Can anybody explain the neurophysiological mechanisms behind the signs & Sx
observed in otolith & saccade syndromes? is it due to over-activity of the
unopposed contralateral vestibular nucleus/vestibulocerebellum or?

particularly,

otolith:
ipsilateral skew deviation
ipsilateral head-tilt
ipsilateral pulsion of body

saccade:
ipsilateral lateropulsion
vertical saccades deviate to ipsilateral.




Thanks heaps.
