Abstract

The behavior of 102 vestibular neurons during optic nystagmus was investigated in 25 guinea pigs with extracellular microelectrodes. The recorded vestibular neurons were electrophysiologically identified by their orthodromic response to ipsilateral labyrinthine stimulation and by antidromic activation from the medial longitudinal fascicle. Of the 102 recorded units, 92 were modulated by the electrical stimulation of at least one optic nerve. The presence of vestibular neurons sensitive to the direction of nystagmus induced by labyrinthine or optic stimulation was also analyzed.
