| Abstract: | Stability properties of gravity receptor transduction mechanisms were investigated by recording action potentials from the eighth nerve of cats maintained at two spatial positions both with and without an added click perturbation. The cells were demonstrated to present directional sensitivity, multivaluedness and wandering of mean rate trajectories. To the wandering were fitted appropriate stability boundaries corresponding to recent theories of finite time stability. Results supported the hypothesis that physiological stimuli result in local deformations of a flexible trampoline-like macula. |
