[Modeling of the Otolith's structure and functions].

Physical and chemical processes of the transformation of mechanic stimuli into nerve signals in the otolith responsible for gravity and linear accelerations perception are of interest of equally biologists and experts in aerospace medicine. A severe experimental difficulty is the small size of the otolith and, therefore, mathematical and computer modeling has become a powerful tool for examination of the otolith organs. Most of the above processes are spatially distributed; consequently, spatial distribution models will provide the exact description of the existing biological structures and processes. The review is dedicated to these models and their applicability to demonstrate the variety of processes associated with the otolith.
