We address existence of moving gap solitons (traveling localized solutions) in the Gross-Pitaevskii equation with a small periodic potential. Moving gap solitons are approximated by the explicit localized solutions of the coupled-mode system. We show however that exponentially decaying traveling solutions of the Gross-Pitaevskii equation do not generally exist in the presence of a periodic pote...

Bath application of N-methyl-aspartate induces fictive locomotor activity in the isolated spinal cord preparation of the lamprey, as well as TTX-resistant membrane potential oscillations in many individual neurons. This inherent oscillatory activity is shown to depend on a specific activation of N-methyl-D-aspartate (NMDA) receptors. This activation initiates voltage-dependent, magnesium-requir...

in order to identify the effects of vitamin b 12 and folic acid in reducing methanolinduced retinopathy, erg waves were compared before and after methanol intoxication in rabbits. in this study 34 rabbits were divided into 4 groups. all groups received 4 g/kg of methanol intraperitoneally. in addition, the second, third and fourth groups received vitamin b 12 injection, oral folic acid and a mi...

For decades, oscillatory brain activity has been characterized primarily by measurements of power and phase. While many studies have linked those measurements to cortical excitability, their relationship to each other and to the physiological underpinnings of excitability is unclear. The recently proposed Function-through-Biased-Oscillations (FBO) hypothesis (Schalk, 2015) addressed these issue...

We consider a regularized Wigner equation with an oscillatory kernel, the regularization acts in the space variable to damp high frequencies. The oscillatory kernel is directly derived from the Schrödinger equation with an oscillatory potential. The problem therefore contains three scales, ε the oscillation length, θ the regularization parameter, δ the potential lattice. We prove that the homog...

The oscillatory potential was recorded with photopically balanced monochromatic stimuli in normal eyes. This potential was almost constant both in amplitude and in latency at a range from 500 to 600 nm. The amplitude had a tendency to decrease at both shorter and longer wavelengths. The latency lengthened slightly at each end of the spectrum. The individual wavelets of the oscillatory potential...

Stimuli in simple oddball target detection paradigms cause evoked responses in brain potential. These responses are heritable traits, and potential endophenotypes for clinical phenotypes. These stimuli also cause responses in oscillatory activity, both evoked responses phase-locked to stimulus presentation and phase-independent induced responses. Here, we investigate whether phase-locked and ph...
