Weak Quasiperiodic Signal Propagation through Multilayer Feed-Forward Hodgkin–Huxley Neuronal Network

Figure 3

Sampled time series of external quasiperiodic signal with an amplitude A and an average frequency ω. represents the Wiener process with the intensity of σ. The departure from the normal periodicity can be governed by the parameter σ. If σ is equal to 0, signals are normal periodic signals. From top to bottom, σ takes values of 0, 0.1, 0.2, 0.3, 0.4, and 0.5, successively.
