It is well known that visual targets evoke waves of activity in the visual cortex of freshwater turtles. In this paper we construct an ARMA system realization of the cortical wave generated as a result of both simple stationary flash and moving natural inputs to the cortex. These inputs include video sequences from 'an ocean with moving fish'. The input sequences and the output cortical waves are represented with respect to suitably chosen spatial and temporal bases. The corresponding coefficient sequences are viewed as inputs to and outputs of the ARMA system. The paper discusses system realization using a least squares algorithm.
