“…The five criterion sessions had a mean 4.4 days since the previous session, compared to 8.2 for the remaining sessions (previously seen in Frederick, 2012). A similar effect was not seen for the control task.…”

“…Arnstein, D., Cui, F., Keysers, C., Maurits, N. M., & Gazzola, V. (2011 It is commonly argued that the mechanism of action of biofeedback involves increasing awareness of subjective correlates of one's physiological state (Frederick, 2007(Frederick, , 2012. However, the relationship between awareness and control of physiological states is largely unexplored.…”

This keynote will discuss some of the wellestablished and direct affects of trauma on developing brains and specific brain functions responsible for attention, concentration, regulating emotions, and engaging in satisfying relationships. Dr. Kolk and colleagues are currently studying whether neurofeedback can reverse those brain changes. The importance of this pursuit is evident when considering that many traumatized children and adults continue to feel chronically on edge, scared, agitated, collapsed, and helpless, even after exposure to treatment and medications. To deal with this they often try to cope with alcohol or drugs. Medications may make life more manageable but they also affect motivation and curiosity, and rarely really lead to increased focus, relaxation, and engagement. Thus this lecture will review the way trauma impacts brain development and show the effects of neurofeedback. The Neuropsychopathology of Traumatic Brain Injury Mark Gordon, MDOwner and Medical Director of Millennium-TBI, Encino, California, USA In this presentation, Dr. Gordon will walk through some of the science that has helped his team provide treatment to patients where no improvement was thought possible.Some cases will be presented to illustrate the approach to diagnosis and treatment of Traumatic Brain Injury (TBI) for those who have failed to respond to traditional care. He will discuss at length the influence and relevance of neuropsychopharmacology, neuropsychobehavioral characteristics, and neuroplasticity to the diagnosis of TBI. Both genetic and epigenetic influences on neuroplasticity will be described, as will the details of hormonal mechanisms regulating reactive emotions from the limbic system, which influence intelligence and emotional presence. Additionally, the creation, importance, and delicate balance of neurosteroids with regard to behavioral reactions and mental wellbeing will be explained. Mindful Creativity Sayyed Mohsen Fatemi, PhDAssociate, Department of Psychology, Harvard University, Massachusetts, USA This talk will explicate how Langerian mindfulness opens up a new horizon for exploring the novel possibility in the world of mind and body. In view of a distinction between meditation-based mindfulness and Langerian mindfulness, the talk will elucidate how Langerian mindfulness would give rise to developing new avenues of creativity with implications for health and well-being. In line with neuroplasticity and its focus on our power to influence the function and the structure of the brain, the talk will propound how Langerian mindfulness may provide alternative ways of looking at schema, cognition, thinking, and decision-making. The brain is an information-processing machine adjusting itself to the environment. Information processing is performed to reduce uncertainty, which is inherently present in a changing environment. Perception can be seen as Bayesian inference, where an intention-driven prediction is actively looked in the environment to update the prediction.The percept itself is an emerging pro...

“…The discrimination task performances correlated significantly with performance in the amplitude control task. Evidence that some subjects can use the intertrial interval (ITI) to predict the correct responses in the discrimination task led to an examination of how ITIs were distributed with respect to success (correct or incorrect) and type of trial (same or different from previous) in these and 40 additional subjects from archival data (Frederick, 2012). This analysis found that some information about the correct responses was conveyed by the ITI, but participants made relatively little use of this information.…”

“…Therefore, in the present study, the minimum ITI was set for 8.1 s, and the null hypothesis was that there would be no advantage to perseverative responding on short ITI trials. To allow further comparison, the same hypothesis was examined in archival data (Frederick, 2012) from 40 subjects.…”

The relationship between discrimination and control of physiological states is largely unexplored, although it is often suggested that this relationship is important for the mechanism of action of biofeedback. This pilot study examined 6 participants given seven sessions of alpha discrimination training combined with standard neurofeedback "control" training. Four subjects achieved five criterion (binomial p < .05) sessions in the discrimination task. The discrimination task performances correlated significantly with performance in the amplitude control task. Evidence that some subjects can use the intertrial interval (ITI) to predict the correct responses in the discrimination task led to an examination of how ITIs were distributed with respect to success (correct or incorrect) and type of trial (same or different from previous) in these and 40 additional subjects from archival data (Frederick, 2012). This analysis found that some information about the correct responses was conveyed by the ITI, but participants made relatively little use of this information. However, the criterion discrimination sessions showed dramatic changes in the distribution of ITIs in the present (but not the archival) study, suggesting that participants were controlling their electroencephalogram (EEG) during these sessions. These findings provide preliminary evidence of generalization of skills between these two tasks.

“…Pavlov theory of conditioned reflexes and its development in the studies devoted to human EEG operant conditioning [2]. Due to the researches showing the capabilities of voluntary rearrangement and overfitting of brain wave patterns using a conditioning principle there was formed a biocontrol technology with feedback by EEG, or neurofeedback (NFB) [3].…”

Brain-computer interface and neurofeedback technologies are unique techniques to modulate brain activity based on an operant conditioning. From the time these technologies appeared in the 60-ies of the XX c., they have become non-drug tools for numerous psychiatric and neurologic disorders. However, up to now their efficiency is a matter of debate. Our review considers the background, characteristic features and current state of the technologies. The emphasis was made on the analysis of capabilities and prospects of the technologies in clinical medicine to mobilize the plasticity mechanisms of brain neural network. The review presents the findings of our own experiments showing the future of brain-computer interface and neurofeedback technologies to depend on multi-type cooperation of neurologists, neurobiologists, engineers and mathematicians. Effective consolidation of several fields of science will enable to develop novel therapeutic regimens to restore and improve neural, cognitive and behavioral functions.
