From a systems analysis perspective, this also derives from nonlinearity, but it need not necessarily scale with the size of the input The second class of mechanisms involves asymmetries in vestibular gain due to a variety of factors, such as lesions to the vestibular nerve or root entry zone, loss of vestibular hair cells, asymmetrical cervical afferent input, or asymmetrical central gain.
Tsutsui J, and Fukai S. Asymmetrical neck input or neck modulation is a very reasonable source of HSN that so far, has gone unexplored.
