A “spontaneous” dissecting aneurysm of the petrous portion of the right internal carotid artery in a 60 year old man was demonstrated angiographically. It showed a typical double lumen which is rarely demonstrated by angiography. It was probably of atherosclerotic origin. In addition, a survey of the positions and angiographic characteristics of the 29(More)
Extraocular motor unit activity was recorded electromyographically from the lateral and medial rectus muscles in eight normal subjects, together with their EOGs. Twelve motor units showed a discharge pattern characterized by regular firing during positions of fixation, a burst of saccadic "on" activity and complete silence during saccades in the "off"(More)
Interval analyses of denervation potentials (fibrillation-potentials and positive sharp waves) in human skeletal muscles were performed using a DEC PDP-12 computer. Extremely small differences between consecutive intervals (usually less than 1%) and slow up and down drifts in the spontaneous discharge frequency were found to be characteristic of repetitive(More)
Three instances of spontaneous recanalization of internal carotid artery occlusion are presented. In the first, extensive extra- and intracranial lesions including severe stenoses and prestenotic aneurysmatic dilatation were demonstrated by angiography. Gradual disappearance of these alterations was shown by control angiograms. In the second and third(More)
Angiographic and/or operative follow up studies on 19 patients with angiographically demonstrated subtotal carotid artery stenosis showed the following results: In 3 out of 16 cases where no immediate operation of the stenosis was performed, complete occlusion followed within a week of the angiographic demonstration of the stenosis. Though intramural(More)
