神经脉冲串的普适统计行为

Universal Statistical Behavior of Neural Spike Trains

N. Brenner, O. Agam, W. Bialek, R. de Ruyter van Steveninck

摘要:

我们构建了一个模型,预测由感觉神经元产生的尖峰序列的统计特性。该模型描述了神经元的内在属性,周围的噪声和外部驱动刺激的综合影响。我们发现,尖峰列车在短时间内表现出普遍的统计行为,调制的强烈刺激依赖的行为在很长一段时间。这些预测在对H1的实验中得到了证实,H1是苍蝇视觉系统中的运动敏感神经元。

英文摘要:

We construct a model that predicts the statistical properties of spike trains generated by a sensory neuron. The model describes the combined effects of the neuron's intrinsic properties, the noise in the surrounding, and the external driving stimulus. We show that the spike trains exhibit universal statistical behavior over short times, modulated by a strongly stimulus-dependent behavior over long times. These predictions are confirmed in experiments on H1, a motion-sensitive neuron in the fly visual system.
