Abstract
The present paper investigates the existence of periodic oscillations for a delayed Parkinson's disease mathematical model. We extend the result in the literature from stability to oscillation. Two sufficient conditions to guarantee the oscillation of the solutions are provided. Some parameter that affects the oscillation is sensitive from our simulation.
