Abstract

The existence of periodic solutions is proven for some neuroscience models with a small parameter. Moreover, the stability of such solutions is investigated, as well. The results are based on a theoretical research dealing with the functional differential equation with parameters x(t)=L(τ) xt + ε f(t, xt), where L: ℝ+→ L(C; ℝ) and f: ℝ × C → ℝ are, respectively, linear and nonlinear operators, and ε>0 is a small enough parameter. The theoretical results are applied to a Parkinson's disease model, where the obtained conclusions are illustrated by numerical simulations.
