Event-related desynchronization (ERD) and synchronization (ERS) in the individually defined theta, alpha-1, alpha-2 and alpha-3 frequency bands were measured in 20 healthy subjects in response to International Affective Picture System (IAPS) stimuli with low, moderate and high arousal (LA, MA and HA) content. The 62-channel EEG, skin conductance response (SCR) and heart rate (HR) were simultane...

We studied the band structure of $\mathrm{Nd}\phantom{\rule{0.16em}{0ex}}\mathrm{Fe}\phantom{\rule{0.16em}{0ex}}{\mathrm{As}}_{1\ensuremath{-}x}{\mathrm{P}}_{x}{\mathrm{O}}_{0.9}{\mathrm{F}}_{0.1}$ ($x=0$, 0.2, 0.4, and 0.6) using angle-resolved photoemission spectroscopy (ARPES) measurements. Two hole bands, ${\ensuremath{\alpha}}_{1}$ $({d}_{xz})$ ${\ensuremath{\alpha}}_{3}$ $({d}_{{z}^{2}})$...

An unusual lipoprotein pattern on polyacrylamide-gel disc-electrophoresis was observed in 37 year-old male diagnosed as alcoholic liver injury. The electrophoretic lipoprotein pattern consisted of a major band of pre-beta mobility and minor intermediate, fast-beta and slow-alpha bands. The normal beta band was virtually absent and the alpha band was diminished. The abnormal lipoprotein pattern ...

In this study, we used a novel multisensory attention paradigm to investigate attention-modulated cortical oscillations over a wide range of frequencies using magnetencephalography in healthy human participants. By employing a task that required the evaluation of the congruence of audio-visual stimuli, we promoted the formation of widespread cortical networks including early sensory cortices as...

This research was designed to evaluate the changes that might occur to protein production after nuclear transfer. Eight-cell stage pig embryo nuclei were transferred to enucleated metaphase II oocytes. Twelve hours after nuclear transfer the nuclear transfer embryos were labeled with L-[35S] methionine and subjected to 1-dimensional polyacrylamide gel electrophoresis. During normal pig embryo d...

Through an extensive series of high-precision numerical computations the optimal complete photonic band gap (PBG) as a function dielectric contrast $\ensuremath{\alpha}$ for variety crystal and disordered heterostructures, we reveal striking universal behaviors sensitivity $\mathcal{S}(\ensuremath{\alpha})\ensuremath{\equiv}d\mathrm{\ensuremath{\Delta}}(\ensuremath{\alpha})/d\ensuremath{\alpha}...

Alpha-frequency band oscillations have been shown to be one of the most prominent aspects of neuronal ongoing oscillatory activity, as reflected by electroencephalography (EEG) recordings. First thought to reflect an idling state, a recent framework indicates that alpha power reflects cortical inhibition. In the present study, the role of oscillations in the upper alpha-band (12 Hz) was investi...

The aim of this study was to determine the effects of alpha neurofeedback and EMG biofeedback protocols for improvement of musical performance in violinists. The sample consisted of 12 music students (10 violinists and 2 viola players) from the Faculty of Music, Skopje (3 males, mean age of 20 +/- 0 and 9 females, mean age = 20.89 +/- 2.98). Six of them had a low alpha peak frequency (APF) (< 1...

Vision identifies objects rapidly and efficiently. In contrast, object recognition by touch is much slower. Furthermore, haptics usually serially accumulates information from different parts of objects, whereas vision typically processes object information in parallel. Is haptic object identification slower simply due to sequential information acquisition and the resulting memory load or due to...
