Chasing with a Model Eye

Stephen Young 1

1 Department of Pure and Applied Biology, Imperial College, Silwood Park, Ascot, Berks SL5 7PY

1. A simulation model for Polyphemus eye movements was based on an openloop saccadic control system, derived from previous observations of eye movements in response to sinusoidally oscillating targets.

2. The model was checked against new observations of Polyphemus eye movements in response to erratically moving targets.

3. It was used to predict eye movements in response to stimulus patterns deduced from an analysis of video-recordings of Polyphemus chases.

4. The results show that the system is limited to tracking slow target movements, but that this is consistent with observed chasing behaviour.

Key words: eye movement, simulation, Polyphemus.
