Abstract

Visually guided saccades, memory-contingent saccades, and antisaccades were studied with an infra-red reflection technique in 12 patients with idiopathic blepharospasm and in controls. Latencies of the three kinds of saccades were prolonged. Peak velocities and gains did not differ. Our results indicate an initiation defect in the saccadic system, which may be localized in the caudate nucleus.

摘要

采用红外反射技术对12例特发性眼睑痉挛患者及对照组进行了视觉引导扫视、记忆相关扫视和反扫视的研究。三种扫视的潜伏期均延长。峰值速度和增益无差异。我们的结果表明扫视系统存在启动缺陷，可能定位于尾状核。
