Head-shaking nystagmus (HSN) is a transient nystagmus which is a result of a unilateral peripheral hypofunction based on Ewald's second law. This law states that there will be a stronger response of a labyrinth to excitatory than to inhibitory inputs with high-velocity stimuli. This chapter aims to understand the degree to which the HSN may be explained by the two hypotheses — unilateral peripheral hypofunction or asymmetry of central velocity storage — and to evaluate the correlation between HSN and SPN. It is concluded that the horizontal head-shaking maneuver is a highly sensitive method for detecting vestibular asymmetries resulting from the unilateral vestibular hypofunction or imbalance in the central velocity storage.

Keywords:   head-shaking nystagmus, transient nystagmus, hypofunction, high-velocity stimuli, vestibular asymmetries, inhibitory inputs
