  • Magnetoencephalography Discriminates Modality-Specific Infraslow Signals Less Than 0.1 Hz (abs.)
    Leistner S, Sander T, Wuebbeler G, Link A, Elster C, Curio G, Trahms Lutz, Mackert Bruno-Marcel

    DC-magnetoencephalography (DC-MEG) technique has been refined and allows to record cortical activity in the infraslow frequency range less than 0.1 Hz noninvasively. Important questions however, remained, especially, how specific these infraslow activations can be recorded and whether different activations, for example, motor versus acoustic, can be separated.

  • Neurofeedback at Infra-low Frequencies of the EEG
    by Othmer S

    It is time for an update on our collective experience with infra-low frequency neurofeedback training. One impetus is the continuing confusion in the rest of the field about the implications of this kind of training, both theoretically and practically. Some are still skeptical of the whole enterprise. Others are coming to terms with it, but would prefer to regard it as filling certain niches within the panoply of neurofeedback approaches. Such pigeon-holing would nicely leave unperturbed whatever has come before in terms of neurofeedback approaches and understandings. While it is probably true that no single neurofeedback technique will cover all the bases, the infra-low training gives every sign of being broadly applicable to the concerns that surface in neurofeedback offices. It's not just for PTSD and for the autism spectrum. It follows, then, that it must be folded into our thinking generally about neurofeedback and cannot be compartmentalized.

  • The Ongoing Saga of Infra-low Frequency Training
    by Othmer S

    Our infra-low frequency training is sending ripples through the field of neurofeedback because it appears to represent such a fundamental departure from prevailing models. It is at such a bifurcation point that a professional community is tested in its assumptions, in its procedures, in its processes for finding accommodation, and indeed in its humanity. Unfortunately, the field of neurofeedback already has a history of fragmentation behind it. Therefore history does not augur for a benign accommodation to our new findings. More than likely we will just be in for continuing Balkanization of our field.

  • Infra-low Frequency Neurofeedback Training
    by Othmer S

    The recent newsletter on Infra-low Frequency Training raised a number of issues within our readership and within the larger neurofeedback community. The principal issues are addressed in the following.

    First of all there is the issue of how we detect infra-low frequency activity with an amplifier that "cuts off" at 0.08 Hz. The Cygnet system incorporates a single stage of high-pass filtering into its design. We did so to provide more stable and more graceful operation of the system in its most common applications. Little did we know that down the line our most common applications would extend well into the frequency range that we were cutting off with our filter.

  • Northeast Regional Biofeedback Society Fall Conference
    by Othmer S

    The program of the Northeast Regional Biofeedback Society Fall Conference, convening on the grounds of the former Women's adjunct college of Rutgers University in New Brunswick, NJ, quite possibly pointed the way to our near-term future, namely the mutual accommodation of the biofeedback and neurofeedback perspectives. The one-day conference was preceded by an all-day seminar on Heart Rate Variability (HRV) training, conducted by Paul Lehrer, Bronya and Evgeny Vaschillo, and Maria Karavidas.

  • Infra-Low Frequency Neurofeedback
    by Othmer S

    Over the last several years we have increasingly explored the low-frequency domain of the EEG for neurofeedback applications. Surprisingly to us all this has led us to the realm of infra-low frequency training, below the 0.5 Hz cutoff that is commonplace in EEG work. It is tempting to refer to this very low frequency neurofeedback as a breakthrough, but in fact this has simply been the latest iteration of a long progression from one milestone to the next in an evolution of our particular protocol-based approach. So it does not feel like a breakthrough to those who have been involved every step of the way. It only appears like a breakthrough because when considered on its own it seems like a complete negation of the standard assumptions of neurofeedback. Perhaps in consequence of that the method has already attracted the usual gallery of skeptics. The survival of this kind of skepticism at this late date reminds us that the typical understanding people have about neurofeedback is being grossly violated. A reappraisal of the usual assumptions is therefore in order.

  • Introduction to Infra-low Frequency Training
    by Othmer S

    The first convincing evidence for EEG feedback efficacy in the management of pathophysiology was with regard to generalized seizures. The early work by Sterman, Lubar, as well as the subsequent follow-up by others, therefore remains a crucial point of reference for the various feedback techniques that have built upon the early protocol of SMR reinforcement combined the theta-band and high-beta band inhibition. Remarkably, the essential features of the early approach have been retained in the various evolutionary pathways that have emanated from the early work. This essential similarity has perhaps obscured other aspects of the training approach that have changed substantially over time, the significance of which may not have been fully appreciated except in reflection. In this newsletter we consider some of these changes and their implications generally, as well as for seizure management in particular.
