fMRI-EEG dynamics of brain activity in volunteers was studied during the course of EEG alpha-stimulation training (20 sessions). Twenty-three healthy men (20-35 years) were subjected to 3-fold mapping in a feedback loop (EEG alpha-rhythm biofeedback with acoustic reinforcement). This procedure was performed at the beginning, middle, and end of the course. During the first neurofeedback training session, deactivation (p<0.001) was found in the right angular gyrus, supramarginal, and superior temporal gyri, Brodmann area 39, and cerebellum...

While biofeedback is often said to increase self-control of physiological states by increasing awareness of their subjective correlates, relatively few studies have analyzed the relationship between control (standard biofeedback) and awareness (a discrimination paradigm). We hypothesized that the two skills would generalize and facilitate each other for 8-12Hz EEG amplitude (alpha). Participants were given 7 sessions of training to either control or discriminate Pz alpha followed by 3 sessions of the other paradigm...

Neurofeedback is a kind of biofeedback, which teaches self-control of brain functions to subjects by measuring brain waves and providing a feedback signal. Neurofeedback usually provides the audio and or video feedback. Positive or negative feedback is produced for desirable or undesirable brain activities, respectively. In this review, we provided clinical and technical information about the following issues: (1) Various neurofeedback treatment protocols i.e. alpha, beta, alpha/theta, delta, gamma, and theta; (2) Different EEG electrode placements i...

The cerebral cortex provides sensorimotor integration and coordination during motor control of daily functional activities. Power spectrum density based on electroencephalography (EEG) has been employed as an approach that allows an investigation of the spatial-temporal characteristics of neuromuscular modulation; however, the biofeedback mechanism associated with cortical activation during motor control remains unclear among elderly individuals. Thirty one community-dwelling elderly participants were divided into low fall-risk potential (LF) and high fall-risk potential (HF) groups based upon the results obtained from a receiver operating characteristic analysis of the ellipse area of the center of pressure...

A stroke is caused when an artery carrying blood from heart to an area in the brain bursts or a clot obstructs the blood flow to brain thereby preventing delivery of oxygen and nutrients. About half of the stroke survivors are left with some degree of disability. Innovative methodologies for restorative neurorehabilitation are urgently required to reduce long-term disability. The ability of the nervous system to reorganize its structure, function and connections as a response to intrinsic or extrinsic stimuli is called neuroplasticity...

BACKGROUND: The assessment of the functional activity of the brain in hypertensive patients is a prerequisite for an adequate treatment, but it is often limited to blood pressure parameters monitoring and rarely used in practice. Nevertheless, the proper functioning of the central nervous system is precisely a reaction to any influence, including therapy and biofeedback intervention, and allows for quality evaluation of the selected treatment. We aimed to determine the efficiency of combining heart rate variability biofeedback (HRV-BF) with pharmacological therapy in order to keep the normal brain activity in stage I hypertensive patients...

EEG Biofeedback (also known as neurofeedback) has been in use as a clinical intervention for well over 30 years; however, it has made very little impact on clinical care. One reason for this has been the difficulty in designing research to measure clinical change in the real world. While substantial evidence exists for its efficacy in treating attention deficit/hyperactivity disorder, relatively little evidence exists for its utility in other disorders including posttraumatic stress disorder (PTSD). The current study represents a "proof-of-concept" pilot for the use of neurofeedback with multiply-traumatized individuals with treatment-resistant PTSD...

Swallowing and swallowing disorders have garnered continuing interest over the past several decades. Electroencephalography (EEG) is an inexpensive and non-invasive procedure with very high temporal resolution which enables analysis of short and fast swallowing events, as well as an analysis of the organizational and behavioral aspects of cortical motor preparation, swallowing execution and swallowing regulation. EEG is a powerful technique which can be used alone or in combination with other techniques for monitoring swallowing, detection of swallowing motor imagery for diagnostic or biofeedback purposes, or to modulate and measure the effects of swallowing rehabilitation...

BACKGROUND: Approximately 30% of patients with epilepsy remain refractory to drug treatment and continue to experience seizures whilst taking one or more antiepileptic drugs (AEDs). Several non-pharmacological interventions that may be used in conjunction with or as an alternative to AEDs are available for refractory patients. In view of the fact that seizures in people with intellectual disabilities are often complex and refractory to pharmacological interventions, it is evident that good quality randomised controlled trials (RCTs) are needed to assess the efficacy of alternatives or adjuncts to pharmacological interventions...
