Figure 4.

Tilting responses in persons with unilateral posterior insular lesion and age-matched control participants. The person with right-brain injury showed no differences in tilting responses between conditions. In the person with left-brain injury, finger touches enhanced tilting responses during GVS. In age-matched healthy participants, the right finger touch significantly modulated tilting responses. Error bars represent standard error. Only significant differences between conditions for each participant are shown using asterisks. **p < 0.01, ***p < 0.005, ****p < 0.001.
