Saccadic eye movements towards stimuli triggered by prior saccades.
The beginning of a saccade triggers a step in target position. and then the target is estinguished I-300 msec later. A primary saccade follows with normal accuracy. and approximately normal latency. A corrective saccade to the invisible target is possible if the target is lit during the early part of the prior primary saccade. Clearly, important visual stimulation can occur during saccades. and...
متن کاملThe effect of blinks and saccadic eye movements on visual reaction times.
Vision is suppressed during blinks and saccadic eye movements. We hypothesized that visual reaction times (RTs) in a vigilance test would be significantly increased when a blink or a saccade happened to coincide with the stimulus onset. Thirty healthy volunteers each performed a visual RT test for 15 min while their eye and eyelid movements were monitored by a system of infrared reflectance ocu...
متن کاملSaccadic eye movements and cognition.
Scanning of the visual scene is an important selective process in visual perception. In this article we argue that eye-movement data provide an excellent on-line indication of the cognitive processes underlying visual search and reading. We outline some recent advances from physiological investigations of saccadic eye-movement control before focusing on eye-movement behaviour in visual search a...
متن کاملFundamental Research on EEG signals related to free-movements and cued-movement in saccadic eye movements and finger movements
We recorded saccade-related EEG signals and finger-movement related EEG signals in free-movements and cued-movements to found intention of saccadic eye movements. As, results, we found difference components between -500 [ms] to 0 [ms].
متن کاملSaccadic Eye Movement Latencies to Multimodal Stimuli
The saccadic latencies to multimodal stimuli of 10 subjects were studied to determine the range of intersubject variations and to derive values which are representative of the normal population. Responses to simple step and pulse-step stimuli were measured where the target mode and pulse width were randomized. A matrix notation was introduced to describe all of the relevant latency variables wi...
