the T/B ratio and on the whole I try to have a lower T in relation to the left side. Now, the T is usually taken to be between 4-8Hz. But, recently I have changed this so that my ratios are done in relation to 4-6/12-15 Hz and 4-6/15-19Hz. I try to keep the ratios at 1.5 or below. This is because as the person feels better and/or his/her level of attention goes up the ratio for the left side goes lower in relation to the right side. I hope this helps you.

Guest guest Posted March 24, 2011 Report Share Posted March 24, 2011 Hi Lynn, Further to your question, the left side is higher then the right side. So if you have a lower ratio on the left side than on the right side (not the other way around as you say below), you are more likely to have the 12-15Hz and the 15-19Hz a bit higher then the right side which is what one tends to find on normal levels of attention and low anxiety. In relation to your second question, the imbalance, as I tend to do bipolar training, so left and right at the same time, the brain just adjust itself and so this problem does not happen. The measure that seems most relevant is to keep the ratios, both left and right side, below 1.5 as the brain does the rest. It is quite smart on this and so I just let it do what it wants :-) In fact I find this process quite fascinating. As the ratios go down the person's mood and cognitive processing go up. Most of them do not notice these changes, but their family or friends do and point out to them.

Guest guest Posted March 27, 2011 Report Share Posted March 27, 2011 Hi To check my understanding: as ratio on right goes below 1.5 12-15 is increasing and as left goes below 1.5 15-19 is increasing. Is that it? and this is for bipolar montages left and right. Mark RE: imbalanceHi Lynn,Your question is not that simple.
