Abstract
The main topic of this thesis is to specialize mathematical methods and construct stochastic models for describing and predict biological dynamics such as neuronal firing and acto-myosin sliding.
The apparently twofold theme on which we focused the research is part of a strictly unitary context as the methods and tools of investigation adapt naturally to both issues. Models describing the stochastic evolution in the case of neuronal activity or that of the acto-myosin dynamics are governed by stochastic differential equations whose solutions are diffusion processes and Gauss-Markov processes. Of fundamental importance in the study of these phenomena is the determination of the density of the first passage times through one or two time-depending boundaries. For this purpose the development or use of numerical solution algorithms and the comparison of the results with those obtained by simulation algorithms is essential. A particular type of Gauss-Markov process (the time-inhomogeneous Ornstein-Uhlenbeck process) and its first passage time through suitable boundaries are fundamental for modeling phenomena subject to additional (external) time-dependent forces.
