摘要：大脑神经元的活动是在复杂的生理学环境下工作的,而生理学环境中的噪声来源于多个方面.如何定量地正确评估神经系统中的噪声环境是神经信息处理的基本问题.本文通过神经能量的计算给出了噪声对神经元膜电位及对应的能量波形产生显著影响的临界值的估计范围,从而定义了神经元赖以活动的生理学意义上的噪声环境.
Neuronal activity in human brain performs in a complex physiologic environment, and the noise in physiologic environment affects all aspects of nervous-system function. An essential issue of neural information processing is that whether we can estimate and quantify the environmental noise in a neural system in a proper way. This paper calculated the neural energy to estimate the range of critical values of noise intensity, which has remarkable effect on the membrane potential and the energy waveform, so as to define such noisy environment on which neuronal activity relies in a physiologic sense.
