Parameter dependence of the frequency response. (A) Amplitude-frequency characteristics in the sealed end (x = 0) depending on the shunt conductance g. (B, 1 and 2) Amplitude-frequency characteristics and normalized characteristics in the shunt end (x = L), depending on g. Here, the membrane time constant τ = 45 ms. (C) Preferred frequency maximizing the amplitude response at the shunt end (x = L) depending on g and τ. (D) Amplitude at 0 Hz in the sealed end (x = 0) depending on g and τ. (E) Amplitude maximized at the preferred frequency in the shunt end (x = L) depending on g and τ. These results were obtained from Eq. 22. Depending on these parameters, the preferred frequencies at x = L vary from δ- to β-bands. The dominant frequencies inducing large amplitudes are mainly in δ- and θ-bands. On the other hand, the amplitude of the frequency response at x = 0 becomes larger as g and τ increase.
