Abstract
Noise can alter the response of neurons, enhancing their ability to detect weak inputs. We analyze how the Hodgkin-Huxley equations, a canonical neuron model, respond to white noise stimulation. We show that this model possesses a stochastic attractor, reduced to a unique stochastic equilibrium point that attracts all trajectories.
摘要
噪声可以改变神经元的反应，增强它们检测微弱输入的能力。我们分析了经典神经元模型霍奇金-赫胥黎方程如何对白噪声刺激做出反应。我们表明，该模型具有一个随机吸引子，简化为一个吸引所有轨迹的唯一随机平衡点。
