Cortical sources of event-related potentials in the prosaccade and antisaccade task
- Psychophysiology
, 2003
"... The cortical sources of event-related potentials (ERP) were examined in a prosaccade and antisaccade task in college-age participants. The task included a cue that indicated the spatial location of the target, a cue that indicated the type of eye movement, or no cue. A principal component analysis a ..."

Role of primate superior colliculus in preparation and execution of anti-saccades and prosaccades.
- J Neurosci
, 1999
"... We investigated how the brain switches between the preparation of a movement where a stimulus is the target of the movement, and a movement where a stimulus serves as a landmark for an instructed movement elsewhere. Monkeys were trained on a pro-/anti-saccade paradigm in which they either had to ge ..."

to generate a pro-saccade toward a visual stimulus or an anti-saccade away from the stimulus to its mirror position, depending on the color of an initial fixation point. Neural activity was recorded in the superior colliculus (SC), a structure that is known to be involved in the generation of fast saccades
Cortical Dynamics during the Preparation of Antisaccadic and Prosaccadic Eye Movements in Humans in a Gap Paradigm
"... To compare the cortical dynamics of different oculomotor tasks, EEG and eye movements were recorded in 21 volunteers. Using a comprehensive approach, subjects were asked to perform saccadic tasks, which included a saccadic eye movement to a peripheral target (prosaccadic), a movement to the opposite ..."

to the opposite side (antisaccadic), or maintain the gaze fixed (no-go). In mixed trials, prosaccadic, antisaccadic and no-go tasks were indicated by a color square (S1) present for 1900–2500 ms (instructive period). S1 disappeared for 370 ms (gap) and a black dot at 8 deg at right or left indicated the beginning
and prosaccade errors in schizophrenia
, 2006
"... Abstract Whether antisaccade errors in schizophrenia are due to defects in implementing saccadic inhibition or diY-culty in generating novel responses is uncertain. We inves-tigated whether antisaccade errors were related to diYculty in inhibiting saccades when subjects were asked to main-tain stead ..."

in the preparatory period of saccadic trials, but not with the frequency of Wxation losses during Wxation trials. Third, antisaccade errors were more likely to occur in trials with unstable Wxation than in trials with stable Wxation. Last, antisaccade error rate was also correlated with prosac-cade error rate. We
DP (2000) Neuronal correlates for preparatory set associatedwith pro-saccades and anti-saccades in the primate frontal eye field
- J Neurosci
"... Diversity in behavioral responses to sensory stimuli has been attributed to variations in preparatory set. Variability in oculo-motor responses toward identical visual stimuli has been well documented, but the neuronal processes underlying this vari-ability are poorly understood. Here, we report evi ..."

evidence for set-related activity for saccadic eye movements in single neu-rons in the frontal eye field (FEF) in monkeys trained on a task in which they either had to look toward a visual stimulus (pro-saccade) or away from the stimulus (anti-saccade) depending on a previous instruction. A portion of FEF
PSYCHOBIOLOGY AND BEHAVIORAL STRATEGIES Latency of Prosaccades and Antisaccades in Professional Shooters
"... time in professional clay-target shooters found in a previous study was because of a superiority of athletes arising at the attention level or at level of saccadic motor preparation. Method: Ten shooters with at least 6 yr of shooting training in Olympic shotgun disciplines and 10 control subjects p ..."

In the overlap paradigm, a target was presented randomly at one of four cardinal positions with the fixation point presented throughout the trial

Monkey Prefrontal Cortical Pyramidal and Putative Interneurons Exhibit Differential Patterns of Activity Between Prosaccade and Antisaccade Tasks
"... Previous studies have shown that prefrontal cortex (PFC) neurons carry task-related activity; however, it is largely unknown how this selectivity is implemented in PFC microcircuitry. Here, we exploited known differences in extracellular action potential waveforms, and antidromic identification, to ..."

Putative pyramidal neurons had higher stimulus-related activity on antisaccade trials, whereas putative interneurons exhibited greater activity for prosaccades. These findings suggest that task-selectivity in the PFC may
� Human Brain Mapping 26:119–127(2005) � Functional Interactions Between Oculomotor Regions During Prosaccades and Antisaccades
"... Abstract: Human behavior reflects a continual negotiation of automatic and directed actions. The oculomotor network is a well-characterized neural system in which to study this balance of behavioral control. For instance, saccades made toward and away from a flashed visual stimulus (prosaccades and ..."
