Abstract:
A saccade is a fast spasmodic movement of an eye formed by the central nervous system before the beginning of the movement and is realized by oculomotor muscles as a programmed movement. These muscles are modeled as viscoelastic contractile elements. The programmed control is defined as a time function and is considered as a sum of four components (tonic, static, kinematic, and dynamic) under the following assumption: when a muscle contracts, the corresponding antogonistic muscle becomes elongated.
Key words:saccade, eye, extraocular muscles, movement programming.
