[The influence of experimental hemispherectomy and hemicerebellectomy on the acquisition and retention of habituation in pigeon].
The subject of investigation was the analysis of the acquisition and retention of the vestibular habituation in pigeons after hemispherectomy or hemicerebellectomy. The habituation training was performed using rotatory test. The frequency of head nystagmus and postural reflexes were examined before and after acquisition of habituation and some days later, for evaluation of retention. Our results suggests that hemispherectomy does not inhibit acquisition of habituation but retention of this phenomenon is shorter at that time. The hemicerebellectomy makes impossible the vestibular habituation.
