In order to analyze the background wave by Ca2+ion in the neuronal endogenous oscillation, the article presents a three-variable non-linear mathematical model for neuron membrane, and calculates the time sequence of oscillations, bifurcation, chaos on the neuron membrane by Matlab5.

Response characteristics of the descending interneurons in the honeybee (Apis mellifera) to stimulating light and their relation to the different horizontal direction of the stimulating light were studied with electrophysiological exocellular recording method.
