Effect of Mo and W underlayers on ordered phase formation in Fe-Au-Pd multilayer thin films at low temperatures.

Fe-Pd based thin films with Au intermediate layer fabricated on different substrates (SiO, SiO/Mo, SiO/W) were investigated at annealing temperatures up to 460 °C. The samples were deposited by magnetron sputtering and were post-annealed in vacuum. The ongoing processes were investigated by chemical depth profiling and X-ray diffraction.

Quantitative analysis of motor performance in epilepsy patients treated with valproate.

Purpose: The aim of our study was to detect objective signs of deterioration of motor performance in epilepsy patients treated with chronic valproate therapy.

Methods: We examined 14 controls and 15 epilepsy patients receiving chronic valproate monotherapy, who had no subjective complaints related to motor function. Regularity and maximum frequency of repetitive hand and finger movements, and simple reaction time were measured.

Post-movement beta synchronisation after complex prosaccade task.

Objective: Post-movement beta synchronisation (PMBS) has been described as an induced, localised increase of beta activity over the contralateral sensorimotor cortex after termination of voluntary limb movement. The aim of our study was to investigate whether ocular saccades also evoke movement related EEG changes.

Methods: Complex saccades were recorded in six healthy volunteers using electro-oculography.

One-and-a-half syndrome--two cases.

One-and-a-half syndrome is characterized by combination of the clinical features of unilateral horizontal gaze palsy and internuclear ophthalmoplegia. The common symptoms are double vision and oscillopsia. The lesion is located in the paramedian pontine reticular formation, involving the centre of horizontal gaze and medial longitudinal fasciculus.

EEG correlates of subcortical optokinetic nystagmus.

Objective: Our aim was to reveal the changes of concomitant scalp EEG activity during subcortical (stare-) optokinetic nystagmus (OKN).

Methods: Stare-OKN of 10 subjects was evoked and recorded simultaneously with the EEG. Frequency distribution of OKN-beats was determined in each subject.

[Complex eye movement disturbance in thalamic and mesencephalic infarcts].

A 36 year-old male patient developed sudden double vision and gait imbalance. Neurological examination revealed gaze paresis upward and on the left side downward (vertical "one-and-a-half"-syndrome), horizontal gaze nystagmus on the left bulbus directed to left. The MRI revealed bilateral thalamic and left midbrain ischemic lesions.
