Facts (generated by robot; please edit if you find it inaccurate)

• We have identified a "substitution" mechanism by which a different type of eye movement is substituted for the movement that would normally be present and stimulated by the inner ear when the head is moved.
• The relationships between saccade amplitude and saccade duration and velocity are so fixed, that is is possible to use them to show whether a particular eye movement is a normal saccade or not.
• [Eye movement is controlled by basal ganglia-induced GABAergic inhibition]Hikosaka O.
• Interference with spatial working memory: an eye movement is more than a shift of attention.
• The finding, published in Neuron, may help push an old debate about how eye movement is controlled toward resolution and help eye surgeons better diagnose and treat disorders such as strabismus (crossed eyes) that lead to misalignment of the eyes.
