The vestibular system is the dominating sensory element to detect head/body motion. The encoded signals are essential to stabilize gaze and posture during locomotion, to control autonomic function, and to update navigation circuits to orient and navigate in space. Thus, all animals require functional peripheral structures and pathways as well as central networks to ensure adequate sensory–motor transformations that allow efficient locomotor activity as soon as the respective motor elements have been developed. The diversity of endorgans and neuronal elements in the inner ear are formed through precise genetic instructions and timelines. These latter events create parallel and sequential elements that allow the encoding and transmitting of spatially and dynamically diverse sensory information during body motion in space. During this period, neural computations must be rapidly implemented to ensure the execution of adequate behavioral reactions that generate visual and postural stability. Accordingly, the developmental establishment of a functional vestibular system is key for goal-oriented locomotion
