The subjective visual vertical (SVV) indicates perceived direction of gravity. Even in healthy human subjects, roll-angle dependent misestimations - roll over-compensation (A-effect, head-roll>60°&<135°) and under-compensation (E-effect, head-roll<60°) - occur. Previously, we demonstrated that, after prolonged roll-tilt, SVV estimates when upright are biased towards the preceding roll position, which indicates that ...
