STOCHASTIC RESONANCE IN LIQUID MEMBRANE OSCILLATOR

The oil/water liquid membrane oscillator which has been intensively in vestigated in recent years is generally considered a promising model f or excitable biomembranes. The present work deals with the stochastic resonance (SR) phenomena liquid membrane oscillators with the model pr oposed by Yoshikawa, and the mechanism of SR and some interesting beha viors are also discussed. When SR occurs, the input signal is greatly amplified with the cooperation of noise and the output signal-to-noise ratio is also dramatically enhanced. We consider SR as a possible fun ctional mechanism of some sensory cells. (C) 1998: American Institute of Physics. [S0021-9606(98)50238-3].
