    Increased MR signal intensity secondary to chronic cervical cord compression (1987)
    Springer
    Neuroradiology 29 (1987), S. 550-556

    Notes: Summary Magnetic resonance images of 128 patients with compressive lesions of the cervical spinal canal were reviewed to determine whether a high signal intensity lesion within the spinal cord was present on T2 and proton density weighted spin echo images. Such high signal intensity was observed in 24 cases or 18.8%. The incidence was higher in herniated disk (32.4%), atlanto-axial dislocation (28.6%), and ossification of the posterior longitudinal ligament (22.7%), whereas the abnormality was found sporadically in cervical spondylosis and vertebral body tumors. The high intensity lesion on T2 weighted images was generally observed in patients with constriction or narrowing of the spinal cord. The lesion was not demonstrated on T1 weighted spin echo images. Spinal cord constriction or localized narrowing seemed to be the most important portant predisposing factor in producing such a high signal intensity. The pathophysiologic basis of such an abnormality was presumed to be myelomalacia or cord gliosis secondary to a long-standing compressive effect of the spinal cord.

    Focal luxury perfusion with an early-filling vein in relation to neurological symptoms evoked by heat (1985)
    Springer
    Journal of neurology 232 (1985), S. 58-59

    Notes: Summary A 50-year-old man with a 1-year history of transient attacks of left total hemiparesis was admitted to hospital with a complaint of increasing frequency of attacks. Minimal or moderate left hemiparesis was elicited by elevation of environmental temperature when taking a hot bath or a hot shower. Right carotid angiography revealed an early-filling vein near the right central sulcus. An increase of focal luxury perfusion by elevation of body temperature seemed to cause relative ischaemia in this paracentral gyrus.

    Vestibulo-ocular reflex and gaze functions in a patient with congenital inner ear anomalies (1988)
    Springer

    Notes: Summary We report on the vestibulo-ocular reflex (VOR) and gaze functions during horizontal rotations as well as upright locomotions in a fisherman with congenital inner ear anomalies. The finding of a marked gaze disturbance due to low VOR gain during passive rotations resembled that found in early acquired lesions. There was an improvement during active rotations, suggesting an intensified cervicoocular reflex. Although head oscillations in the horizontal plane were abnormally large during stepping and running, they were compensated for visually even at high frequencies. The absence of complaints of oscillopsia as well as his ability to achieve proper balance seemed to be accomplished by his optokinetic ability, regularly transformed head oscillations and modified perceptive mechanisms at higher cortical levels.

    The effect of alcohol on the vestibulo-ocular reflex and gaze regulation (1989)
    Springer
    European archives of oto-rhino-laryngology and head & neck 246 (1989), S. 195-199 
    Details
    ISSN: 1434-4726
    Keywords: Vestibulo-ocular reflex ; Gaze functions ; Smooth pursuit ; Alcohol

    Topics: Medicine
    Notes: Summary To clarify the effect of the temporary decline in cerebellar function on the vestibulo-ocular reflex (VOR) and gaze functions, we examined 12 normal adults under passive rotations before and after they drank alcohol at dosages of 0.43 and 0.65 g/ kg. Whereas spatial gaze fixation was maintained accurately with 0.65 g/kg administration (0.06% blood alcohol level), gaze fixation on a head-fixed target and smooth pursuit were impaired by the higher dosage of 0.43 g/kg (0.03% blood alcohol). The magnitude of the alteration in the VOR gain after drinking was correlated significantly with the VOR gain before drinking: while small values were enhanced by drinking, large values were suppressed. The present study indicates that the VOR in the dark is regulated by the balance between the amplifying and suppressing forces controlled by the cerebellum.
