showing the locomotor behavior of a tilted mouse (dark brown) and a vestibular-deficient mouse IsK -/- (light brown). The absence of all vestibular signals in IsK -/- during development leads to head-bobbing, waltzing behavior, and episodes of high-velocity circling (body rotations of up to ~1000°/sec). In contrast, the tilted mouse mutant shows a postural deficit, but little locomotor impairment. Note that the movie is at normal speed.
