Gamma oscillations, now widely regarded as functionally relevant signals of the brain, illustrate that the concept of event-related oscillations bridges the gap between single neurons and neural assemblies. Taking this concept further, we review experiments showing that oscillatory phenomena such as alpha, theta, or delta responses to events are strongly interwoven with sensory and cognitive fu...

Influence of the transverse uniform magnetic field $\bf B$ on position (subscript $\rho$) and momentum ($\gamma$) Shannon quantum-information entropies $S_{\rho,\gamma}$, Fisher informations $I_{\rho,\gamma}$ informational energies $O_{\rho,\gamma}$ is studied theoretically for 2D circular quantum dots (QDs) whose circumference supports homogeneous either Dirichlet or Neumann boundary condition...

in a recent paper, de baets et al. have characterized the fuzzytolerance and fuzzy equivalence relations that a given strict order relation iscompatible with. in this paper, we generalize this characterization by consideringan arbitrary (crisp) relation instead of a strict order relation, while payingattention to the particular cases of a reflexive or irreflexive relation. the reasoninglargely ...

In this study, we systematically studied the X-ray to GeV gamma-ray spectra of 61 {\it Fermi} Large Area Telescope (LAT) detected radio galaxies. We found an anticorrelation between peak frequency and luminosity in high-energy spectral component galaxies, similar blazars. With sample, also constructed a function (GLF) gamma-ray-loud that blazar-like GLF shapes can reproduce their redshift distr...

In this Letter we show that there is a redshift degeneracy in the Eiso–Epeak relation of gamma-ray bursts (GRBs). If a GRB has a redshift solved from the Eiso–Epeak relation that lies in the range of 0.9 < z < 20, a GRB that has the same observed fluence and peak spectral energy but is at a different redshift in that range also satisfies the Eiso– Epeak relation within 1-σ error, implying an ex...

OBJECTIVE There has been a convergence of models describing schizophrenia as a disconnection syndrome, with a focus on the temporal connectivity of neural activity. Synchronous gamma-band (40-Hz) activity has been implicated as a candidate mechanism for the binding of distributed neural activity. To the authors' knowledge, this is the first study to investigate "gamma synchrony" in first-episod...

In this paper we develop the gamma neural model, a new neural net architecture for processing of temporal patterns. Time varying patterns are normally segmented into a sequence of static patterns that are successively presented to a neural net. In the approach presented here segmentation is avoided. Only current signal values are presented to the neural net, that adapts its own internal memory ...

The expression of protein kinase c gamma (PKC gamma) and c-fos protein was examined by means of double labeling in the rat brain in relation to the molecular mechanism of central plastic changes associated with anodal polarization. Under normal, non-polarized condition, approximately 75% of all fos positive neurons in the neocortex were immunopositive for PKC gamma. Conversely, nearly all PKC g...

The number of clinical studies on gamma interferon (IFN-gamma), tumor necrosis factor-alpha (TNF-alpha) and interleukin-4 (IL-4) in human brucellosis is limited. The present study was focused on IFN-gamma, TNF-alpha and IL-4 levels in acute brucellosis cases, in the acute phase and at the end of the treatment. The relation of these cytokines to traditional inflammation markers was also investig...
