Characteristics and Mechanism of Perverted Head-Shaking Nystagmus in Central Lesions: Video-Oculography Analysis

Perverted head-shaking nystagmus (HSN) refers to the nystagmus that is evoked in the plane other than that being stimulated during head shaking (cross-coupled response) (Leigh and Zee 2006). It is mostly downbeat after horizontal head shaking either in the presence or absence of horizontal nystagmus (Leigh and Zee 2006).
