When a temporal gap is introduced between the extinction of a central fixation target and the illumination of an eccentric target (the gap paradigm), normal human subjects initiate saccadic eye movements towards the eccentric target at lower latency than when there is no gap. The aim of this study was to examine the latency of human smooth pursuit eye movements using a modified gap paradigm. Smooth pursuit latency was reduced in gap tasks, and the magnitude of reduction was related to the duration of the gap. The distribution of smooth pursuit latencies was also altered. It thus appears that human smooth pursuit latency is modulated in a similar manner to saccade latency in gap tasks.
当在中央注视目标消失与偏心目标照明之间引入时间间隔(间隙范式)时,正常人类受试者向偏心目标发起扫视眼动的潜伏期比无间隙时要短。本研究的目的是使用改良的间隙范式来检查人类平稳跟踪眼动的潜伏期。在间隙任务中,平稳跟踪潜伏期缩短,缩短幅度与间隙持续时间有关。平稳跟踪潜伏期的分布也发生了改变。因此,在间隙任务中,人类平稳跟踪潜伏期似乎与扫视潜伏期以类似方式受到调制。
