  1. 1. Central vestibular compensation : the role of the GABAB receptor

    Författare :Anna Magnusson; Ulrich Büttner; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The remarkable capacity for adaptive plastic changes in response to changed internal or external conditions is a distinctive feature of the vestibular system. Even in adults the system can be modified throughout life due to altered conditions caused by disease. trauma, medical treatment or normal ageing. LÄS MER

  3. 2. Visual influences on vestibular compensation and postural control

    Författare :Anna Hafström; Lund näs- och halssjukdomar Öron-; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; audiology; auditive system and speech; Otorinolaryngologi; Medicin människa och djur ; Vestibular schwannoma; Alcohol intoxication.; Medicine human and vertebrates ; Vestibular deafferentation; Visual-vestibular interactions; Subjective visual horizontal and vertical; Visual dependence; Utriculus; Balance; Vision; audiologi; hörsel- och talorganen;

    Sammanfattning : This thesis aimed to investigate visual-vestibular interactions in healthy subjects and in patients with a well defined unilateral vestibular lesion (vestibular schwannoma before and six months after translabyrinthine surgery). Visual information is particularly important for balance control during perturbed stance. LÄS MER

  4. 3. Vestibular control of body orientation in lamprey

    Författare :Elena Pavlova; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Postural control; orientation; vision; vestibular system; visuo-vestibular interaction; vestibular compensation; locomotion; supraspinal control; lamprey;

    Sammanfattning : Maintenance of body orientation (postural control) is a vital motor function of the brain. The general goal of this project was to understand the organization and operation of neuronal networks responsible for postural control. The lamprey (a lower vertebrate) was used as a model animal.

  5. 4. The subjective visual horizontal in the diagnosis of vestibular disorders : physiological and clinical considerations

    Författare :Arne Tribukait; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Vestibular system; vestibular tests; vestibular neuritis; Meniere sdisease; gentamicin treatment; vestibular compensation; stapedotomy; spatial orientation; gravity otoliths; utricle; saccule; semicircular canals; subjective visual horizontal; roll;

    Sammanfattning : In the examination of patients with vestibular disturbances the diagnostic techniques are almost entirely focused on the semicircular canals. However, a considerable number of the patients have symptoms which are suggestive of an affection of the otolith organs, e.g. false sensations of tilt or linear motion and even sudden falls. LÄS MER

  7. 5. Ocular counter-rolling during head tilt

    Författare :Tony Pansell; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Eye movements; Ocular torsion; VOR; head tilt; Vision.;

    Sammanfattning : When tilting the head towards the shoulder there are numerous mechanisms influencing on the generation and maintenance of ocular counter-roll. Each of these mechanisms has its own temporal and spatial characteristics which influences on the counter-rolled eye position. LÄS MER
