本征噪声能诱发各种共振峰吗？
Can intrinsic noise induce various resonant peaks?
摘要：
我们从理论上描述了如何弱信号可以有效地传输在一个以上的频率范围内的噪声激励介质的随机多共振。这有助于我们重新解释最近的神经科学实验，并表明自然界中的许多其他系统可能能够表现出几种共振。事实上，在我们的（网络）模型中，观察到的行为是由于（1）传输信号的变化（就好像单元正在改变它们的激活阈值）和（2）模型中实现的自适应噪声（作为连接强度的快速活动依赖性波动）之间的竞争。这两个条件确实是已知的，以表征可兴奋单元的异质网络系统，例如，大脑中的神经元和突触。我们的研究结果也可以在探测器设备的设计中找到应用。
英文摘要：
We theoretically describe how weak signals may be efficiently transmitted throughout more than one frequency range in noisy excitable media by kind of stochastic multiresonance. This serves us here to reinterpret recent experiments in neuroscience, and to suggest that many other systems in nature might be able to exhibit several resonances. In fact, the observed behavior happens in our (network) model as a result of competition between (1) changes in the transmitted signals as if the units were varying their activation threshold, and (2) adaptive noise realized in the model as rapid activity-dependent fluctuations of the connection intensities. These two conditions are indeed known to characterize heterogeneously networked systems of excitable units, e.g., sets of neurons and synapses in the brain. Our results may find application also in the design of detector devices.
