AB The  vestibulo-ocular  reflex  (VOR)  has  been  created  with  an  incredible  plasticity  for  the  purpose  of  enabling  change  inevitable  with  disease  and  aging.  In  fact,  without  this  adaptation,  the  normal  effects  of  age  or  the  constant  attacks  from  disease  would  render  us  with  significant  functional  impairments—namely  gaze  and  gait  instability.  Some  examples  of  the  critical  and  extreme  plasticity  within  the  VOR  include  altered  VOR  gain  with  newly  fitted  glasses  and  complete  reversal  of  the  VOR  when  fitted  with  lenses  that  demand  it.  The  focus  of  this  chapter  is  on  evidence  for  VOR  adaptation  from  animal  and  human  studies.  In  particular,  I  focus  on  the  robustness  of  VOR  plasticity,  evidence  for  location  sites  of  such  plasticity,  and  how  this  adaptation  occurs.  For  information  concerning  oculomotor  (e.g.,  compensatory  saccade)  and  vestibulospinal  compensatory  strategies  that  may  assist  a  deficient  VOR,  please  see  Chapters  6  and  9.
