Cholinergic mechanisms in the cat vestibular system.
-A neuropharmacological stud) WBS undertaken in the cat to obtain further evidence of the role ofacetylcholine in vestibular function. It was shown that the vestibular nerve contains about half or less the enzymatic activity of choline acetyltransferase. acetylcholinesterase. cholinesterase and total cholinesterase than nucleus vestlbularls later&s (NVL). Field potentials as well as discharge o...
متن کاملEfferent vestibular system in the toadfish: action upon horizontal semicircular canal afferents.
The influence of the efferent vestibular system (EVS) upon the background discharge and response dynamics of horizontal semicircular canal afferents was examined in the toadfish. In one set of experiments the EVS was activated using a behavioral paradigm; in the second, electrical shocks were applied to the efferent vestibular nucleus in the brain stem. The afferent's background discharge and r...
متن کاملA ROTATORY MANEUVER TO REDUCE IMBALANCE OF THE VESTIBULAR SYSTEM IN PATIENTS WITH VESTIBULAR VERTIGO
In an attempt to diminish the intensity of vertigo, this study was designed to reduce the imbalance between the vestibular system on the two sides. By rotating the subjects with a string-activated rotating chair in opposite direction of the dominant side, the dominant side would be inhibited and simultaneously the subordinate ide would be stimulated. Eight patients with vestibular vertigo c...
متن کاملReviewing the Role of the Efferent Vestibular System in Motor and Vestibular Circuits
Efferent circuits within the nervous system carry nerve impulses from the central nervous system to sensory end organs. Vestibular efferents originate in the brainstem and terminate on hair cells and primary afferent fibers in the semicircular canals and otolith organs within the inner ear. The function of this efferent vestibular system (EVS) in vestibular and motor coordination though, has pr...
متن کاملEfferent-mediated responses in vestibular nerve afferents of the alert macaque.
The peripheral vestibular organs have long been known to receive a bilateral efferent innervation from the brain stem. However, the functional role of the efferent vestibular system has remained elusive. In this study, we investigated efferent-mediated responses in vestibular afferents of alert behaving primates (macaque monkey). We found that efferent-mediated rotational responses could be obt...
