A single ion channel is stochastic; but looking at many of them at once will reveal regularities, slowly approaching a time course as described by the Hodgkin-Huxley model.

ok, imagine you have an oscillation that is not symmetric around 0 (small direct current shift) with some amplitude modulation, for instance with 1/f-dynamics. ➡️ then these 1/f-dynamics will show up in low frequency part of spectrum (red); in addition to around oscillation peak (yellow).
