O. Meusel, A. Jakob, J. Pozimski, U. Ratzinger, A. Ushakov Institut für Angewandte Physik der Johann Wolfgang Goethe Universität D-60054 Frankfurt am Main Several future applications of high current ion beams require excellent beam quality. Especially the low energy beam transport (LEBT) of high perveance ion beams suffers from high space charge forces [1]. Therefore the IAP places emphasis on ...

OBJECTIVES Alzheimer's disease (AD) is the most common form of dementia. In quantified EEG (qEEG), the AD patients have a greater amount of theta activity compared with normal elderly individuals. Little is known about the effect of neurofeedback in patients with dementia. The objective of this study was to examine whether neurofeedback has a positive effect on cognitive performance in patients...

In this paper we discuss our vision on future neurofeedback therapy. We analyze problems of the current situation and debate for a change in focus towards a vision in which neurofeedback therapy will ultimately be as easy as taking an aspirin. Furthermore we argue for a gaming approach as training, for separation between neurofeedback therapy and gaming has become noticeably smaller after recen...

Neurofeedback is gaining recognition as an efficient, effective treatment for a variety of different psychological and neuropsychiatric disorders. Its value has been shown in robust clinical studies. However, certain percentage clients do not respond to this modality. We suggest performing easier sessions so that receive increased rate positive feedback. This may encourage response neurofeedbac...

We examine the three-dimensional intensity distribution of vector Bessel-Gauss beams with general polarization near the focus of a nonaperturing thin lens. Recently reported linearly and azimuthally polarized Bessel-Gauss beams are members of this family. We define the width and focal plane of such a vector beam using an encircled-energy criterion and calculate numerically that, as for scalar b...

INTRODUCTION This study aimed to evaluate the effectiveness of neurofeedback on attention deficit hyperactivity disorder. METHODS This is a quasi-experimental study without a control group. The study population included all children aged 5 to 12 years old affected with attention deficit hyperactivity disorders in Tehran, Iran who were referred to psychiatric clinics and given the diagnosis. T...

Introduction: Among the components of the extracellular matrix (ECM) and basement membrane (BM), laminitis heterotrimeric glycoprotein (laminin) and collagen type IV are the most important. In a previous study we have examined the role of collagen type IV in the developing lens capsule. The present study aims to determine the appearance and distribution of laminin in the BM and ECM of lenses ...

The motor cortex in humans is more active during exercise than at rest. This study examined the effect of neurofeedback-EEG training, which consisted in a reduction in the amplitude of the beta2 band (20-30 Hz) during exercise, on the results of behavioural tests that evaluated attention, reaction time and the shape of the work curve. The relationships between the EEG bands during exercise and ...

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 f...
