Express-saccades of the monkey: Reaction times versus intensity, size, duration, and eccentricity of their targets
Comparison with response latencies of afferent visual neurons suggests that the dependence of the reaction times of express-as well as regular-saccades on the physical parameters of the target is mostly determined by retinal factors.
Express-saccades of the monkey: Effect of daily training on probability of occurrence and reaction time
The results indicate the existence of a fast-operating visuo-to-oculomotor pathway which can be quickly and reversibly modified by daily exercise.
Further observations on the occurrence of express-saccades in the monkey
It appears that for an express-saccade to occur, the process of interruption of previous active fixation must be completed at the time when a new target becomes visible.
Human express saccades: effects of randomization and daily practice
If the fixation point is turned off some time (200 ms) before the target is turned on, the distribution of the saccadic reaction times is bimodal and the proportion of express saccades increases with daily practice and their reaction times decrease slightly.
A neural correlate for the gap effect on saccadic reaction times in monkey.
It is proposed that the activity of fixation cells in the monkey superior colliculus provide a neural correlate of the gap effect, which weakens the powerful state of inhibition which they normally exert upon the saccade generating system, allowing targets to be acquired at shorter reaction times.
Dead zone for express saccades
For small saccades the express way is blocked functionally or does not exist anatomically and their velocity falls above the main sequence as defined by the least square fit of an exponential v=vo(1-exp(-a/ao) to the maximal velocity (v) versus amplitude (a) relationship.
Separate populations of visually guided saccades in humans: reaction times and amplitudes
The results suggest that, in the gap task, most of the naive subjects exhibit at least two clearly separated peaks in the distribution of the saccadic reaction times, which indicates that express saccades almost never overshoot.

The standard displacement-step stimulus often used to produce lateral saccadic eye movements is considered in terms of the effects of its components: termination of stimulation at an initial fixation
Saccade latency and warning signals: Effects of auditory and visual stimulus onset and offset
The results indicated that the interfering effects occur with visual but not auditory stimuli, with saccades but not motor responses, and when the visual warning event occurs either foveally or in the subject’s periphery.

This invention comprises certain analogs of the prostaglandins in which the C-1 carboxylic is replaced by a primary alcohol and the double bond between C-13 and C-14 is replaced by a triple bond.
