Tissue hypoxia correlates with intensity of interictal spikes [PDF]
Journal of Cerebral Blood Flow & Metabolism, 2011 Interictal spikes (IISs) represent burst firing of a small focal population of hypersynchronous, hyperexcitable cells. Whether cerebral blood flow (CBF) is adequate to meet the metabolic demands of this dramatic increase in membrane excitability is unknown.

Statistical correlations and intensity spiking in the SASE FEL [PDF]
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2002 Abstract In the linear regime before saturation, we describe the statistical correlations in the narrow band chaotic output of the self-amplified spontaneous emission free-electron laser. At a fixed position along the undulator axis, we derive joint probability distributions for the intensity in the output pulse to have values I1 and I2 at times t1 ...

Rapid odor processing by layer 2 subcircuits in lateral entorhinal cortex
eLife, 2022 Olfactory information is encoded in lateral entorhinal cortex (LEC) by two classes of layer 2 (L2) principal neurons: fan and pyramidal cells. However, the functional properties of L2 cells and how they contribute to odor coding are unclear.

Fast negative feedback enables mammalian auditory nerve fibers to encode a wide dynamic range of sound intensities. [PDF]
PLoS ONE, 2012 Mammalian auditory nerve fibers (ANF) are remarkable for being able to encode a 40 dB, or hundred fold, range of sound pressure levels into their firing rate.

Noise-enhanced coding in phasic neuron spike trains. [PDF]
PLoS ONE, 2017 The stochastic nature of neuronal response has lead to conjectures about the impact of input fluctuations on the neural coding. For the most part, low pass membrane integration and spike threshold dynamics have been the primary features assumed in the ...

NeuroImage, 2021 In process of brain stimulation, the influence of any external stimulus depends on the features of the stimulus and the initial state of the brain. Understanding the state-dependence of brain stimulation is very important.

Burst firing is a neural code in an insect auditory system [PDF]
, 2008 Various classes of neurons alternate between high-frequency discharges and silent intervals. This phenomenon is called burst firing. To analyze burst activity in an insect system, grasshopper auditory receptor neurons were recorded in vivo for several ...

Resistance to Puccinia triticina at different stages of wheat [PDF]
Zbornik Matice Srpske za Prirodne Nauke, 2009 Ten wheat genotypes were tested for resistance characteristics to Puccinia triticina. Infection intensity in the field was evaluated at different growth stages, and time of spike appearance and leaf senescence were recorded.
