Guest guest Posted December 9, 2002 Report Share Posted December 9, 2002 Rob, From what I have read and heard at trainings, the 6.5-7.5 hz range is important to several cognitive tasks and there are some potential shortcomings to training it down. Marvin Sams talks about this a great deal, a paper of his is in the archives at www.snr-jnt.org. It is quite long but has a lot of good information in it.

Guest guest Posted December 9, 2002 Report Share Posted December 9, 2002 Thanks, , I thought my memory hadn't abandoned me. I thought with all this talk about squash protocols things may have changed. So if one is doing a squash protocol does that mean you `notch-out' the 7Hz range? I went to the sight you listed and did a search on Marvin Sams, but didn't see the article you mention. Do you know the name of it?

Guest guest Posted December 9, 2002 Report Share Posted December 9, 2002 Although 7 Hz (called frontal midline theta or FMT) does seem to be related to memory function and recall, the issue with training it down would be more of a concern at Fz, Afz or FCz. If you are training at the 3 or 4 sites over the left or right hemispheres, it should not make much difference. I do use 8Hz as a high end of theta in the assessment, and I do usually train lower frequencies (2.5-6.5 as you mentioned) when I am working with a client, but that is largely to pick up the slow theta and high delta.

Guest guest Posted December 9, 2002 Report Share Posted December 9, 2002 I believe the paper in question by Marvin Sams is: Mathematically Derived Frequency Correlates in Cerebral Function: Theoretical and Clinical Implications for Neurofeedback Training (whew!) It ain't as stuffy as it sounds. It's a good read. Find it at: http://www.greatbrain.com/mathematics.html HH Re: Inhibit the 7Hz Thanks, , I thought my memory hadn't abandoned me.

Guest guest Posted December 9, 2002 Report Share Posted December 9, 2002 Rob, Some folks squash the whole band, and it does seem to be effective. The squash will, as a general rule, bring down the highest peaks first and results in a " leveling " of the spectrum as seen on the brainmirror. if teh 6-8 hz is not peaking the chances it will be squahsed are low. The things I have read refer to teh activity more in teh central frontal areas so training at other locations may not be such an issue. I used to do a whole spectrum 3-38hz squash with the BAPro until I got my hands on the BMScope and learned how to use it. I got very good results that way. I occasionally do the same thing now but not as often. The " windowed squash " , as Long called it, notches (windows) off several different frequencies and can be easily modified to suit your needs. I window it a little different depending on the results of assessment. The way it is set up is that it reads from the BMr software delta theta alpha and hibeta. I set delta 2-6, theta 8-12(or 11), alpha 22-32, and hibeta 32-36. That leaves the traditional lobeta and beta frequencies free to do their own thing. Long spent some time with teh script and found that the rations theta/smr on the rightr and theat/beta on the left changed at times more reliabley than with a more traditional approach. I'll try find a reference to the paper for you. At 8:56 PM +0000 12/9/02, robc11374 <ecummings@...> wrote: >Thanks, , I thought my memory hadn't abandoned me.

Guest guest Posted December 10, 2002 Report Share Posted December 10, 2002 Yes, I actually came across this when I was perusing the brainm group. It was given in regard to gama training. It appears that Marvin Sams believes strongly in training 40Hz. Rob > > >Hello Pete, > > > > > >I was looking at you assessments and noticed that you've increased > > >Theta up to 8Hz.

Guest guest Posted December 10, 2002 Report Share Posted December 10, 2002 I find myself wondering if the concern over frontal midline theta in theta reduction protocols is really necessary. As far as I can tell, nobody has so far documented a case of memory impairment following frontal or midline theta down training, although Jay Gunkelman says that he has heard about a few reports of this. Lubar and other very experienced clinicians say that they have never had this problem with theta reduction. Although frontal midline theta supposedly appears intermitantly during tasks requiring active mental work or with episodic recall, Lubar states that has observed frontal midline theta, but generally during math calculations. And, Lubar also states: " However haveing worked with several thousand cases of ADD/HD since the 1970s I do not recall any cases where suppression of 4-8 or 6-10hz at either FZ, CZ, or PZ or sequential FCZ-CPZ has had a negative effect on memory or any other cognitive function. However in our NFB training we use NFB combined with reading, listenin, and by itself but not during calculation, so maybe we did not effect the FMT. " Margaret Ayers, who primarily focuses on reducing theta amplitudes, also has reported to me that she has never observed any memory problems with frontal inhibition of 4-7 Hz theta. Neidermeyer reports that whereas others have reported about frontal midline theta, he has been unable to produce it in his own subjects. My understanding of his discussion of this issue is that he wonders if frontal midline theta might actually be related to mild fatigue or boredom...in other words, some mental drifting away from the task. Hope these thoughts are useful......... Fred Re: Inhibit the 7Hz Thanks, , I thought my memory hadn't abandoned me. I thought with all this talk about squash protocols things may have changed.

Guest guest Posted December 10, 2002 Report Share Posted December 10, 2002 Hi all, I read about this idea a few weeks ago after ordering a back issue of J_SNR. (Vol4, #2). In Clinical Corner there is a discussion of 40 Hz. band activity and possible link to pre-attentive binding. That got me thinking that it might be useful for a learning tool, or to improve memorization. I am actually looking for data regarding memory and learning, as I have to help my son learn a lot of stuff for school. Heck, even this old dog, too! Look up the back issue if you get a chance. It too is worth the read. Thank you for the link.
