Guest guest Posted May 27, 2008 Report Share Posted May 27, 2008 I'm aware that before-after behavioral changes can occur with neurofeedback in the absence of changes being seen in EEG measures, but how often do EEG changes occur following neurofeedback without there also being behavioral changes?

Guest guest Posted May 28, 2008 Report Share Posted May 28, 2008 , 12.3% of the time. (kidding). Chances are very good that something changes in the EEG most of the time that you train. The question is whether we are measuring the thing that changed (when there were results and we see " no change " in the EEG) or whether we were training the thing that needed to change (when there is a change in the EEG and the problem continues). Unless you did full pre/post QEEG's with eyes closed and open and at task, and did both at relatively comparable times, something might have changed in a phase relationship between two sites or in an ability to shift into and stay in higher activation states at task as a result of our training, but that might not show up--might not even be measured--in our pre/post testing. And if you trained, for example, to reduce central theta/beta ratios in a client who has excessive temporal lobe high-beta, then you might be able to see the change in the ratio, but you wouldn't actually be impacting on the EEG issue that is standing in the way of the client being able to pay attention at work, etc. Pete I'm aware that before-after behavioral changes can occur with neurofeedback in the absence of changes being seen in EEG measures, but how often do EEG changes occur following neurofeedback without there also being behavioral changes? ..-- Van Deusenpvdtlc@...http://www.brain-trainer.com 305/433-3160The Learning Curve, Inc.
