Neuronal spike-train responses in the presence of threshold noise.
The variability of neuronal firing has been an intense topic of study for many years. From a modelling perspective it has often been studied in conductance based spiking models with the use of additive or multiplicative noise terms to represent channel fluctuations or the stochastic nature of neurotransmitter release. Here we propose an alternative approach using a simple leaky integrate-and-fi...
متن کاملAge and Gender Effects On Auditory Brain Stem Response (ABR)
Objectives: Auditory Brain Stem Response (ABR) is a result of eight nerve and brain stem nuclei stimulation. Several factors may affect the latencies, interpeak latencies and amplitudes in ABR especially sex and age. In this study, age and sex influence on ABR were studied. Methods: This study was performed on 120 cases (60 males and 60 females) at Akhavan rehabilitation center of university...
متن کاملNeuronal Adaptation in Cat Auditory Cortex
Neuronal adaptation – the decline over time of neuronal responses to sensory stimuli – is ubiquitous in all sensory brain areas, especially in the cortex. Adaptation has been implicated in several functional roles, mostly related to the ability of adaptation to improve the neural coding of new incoming stimuli, given a certain stimulus ensemble. Thus, adaptation has been shown to optimize infor...
متن کاملSpike-Threshold Variability Originated from Separatrix-Crossing in Neuronal Dynamics
The threshold voltage for action potential generation is a key regulator of neuronal signal processing, yet the mechanism of its dynamic variation is still not well described. In this paper, we propose that threshold phenomena can be classified as parameter thresholds and state thresholds. Voltage thresholds which belong to the state threshold are determined by the 'general separatrix' in state...
متن کاملSpike-Threshold Adaptation Predicted by Membrane Potential Dynamics In Vivo
Neurons encode information in sequences of spikes, which are triggered when their membrane potential crosses a threshold. In vivo, the spiking threshold displays large variability suggesting that threshold dynamics have a profound influence on how the combined input of a neuron is encoded in the spiking. Threshold variability could be explained by adaptation to the membrane potential. However, ...
