Abstract
Five healthy subjects were submitted to sinusoidal lateral tilt (amplitude 25° at frequency of 0.2Hz) of the whole body, only the head, or only the trunk about a vertical (subject in upright position) and about a horizontal axis (subject in supine position). The ocular torsioation of the neck by manipulating only the trunk had a negligible effect on ocular torsion. The cervical contribution to OT was best visible as the difference between the ocular torsion signals obtained in conditions of head tilt and conditions with whole body tilt. Apparently stimulation of the semicircular canals facilitates the cervically induced ocular torsion. Contribution of the neck did not affect the slow component, but produced an anticompen-satory modulation of the beating field offset (analogous to gaze shift). As a result, the excursion range of torsional eye position was smaller during head tilt than during body tilt. Static tilt conditions (25° tilt) of only the trunk, only the head or of the whole body showed similar data, although of smaller amplitude.
Met video-oculografie werd oogtorsie gemeten tijdens kanteling van het hele lichaam, alleen het hoofd en alleen de romp. Gevonden werd dat de cervikale bijdrage aan de oogtorsie tot doel heeft om de vestibulaire compensatoire oogtorsie tijdens actieve hoofdbewegingen tegen te gaan.
