UNILATERAL HABITUATION OF VESTIBULO‐OCULAR RESPONSES IN THE CAT

Vestibular habituation is known to be direction specific. When the animal is submitted to repeated unidirectional accelerations or unilateral calorization (vestibular training), the vestibulo-ocular reflex (VOR) decreases in one direction only.’-4 Unidirectional VOR decline also can be obtained by repeatedly presenting a stationary subject with large visual scenes moving in one direction (optokinetic training]. In that case, the progressive VOR decrease occurs for responses to subject’s rotations in the direction opposite to that of the previous pure visual
