Low-Beta (15-20Hz) Neurofeedback and Motor Performance

Low-Beta (15-20Hz) Neurofeedback and Motor Performance

EEG Neurofeedback Training (NFT) is a non-invasive neurophysiological technique, aimed at facilitating learned self-regulation of electrical activity of the brain. Beyond research into clinical applications of neurofeedback, a relative surge of interest into the methodology has led to attempts to apply EEG neurofeedback as a means to facilitate performance enhancement among non-clinical populations. One such domain is the enhancement of athletic performance and motor function. While significant attempts have been undertaken to investigate outcomes of sensori-motor rhythm (12-15Hz) modulation on aspects of motor performance, research exploring behavioural outcomes of EEG-NFT targeting the beta frequencies (15-20Hz) appear scarce.

Based upon the current platform of research, measures of beta, and beta activity of the primary motor cortex have been evidenced to relate to aspects of motor skill acquisition and learning – and likely as a process underlying motor inhibition. Support for such claims may be seen in research highlighting excessive beta frequency activity in individuals with disorders of motor function, and increased event-related beta desynchronization among elite vs amateur athletes. As such, the current research project attempts to investigate behavioural outcomes directly following beta EEG-NFT, as measured by a dart-throwing accuracy task and a visual Go/NoGo task measuring inhibitory processes.

Consisting of 17 participants, the project employs a double-blind design with each participant undertaking two 30-minute sessions of neurofeedback across two testing conditions. Both participant and facilitator are blind to the feedback condition. It is hypothesised that within the beta+ (increase) condition, participants will evidence an improvement in dart-throw accuracy, as compared to results from the beta-(decrease) condition. It is hypothesised that within the beta+ condition, participants will evidence reduced errors of commission and omission, alongside increases of reaction time within a modified Go/NoGo performance task as compared to the beta- condition.

Deep Trauma; Deep Inquiry; Deep Holding: The role of the therapist in the integration of neurofeedback and psychotherapy

Regardless of the kind of therapy we practice, the primary treatment goal with those who have suffered developmental trauma is affect regulation. Neurofeedback can teach brains how to quiet their own limbic eruptions and ease the pulses of fear, shame and rage that overtake these patients.  Developmental trauma is, however, a relational disorder. At its core is the profound experience of motherlessness. This cannot be addressed by neurofeedback alone. With understanding, skill and neurofeedback, psychotherapists can begin to provide an experience of regulation that these patients have not had and with that an experience of having been mothered. This workshop will focus on what the therapist treating developmental trauma must know about the interplay of affect regulation and motherlessness, how neurofeedback can affect the therapy relationship for both patient and therapist and what to anticipate in the therapeutic relationship as you begin to quiet affect. We will touch on the latest developments in the neuroscience of trauma to better understand well- tested and newer protocols for those suffering the aftermath of developmental trauma.

The Inconvenience of Science: When Evidence Challenges Enthusiasm

There have been extraordinary gains in understanding brain dynamics in the last decade. Quantitative EEG and FMRI connectivity studies have done much to better characterise the neural networks that underpin consciousness, as well as different psychopathological states. These demonstrated abnormalities encourage contemplation of the possible therapeutic interventions that may assist in normalising brain function. The literature about the positive benefits of intervention often is based on case series highlighting substantial improvement. However, high quality trials and even the meta analyses of the most investigated disorder, ADHD, have tended to fail to provide the necessary empirical support, for neurofeedback as an intervention.

Applied Neuroscience: Neurofeedback Enhances Executive Functioning

This lecture shows how trauma directly affects the developing brain, and specific brain functions responsible for attention, concentration, regulating emotions and engaging in satisfying relationships. Even after receiving excellent therapy many traumatised children and adults continue to feel chronically on edge, scared, agitated, collapsed and helpless. To deal with this they often try to cope with alcohol or drugs, while doctors prescribe a large variety of different medications that may make life more manageable but that also affect motivation and curiosity, and that rarely really resolve the problem.
