Electro-oculographic study of saccadic pursuit eye movements in patients with brain lesions

摘要: Abstract Electrooculograms were recorded in 36 patients with either left or right hemisphere lesions and 20 normal adults during eye movements on command, slow pursuit induced optokinetic nystagmus (OKN). In all the command produced electrooculograms similar to those of subjects, a fast one-step movement. Saccadic constant finding cases posterior hemispheric lesions, but they exceptionally normals. They more numerous when lesion was located hemisphere. Unidirectional saccadic most frequently recorded, particularly following right. Bidirectional eyes saccades rare, combination uni- bi-directional (mixed type) commonly seen. potentials usually both directions; rarely one direction only. The always related moving target. horizontal OKN asymmetric 29 symmetric 7 cases. group, cases, eception one, showed pursuit. Of response 5 2 smooth following. When present an abnormal side contralateral lesion. normals symmetric. relationships are discussed reference brain localization lesions.
