引起呼吸暂停的神经活动以复杂的方式波动。显然，膈神经活动的“嘈杂”变化可能表现为分形尺度关系。eupnea的分形标度是在细胞水平上在短时间尺度上作用的物理和化学过程的结果，并且与在较长时间尺度上同时作用的类似过程相关。具体来说，膈神经爆发的变化可能不是独立的随机波动或完全由于短期影响4，但可能表现出分形标度的时间相关性。West和deering20已经证明，分形过程基本上对错误没有反应，并且对生理环境中的变异性非常宽容。在这种观点下，eupnea及其伴随的对来自广谱输入的误差的稳定性必须具有分形的容错特性。
Neural activity which gives rise to eupnea fluctuates in a complex manner. Apparently “noisy” variations in activity of the phrenic nerve may display a fractal scaling relationship. Fractal scaling in eupnea is the consequence of physical and chemical processes acting over short time scales at the cellular level, and which are correlated with similar processes acting simultaneously over longer time scales. Specifically, variations in phrenic neural bursts may not be independent random fluctuations or entirely due to short-range influences4, but may exhibit temporal correlation indicative of fractal scaling. West and Deering20have demonstrated that fractal processes are essentially unresponsive to error and very tolerant of variability in the physiological environment. In this view, eupnea with its concomitant stability to error from a broad spectrum of inputs must have the error-tolerant properties of fractals.
