Keeping the body balance is one of the most important objectives of a person in relation to the environment. For this objective are working together the locomotion system, the nervous system and the sensing organs. Because of its importance there are a lot of published papers on the body balance subject.

Most of the published papers are using statistical instruments on some test results. These mentioned results are obtained applying gait equilibrium tests, using test platforms, on groups of human subjects. We preferred to make a model of balance function, using affordable hardware and software instruments and verify it on theoretical cases to be applied in future practice for real cases.

First, we taken the general feedforward mathematical model of three excitable cells, available in other published papers and then applied it to the interconnecting architecture of neurons inside cerebellum. We simulated the mathematical model obtained for the cerebellum, for some theoretical parameters, in MATLAB, resulting in a set of curves for a set of optimized parameters. We realized a simulation schematic in LTSpice with user defined blocks for neurons and synapses, already published in recent papers, and parametrized them using the optimized parameters obtained after the simulations in MATLAB. We simulated disturbances using the simulation schematic in LTSpice and verified that the results were according with the reality, adjusting the parameters.

Our paper gives us the opportunity to confirm some of the known facts about the nervous system but also to meet into discussion some characteristics with which we were not aware of. Improving the simulation elements and adding some calculus power only the imagination could be the limit of the number of simulated situations.
