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

1998 
: The aim of the study was an evaluation of the influence that agonists and antagonists of the cholinergic and adrenergic transmission have on the acquisition and retention of habituation in a pigeon. Habituation training was performed by a rotatory test, under specific drugs influencing cholinergic and adrenergic transmission. The results show that after injection of a cholinergic antagonist or adrenergic agonist the acquisition of habituation is quicker; on the contrary, cholinergic agonists or adrenergic antagonists make this process slower. These drugs do not have any influence on the retention of habituation.
