Saccadic dysmetria and "intact" smooth pursuit eye movements after bilateral deep cerebellar nuclei lesions.

Author(s) : Büttner, U , Straube, A , Spuler, A
Description : Two patients with well defined lesions of midline cerebellar structures including the fastigial nuclei on both sides presented with saccadic hypermetria but well preserved smooth pursuit eye movements. This is a remarkable finding as the oculomotor vermis (lobules VI, VII) and the fastigial nucleus ...

A model-based theory on the origin of downbeat nystagmus

Author(s) : Marti, S , Straumann, D , Büttner, U , Glasauer, S
Description : The pathomechanism of downbeat nystagmus (DBN), an ocular motor sign typical for vestibulo-cerebellar lesions, remains unclear. Previous hypotheses conjectured various deficits such as an imbalance of central vertical vestibular or smooth pursuit pathways to be causative for the generation of sponta...

Pathological torsional eye deviation during voluntary saccades: a violation of Listing's law.

Author(s) : Helmchen, C , Glasauer, S , Büttner, U
Description : BACKGROUND: Under normal conditions, there are no torsional eye movements during voluntary saccades when the head is stationary (Listing's law). METHODS AND RESULTS: Using dual search coils for three dimensional eye movement recordings, a patient is reported who had direction specific rapid deviatio...

Bilateral loss of eighth nerve function as the only clinical sign of vertebrobasilar dolichoectasia.

Author(s) : Büttner, U , Ott, M , Helmchen, C , Yousry, T
Description : The case of a 55-year-old female is presented, in whom first a loss of the vestibular and hearing function on the left side occurred with sudden onset, and 3 days later an additional loss of functions on the right side occurred. No other neurological symptoms were present. Angiography and MRI scan r...

The effects of baclofen and cholinergic drugs on upbeat and downbeat nystagmus.

Author(s) : Dieterich, M , Straube, A , Brandt, T , Paulus, W , Büttner, U
Description : The GABAergic drug baclofen and the cholinergic drug physostigmine were administered to patients with upbeat and downbeat nystagmus. Baclofen (orally, 5 mg three times daily) reduced nystagmus slow phase velocity and distressing oscillopsia by 25-75% in four out of five patients (two upbeat nystagmu...

Absence of nystagmus during REM sleep in patients with vestibular neuritis

Author(s) : Eisensehr, I , Noachtar, S , Strupp, M , v, L , Brandt, T , Buttner, U
Description : Saccades, including fast phases of nystagmus, disappear during drowsiness and non-rapid eye movement (NREM) sleep, but are present during the alert state and REM sleep. The purpose of this study was to determine whether spontaneous nystagmus is present in patients with vestibular neuritis during REM...

TMS Evidence for Smooth Pursuit Gain Control by the Frontal Eye Fields

Author(s) : Nuding, U , Kalla, R , Muggleton, NG , Buttner, U , Walsh, V , Glasauer, S
Description : Smooth pursuit eye movements are used to continuously track slowly moving visual objects. A peculiar property of the smooth pursuit system is the nonlinear increase in sensitivity to changes in target motion with increasing pursuit velocities. We investigated the role of the frontal eye fields (FEFs...
