Guest guest Posted December 6, 2008 Report Share Posted December 6, 2008 Hello Pete Please excuse this question – it is not exactly main-stream NFB, although I am sure, should be of interest to many. I have no practical, hands-on NFB experience and my time is mainly consumed by hardware development as you know. I have, however, followed this group’s postings religiously for at least a year. From this I have learned that typical NFB protocols should be applied over a period of 20 sessions and that some treatments such as those for ADD/ADHD require at least 50 sessions. Yet, changes can sometimes be seen after a single training session. I have also learned that NFB does not always result in the good, as wished for, results. In fact, a wrong training protocol can have serious consequences. The recent postings by ‘JW’ here and on the biofeedback group being an example. There has been a lot of talk about BCI (Brain Computer Interface) technology for gaming and for the purposes of “control” for things such as a wheelchair, computer mouse, etc. There is a lot of confusion in the media regarding this technology. Specially, there is confusion between EEG enabled control and EMG/EOG enabled control. The much reported demo of the Audeo (Texas Instruments) “a neckband that translates thought into speech” for instance, is a device that makes use of EMG only and has nothing to do with EEG. Emotiv EPOC also just released a statement announcing that they have delayed the launch of their BCI gaming product “due to issues of it actually working”. If a true EEG-based BCI is used for purposes of control, it results in the “loop being closed”. Although the application is for purposes of control, it can result in (unintentional) neurofeedback, can it not? The use of said technology could thus have good and bad NFB side effects, depending on the “client’s” mental (QEEG) state? It could even be possible for a positive NFB response to turn negative due to excessive, repetitive “training” resulting in over-training? Are there sites and/or protocols that can be regarded as safe for purposes of control and that do not have any NFB consequences? I have never seen any articles/discussion of this subject.
