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 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 کاملCholinergic mechanisms in depression.
Evidence supporting a cholinergic hypothesis of depression is presented. First, cholinergic overdrive produces behavioral, neuroendocrine, and polysomnographic features of melancholia, and melancholics exhibit state-independent supersensitivity to cholinergic overdrive. Drugs inducing up-regulation and supersensitivity of cholinergic systems produce behavioral, polysomnographic, and neuroendocr...
متن کاملAcoustically responsive fibers in the vestibular nerve of the cat.
Recordings were made from single afferent fibers in the inferior vestibular nerve, which innervates the saccule and posterior semicircular canal. A substantial portion of the fibers with irregular background activity increased their firing in response to moderately intense clicks and tones. In responsive fibers, acoustic clicks evoked action potentials with minimum latencies of < or = 1.0 msec....
متن کاملQuantitative histochemical mapping of enzymes of the cholinergic system in cat cochlear nucleus.
Activities of choline acetyltransferase and acetyicholinesterase were measured in samples dissected from freeze-dried sections of cat cochlear nuclei and the immediate surroundings. Refined methods of sampling and record-keeping were systematically applied at the histologic level. Selected sections were studied for nine cochlear nuclei, and a more complete threedimensional map of enzyme distrib...
