Evidentiary Basis for Infra-Low Frequency Neurofeedback
by Siegfried Othmer, Chief Scientist, The EEG Institute
Abstract -  Infra-Low Frequency Neurofeedback impinges on brain-based dysfunctions quite comprehensively, but the resulting improvements in self-regulatory competence cannot typically be captured both quantitatively and unambiguously. A measurable functional challenge is called for, and the Continuous Performance Test (CPT) offers such a challenge, one that both tests critical neuro-regulatory functions and has the benefit of broad acceptance within the neuropsychological community. A concise appraisal of results from a large database, one that extends over more than a decade and over thousands of clinical offices, is offered here as supportive testimony to the clinical effectiveness and practical utility of ILF neurofeedback in application to a wide variety of clinical conditions.

The Role of the Continuous Performance Test
by Siegfried Othmer
The test challenges the person under both high-demand and low-demand conditions. Under high-load conditions, the testee is more likely to make errors of commission, whereas under low-load conditions, the testee is more likely to make errors of omission. In addition to counting errors of omission and commission, the test determines the average reaction time, as well as the standard deviation of reaction time, the variability. ...
