...Stephen Young; Victoria A. Taylor ABSTRACT Polyphemus chases were video-recorded in a laboratory tank, and the positions and orientations of the chaser and target were digitized at 100-ms intervals. Analysis of the resulting track reveals three main phases: chaser pauses, shadowing prey...

...Stephen Young ABSTRACT 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. The model was checked against new observations of Polyphemus eye movements...

...Stephen Young; Victoria A. Taylor ABSTRACT Polyphemus eye movements were recorded in both pitching and yawing planes, both in a static visual environment and with a sinusoidally moving stimulus. Spontaneous eye movements (average amplitude 1·7°) had different properties in the two planes...
