Plasticity of the human vestibulo-ocular reflex during off-vertical axis rotation

We hypothesize that attenuation of VOR gain increase after the X2 adaptation paradigm is caused by tilt suppression. In the X0 adaptation paradigm, the decrease in VOR gain was facilitated by tilt suppression in addition to the plastic change of the VOR gain caused by visual-vestibular conflict stimulation. Consequently, the VOR gain change ratio in the X0 adaptation paradigm increased significantly compared to that in the X2 adaptation paradigm.
