Why do oVEMPs become larger when you look up? Explaining the effect of gaze elevation on the ocular vestibular evoked myogenic potential

SM Rosengren, JG Colebatch, D Straumann… - Clinical …, 2013 - Elsevier

Understanding and misunderstanding extraocular muscle pulleys

JM Miller - Journal of Vision, 2007 - jov.arvojournals.org
As evidence has mounted for the critical role of extraocular muscle (EOM) pulleys in normal
ocular motility and disease, opposition to the notion has grown more strident. We review the …

Ocular vestibular evoked myogenic potentials (OVEMPs) produced by impulsive transmastoid accelerations

NPM Todd, SM Rosengren, JG Colebatch - Clinical neurophysiology, 2008 - Elsevier
OBJECTIVE: Recent work has demonstrated the existence of ocular vestibular evoked
myogenic potentials (OVEMPs), which likely reflect projections underlying the translational …

T2-weighted fast spin-echo magnetic resonance imaging of extraocular muscles
