The present study evaluated quantitative electroencephalogram (QEEG)-guided and Scott/Peniston neurofeedback compared with a wait-list control in the treatment of substance abuse in an outpatient setting. Participants completed an intake assessment, 40 neurofeedback sessions, and a posttraining assessment. Change scores of the clinical scales of the Personality Assessment Inventory were used fo...

Neurofeedback training involves presenting an individual with a representation of their brain activity and instructing them to alter the activity using the feedback. One potential application of neurofeedback is for patients to alter neural activity to improve function. For example, there is evidence that greater laterality of movement-related activity is associated with better motor outcomes a...

The enzyme Na-K activated ATPase, which is closely related to the active transport system of sodium and potassium in erythrocytes, nerve and other tissues, occurs in relatively high activities in the epithelium of cat, calf, and rabbit lens. No significant activity could be detected in anterior and posterior capsule, cortex, and nucleus. Various properties of the enzyme system were determined a...

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 inf...

Background Effective treatment interventions for criminal offenders are necessary to reduce risk of criminal recidivism. Evidence about deviant electroencephalographic (EEG)-frequencies underlying disorders found in criminal offenders is accumulating. Yet, treatment modalities, such as neurofeedback, are rarely applied in the forensic psychiatric domain. Since offenders usually have multiple di...

In femtosecond laser-assisted cataract surgery, the parameter such as horizontal spot spacing and energy level can be adjusted. Although there have been several studies reported on various laser systems, showing the effects of varying energy levels and horizontal spot spacing on lens capsulotomy cut edges, none have been reported on the Catalys laser system (Abbott Medical Optics, Inc., Santa A...

PURPOSE This study explored the effects of neurofeedback training on Electroencephalogram (EEG), Continuous Performance Task (CPT) and ADHD symptoms in ADHD prone college students. METHODS Two hundred forty seven college students completed Korean Version of Conners' Adult ADHD Rating Scales (CAARS-K) and Korean Version of Beck Depression Inventory (K-BDI). The 16 participants who ranked in th...

Critical branching is a form of theoretical interaction between simple units, which, in the case of the human brain are assumed to be neuronal elements. Zhigalov, Kaplan, & Palva (Clin Neurophysiol 2016;127:2882–89) revealed that neurofeedback flash stimulation phase-locked to high-amplitude occipital alpha influences the stimulus-locked occipital alpha-band averages and the power scaling of lo...

Neurofeedback based on real-time functional magnetic resonance imaging (rt-fMRI) is a novel and rapidly developing research field. It allows for training of voluntary control over localized brain activity and connectivity and has demonstrated promising clinical applications. Because of the rapid technical developments of MRI techniques and the availability of high-performance computing, new met...
