Visual System: ‘S’ is not for Saccades
Coloured flashes that are visible only to the short-wavelength-sensitive S cones interfere with shifts of visual attention but not with shifts of gaze (saccades). Attention and gaze must therefore be directed by different visual sub-systems.
متن کاملVisual Contrast Processing is Largely Unaltered during Saccades
Saccadic suppression refers to a reduction in visual sensitivity during saccadic eye movements. This reduction is conventionally regarded as mediated by either of two sources. One is a simple passive process of motion smear during saccades also accompanied by visual masking exerted by high-contrast pre- and post-saccadic images. The other is an active process exerted by a neural mechanism that ...
متن کاملVisual continuity across saccades is influenced by expectations.
As we make saccades, the image on each retina is displaced, yet our visual perception is uninterrupted. This is commonly referred to as transsaccadic perceptual stability, but such a description is inadequate. Some visual objects are stable (e.g., rocks) and should be perceived as such across saccades, but other objects may move at any time (e.g., birds). Stability is probabilistic in natural s...
متن کاملExpress saccades and visual attention
One of the most intriguing and controversial observations in oculomotor research in recent years is the phenomenon of express saccades in monkeys and man. These are saccades with such short reaction times (100 msec in man, 70 msec in monkeys) that some experts on eye movements still regard them as artifacts or as anticipatory reactions that do not need any further explanation. On the other hand...
متن کاملRoutine Offered Protocol is not reliable for Thrombophlebitis Prevention
Background: Intravenous catheterization is a routine technique in medical centers which can cause diverse problems such as thrombophlebitis. Objective: This study aimed to resolve replacement scheduling and proper cannula diameter and position issues for intravenous catheters. Methods: In this 2015 experimental cohort study, 232 hos...
