Vestibular and active self-motion signals drive visual perception in binocular rivalry

Summary: Multisensory integration helps the brain build reliable models of the world and resolve ambiguities. Visual interactions with sound and touch are well established but vestibular influences on vision are less well studied. Here, we test the vestibular influence on vision using horizontally o...
