Firing rate relationship in the saccade system neural pathway.
This paper describes the relationship among the structures of the brain involved in the control of the saccadic system. The eye position information is pre-processed by the cerebral cortex and then projected to the cerebellum where this signal is propagated to several structures that are in charge of the control and correction of the eye movement signal. Once this processing is completed, the output is propagated to the final neural stage (the motor neurons), and then to the Rectus and Oblique group of muscles of the eye. In our simulated model, the interaction of the different areas in this neural pathway and its feedback loops is shown through the correlation of the different firing rates of each structure, including background or spontaneous activity components. In order to improve portability the model is implemented with the Matrix Laboratory Language (MATLAB) and the Simulink toolbox.
