Slow Cortical Potentials

Slow Cortical Potentials

They can either facilitate or inhibit learning by the brain during such operations. This is achieved via tonic regulation of a cortical region (“cortical sheet”) to either lower (increased negativity; facilitation) or raise (increased positivity; inhibition) its threshold of firing. Increased negativity will render the region more likely to respond and adapt to stimulus events (i.e. learning); increased positivity will reduce the likelihood of such response. There are indications that SCP modulation may rely on the coordinated activity of neuronal and glial cell systems (Fellin et al., 2009). Threshold regulation can be trained via SCP neurofeedback, with electrode placement determined by functional relevance. There are benefits of SCP neurofeedback reported for a number of clinical conditions. The best evidence pertains to attention deficit disorder, epilepsy and migraine (Wyckoff et al, 2011) but there is also promising clinical data in relation to alcohol dependence, bipolar disorder, major depression, autism and dyslexia. This presentation provides a review of this background and work through the procedures of SCP training and its outcomes.

The impact of dopamine depletion on brain functional connectivity: Basis and clinical implications.

In this talk, Richard Silberstein describes research findings examining the effects of dopamine depletion and dopamine agonists on brain functional connectivity. These findings are also discussed in

Mining clinical data for evidence of the efficacy of Neurofeedback.

As practitioners, we may find ourselves ahead of the research in our implicit knowledge and belief in the efficacy of neurofeedback as an intervention option for improved brain-based functioning. There

Self Directed Neuroplasticity

Neuroplasticity ranks as one of the most exciting findings to emerge from the “Decade of the Brain” as it opened doors to a number of emerging interventions for altering brain functions.

LENS: Low Energy Neurofeedback System. How it is incorporated into our clinical practice.

This presentation provides a brief description of the development of LENS and what is involved when treating clients with LENS. This treatment will be compared with more traditional forms of Neurofeedback.

Deriving Neurofeedback training protocols from EEG analysis and symptom presentation.

This presentation reviews the historical development of symptom guided neurofeedback (NFB) and EEG / QEEG based NFB, and their more recent synthesis in clinical practice. In the late 1960s, Professor Barry Sterman founded the field of NFB with his discovery that NFB can control seizure disorders. From that point on, practitioners began using NFB to treat a wide variety of disorders, mostly tracking changes in symptoms to guide NFB. At the same time, university based research continued to correlate EEG patterns with symptoms. With the rise of Quantitative EEG analysis in the 1980s, it was proposed to use deviations from normative data to guide NFB. Both voltage based norms and coherence based norms were developed. Thus two schools of thought developed, and a certain rivalry emerged between the two.
