BACKGROUND Most people show a remarkable deficit to report the second of two targets when presented in close temporal succession, reflecting an attentional restriction known as the 'attentional blink' (AB). However, there are large individual differences in the magnitude of the effect, with some people showing no such attentional restrictions. METHODOLOGY/PRINCIPAL FINDINGS Here we present be...
Previous studies have suggested that abnormal visual experience early in life induces ocular motor abnormalities. The purpose of this study was to determine how visual deprivation alters the function and gene expression profile of the ocular motor system in mice. We measured the effect of dark rearing on eye movements, gene expression in the oculomotor nucleus, and contractility of isolated ext...
Patients affected with multiple sclerosis (MS) frequently suffer from vestibular disorders due to vestibulospinal involvement. The vestibulospinal reflexes in these subjects can be well investigated through vestibular evoked myogenic potentials (VEMPs). Evoked by the acoustic stimulation of the saccular macula and mediated by the vestibulocollic reflex pathway, they are recorded using surface e...
INTRODUCTION Controversies arise with respect to functioning of the middle ear over time. OBJECTIVE To assess changes in middle ear impedance that may be related to aging, and/or if there was an association of these changes with those of the inner ear in the elderly patients. METHODS Cross-sectional, comparative study of elderly patients managed in ear, nose and throat clinics. A structured...
The pathophysiology of obstructive sleep apnoea (OSA) is complex and incompletely understood. A narrowed upper airway is very common among OSA patients, and is usually in adults due to nonspecific factors such as fat deposition in the neck, or abnormal bony morphology of the upper airway. Functional impairment of the upper airway dilating muscles is particularly important in the development of ...
introduction: we aimed to assess whether the vasodilator effect of oral dipyridamole on the left ventricular systolic function in patients with suspected cad is different from that of intravenous (iv) dipyridamole using tc-99m mibi myocardial perfusion gated spect. methods: eighty-nine patients (17 m / 72 w; 61 ± 10 years) were enrolled in this study. the patients underwent a dipyridamole stres...
The cervico-ocular (COR) and active and passive vestibulo-ocular reflexes (VOR) were measured in seven patients with spasmodic torticollis (ST) and six normal controls. The COR was found to be weak or absent in both groups. The VOR gain was similar in the two groups but five patients had a significant asymmetry of the response. There was no evidence of abnormal cervico-vestibular interaction du...
A 25-year-old man, a field operator in a petroleum refinery was found unconscious. He was exposed to hydrogen sulfide and presented with Glasgow Coma Score of 5, severe hypoxemia on arterial blood gas analysis, normal chest radiography, and normal blood pressure. On hospital day 7, his mental state became clear, and neurologic examination showed quadriparesis, profound spasticity, increased ten...
