We investigated the mechanisms that contribute to spontaneous regular bursting in adult Purkinje neurons in acutely prepared cerebellar slices. Bursts consisted of 3-20 spikes and showed a stereotypic waveform. Each burst developed with an increase in firing rate and was terminated by a more rapid increase in firing rate and a decrease in spike height. Whole-cell current-clamp recordings showed...

In a class of non-Hermitian quantum walk in lossy lattices with open boundary conditions, an unexpected peak the distribution decay probabilities appears at edge, dubbed edge burst. It is proposed that burst originated jointly from skin effect (NHSE) and imaginary gaplessness spectrum [Wen-Tan Xue et al., Phys. Rev. Lett. 128, 120401 (2022)]. Using particular one-dimensional lattice nonuniform ...

23 The reported effects of atrial natriuretic peptide (ANP) on sympathetic nerve activity (SNA) 24 are variable, dependent on concomitant hemodynamic actions and likely to be regionally 25 differentiated. There are few reports of the effect of B-type natriuretic peptide (BNP) on SNA 26 and none have measured cardiac SNA (CSNA) by direct microneurography. 27 We measured the effects of low dose A...

Transmission Control Protocol (TCP) performance over optical burst switching (OBS) is experimentally investigated on an OBS network testbed. The effect of burst losses on TCP performance over the OBS testbed is studied and the result shows that burst losses will lead to a network wide drop in TCP throughput and there exists an optimal assembly period to maximize the available TCP bandwidth. The...

In Optical Burst Switched (OBS) networks a burst may occupy a wavelength on one or more links as it travels through the network. In the literature, OBS networks have been analyzed assuming that each burst occupies only a wavelength on a single link. In this paper, we study analytically the performance of an OBS network with a mixture of different size bursts. The short bursts occupy a wavelengt...

Voice onset times ~VOT! and burst frequencies of two aspirated ~i.e., /k /, /g/) and two unaspirated ~i.e., /k/, /g/! Gujarati velar stop consonants were investigated in an effort to provide characteristic acoustic information. Stop consonants in a monosyllabic vowel–consonant–vowel ~VCV! production were obtained from eight native speakers of Gujarati. Differences in mean VOT and burst frequenc...

Tachykinins are present in lamprey spinal cord. The goal of this study was to investigate whether an endogenous release of tachykinins contributes to the activity of the spinal network generating locomotor activity. The locomotor network of the isolated lamprey spinal cord was activated by bath-applied N-methyl-D-aspartate (NMDA) and the efferent activity recorded from the ventral roots. When s...

In this paper the effect of dynamic wavelength allocation (DWA) scheme implementation to the OBS node performance is investigated. We have developed the mathematical model of an OBS node in order to evaluate the burst blocking probability. It is proposed to allocate a part of total wavelength capacity to be used by deflected bursts only. The results obtained from the model show that if the numb...

The thalamus has been proposed to play a role in sensory modulation via switching between tonic and burst dual firing of individual neurons. Of the two firing modes, altered burst firing has been repeatedly implicated with pathological pain conditions, which suggests that maintaining a certain form of thalamic burst could be crucial for controlling pain. However, specific elements of burst firi...
