Medio-lateral CoP displacements in GVS trials. The graph show the mean medio-lateral CoP displacement of the deafferented subject recorded in trials with 0.75 mA or 1.5 mA galvanic vestibular stimulations. The GVS produced large lateral shifts of the CoP towards the anode side. The data from the healthy control subjects are not represented as the stimulations were not large enough to induce clear postural responses when seated. See additional file 2: Table 2 for the statistical analyses.
