Influence of imaginary target on "dumping" of vestibulo-ocular reflexes and postural control.

ABSTRACT

Two studies explored 1) the effect of instruction set upon the well known "dumping" of the vestibulo-ocular (VOR) post-rotatory nystagmus long time constant (TC) and 2) the effect of imaginary earth-fixed targets on postural control. Imaginary targets do not produce dumping and do not improve postural stability, with or without pitch head movements.
