Quick Reference

A reflex turning of the eyes or head in response to the horizontal movement of environmental objects. For example, when a fly (Eristalis sp.) is placed inside a cylinder painted with vertical stripes, it shows a typical optomotor reflex, turning in the direction of the stripes when the cylinder is rotated. Such reflexes do not occur when the fly moves of its own accord, although the visual stimulation is similar. This suggests that some type of reafference principle is involved.
