Vestibular habituation--the effect of cholinergic, adrenergic and histaminergic agents on the process.

Vestibular habituation-the effect of cholinergic, adrenergic and histaminergic agents on the process. The role of cholinergic, adrenergic and histaminergic transmission on the acquisition of vestibular habituation in pigeons is reported. 1. Cholinolytic, adrenomimetic and histaminergic agents probably clear the way for vestibular habituation in pigeons. 2. The cholinomimetic, adrenolytic and antihistaminergic effects probably inhibit the acquisition of habituation in these animals.
