Figure 3From: Orientation and disorientation in aviationResponse of the semicircular canal to sustained angular velocity. The increasing angular velocity as a consequence of an angular acceleration over a 2-s period is accurately sensed. If a constant angular velocity is maintained, the cupula gradually returns to its central position, and there is an exponential decay in the sense of rotation. If then a deceleration is initiated, it is sensed as an exponentially decaying sense of rotation in the opposite direction.Back to article page
