The aim of the study was to estimate the influence of hemispherectomy and hemicerebellectomy on acquisition and retention of vestibular habituation in pigeons. The habituation training was performed using a rotatory test. The frequency of head nystagmus and postural reflexes was examined before and after acquisition of habituation and some days later, for the evaluation of the retention process. Our results suggested that the hemispherectomy did not inhibit the acquisition of habituation but retention of this phenomenon was shorter at that time. The hemicerebellectomy made it impossible to reveal the vestibular habituation.
