[The role of the histaminergic receptor in the vestibular habituation: an experimental study].

The aim of the study was to determine the role of histaminergic H1, H2 and H3 transmission on the acquisition of vestibular habituation in pigeons. Rotatory training was used and the intraperitoneal injections of the agonists and antagonists of receptors described above were performed before each training. The results showed that agonists of H1 and H2, and H3 antagonist facilitate vestibular habituation. On the other hand, H1 and H2 antagonists restrain this process.
