PSK Non-Linear Data Analysis And 21 Hz Augmentation Training

The question of the appropriate mathematical tools for analyzing real-time EEG has recently become more complex and chaotic - and that is the good news. As Non-Linear Dynamical Time-Series analysis has gained more precision and acceptance, it has demonstrated interesting trends in EEG patterns as an effect of Neurofeedback - trends which could not be seen through older, linear techniques.
Even though Non-Linear Dynamical Analysis may seem more difficult, abstruse or challenging - especially to the mathematically challenged among us - clinical decision making becomes straight forward and easy. Simply being able to conceptualize a system as Non-linear has one particularly important implication for Neurofeedback: Non-linear dynamical systems can be influenced or controlled through the use of four distinct procedures, regardless of the specific organization, parameters or effects of the particular system being controlled. The implications of this for Neurofeedback are profound.
Using Non-linear dynamical control procedures, simple interventions can lead to profound shifts, and these shifts can be understood functionally, with no particular need for neuroanatomical localization. The recent ascendancy of wide band suppression paradigms at various sites represent one such case, as does the utility of a new augment target: viz. 21 Hz center frequency.
In this presentation, non-linear dynamical techniques will be used to demonstrate the increased and systematic spectral effects of the 21 Hz center augment, within a quasi wide band suppression paradigm. This direct application of Non-Linear Dynamical Control Procedures has been called the Period 3 Approach, and has broad application across the range of clinical disorders with which Neurofeedback is used. Moreover, the principles underlying this approach can be used with any kind of equipment. Thus, a seemingly complex tool (viz. NLD mathematics), can lead to a simple clinical approach for practitioners that works across the entire range of disorders that respond to Neurofeedback.
