Alpha-theta neurofeedback has been shown to produce professionally significant performance improvements in music students. The present study aimed to extend this work to a different performing art and compare alpha-theta neurofeedback with another form of biofeedback: heart rate variability (HRV) biofeedback. Twenty-four ballroom and Latin dancers were randomly allocated to three groups, one re...

Optical characteristics and construction of a focusing device for collecting low-energy n-mesons in a solid angle of about 4nsr are considered. The focusing device is an axially-symmetric magnetic lens with magnetic field of ~ 100 kOe and pulsating current of ~ 1.4 MA. Parameters of a supply system operating at several hertz rate are given. At area of 100 cm 2 in the focus plane of the system t...

Introduction Interpreting quantitative EEG results and correlating symptoms can be difficult when there is more than a single contributor or aberrant finding. The clinician may be forced to make decisions with their best estimate of where to begin with neurofeedback interventions. In these cases there are many sites which appear to be equally contributing to the cause leaving the clinician with...

Abstract Previous studies showed that alpha/delta ratio neurofeedback was effective in reducing unpleasant psychological, emotional, and perceptual consequences of tinnitus. The main goal the present study to investigate, whether specific combination enhancing alpha- delta frequency band activity necessary, or merely sufficient, obtain a positive treatment outcome regarding tinnitus distress in...

Indiana University is operating a Low Energy Neutron Source which provides cold neutrons for material research and neutron physics and MeV energy for the neutron radiation effects studies. Neutrons are being produced by a 13 MeV proton beam incident on a Beryllium target. The LENS Proton Delivery System (PDS) is routinely operating at 13 MeV and 25 mA at 1.8% duty factor. The RF system, consist...

At Fast Neutron Research Facility, the 150 kV-pulses neutron generator is being upgraded to a 280-kV-pulsedHe beam for time-of-flight Rutherford backscattering spectrometry. It involves replacing the existing beam line elements by a multicusp ion source, a 400-kV accelerating tube, 45-double focusing dipole magnet and quadrupole lens. The multicusp ion source is a compact filament-driven of 2.6...

Neurofeedback-guided motor imagery training (NF-MIT) has been suggested as a promising therapy for stroke-induced motor impairment. Whereas much NF-MIT research has aimed at signal processing optimization, the type of sensory feedback given to the participant has received less attention. Often the feedback signal is highly abstract and not inherently coupled to the mental act performed. In this...

Activation of the ventral tegmental area (VTA) and mesolimbic networks is essential to motivation, performance, and learning. Humans routinely attempt to motivate themselves, with unclear efficacy or impact on VTA networks. Using fMRI, we found untrained participants' motivational strategies failed to consistently activate VTA. After real-time VTA neurofeedback training, however, participants v...

Consistent empirical results showed that both night and day sleep enhanced memory consolidation. In this study we explore processes of consolidation of memory during awake hours. Since theta oscillations have been shown to play a central role in exchange of information, we hypothesized that elevated theta during awake hours will enhance memory consolidation. We used a neurofeedback protocol, to...
