Fractional-order simulation tool for the brainstem vestibulo-ocular reflex (VOR)

The function of the oculomotor system is to control eye movements. To accomplish this function, oculomotor neural networks generate control signals in order to compensate eyeball dynamics. Existing models describe the dynamics of the eye and of the oculomotor system using integer-order operators. In this paper, a simulation tool that allows to investigate the fractional-order dynamics of the vestibulo- ocular reflex is proposed. Moreover, it will be shown that alterations in oculomotor neural network can be modeled by using fractional-order dynamics, confirming fractionalorder systems’ capability in modeling physical phenomena.
