Because real-world scenes typically contain many different potential objects of interest, selecting one goal from many is clearly a fundamental problem faced by the saccadic system. We recorded from visual, movement, and visuo-movement (VM) neurons in the superior colliculus (SC) of monkeys performing a reaction-time visual-search task requiring them to make saccades to an odd-colored target presented with distractors. First, we compared the responses of SC neurons in search with their… 
Neuronal activity in superior colliculus signals both stimulus identity and saccade goals during visual conjunction search.
TLDR
The findings show that the outcome of all visual search trials, regardless of the stimulus being selected, is predicted by SC neuronal activity, suggesting that visual stimuli are selected when these neurons reach a critical activation level.
Predictive Saccade Target Selection in Superior Colliculus during Visual Search
TLDR
How neural representations on the visual salience map are processed in parallel are demonstrated in parallel, thus facilitating visual search, as shown in monkeys trained to perform a multiple-fixation visual conjunction search task.
Frontal eye field activity before visual search errors reveals the integration of bottom-up and top-down salience.
TLDR
The results suggest that FEF serves as a saccade probability map derived from the combination of bottom-up and top-down influences, which may correspond to the theoretical salience map of many models of attention and saccades target selection.
Deficits in saccade target selection after inactivation of superior colliculus
TLDR
The results indicate that the superior colliculus has an important functional role in target selection, in addition to its well-established involvement in movement execution, the SC.
Short-term priming, concurrent processing, and saccade curvature during a target selection task in the monkey
TLDR
It is found that monkeys show the influence of a cumulative, short-term priming mechanism which facilitates saccades when the color of the search target happens to repeat from trial to trial, and when monkeys make such two-saccade responses, the trajectory of the initial saccade tends to curve toward the goal of the subsequent saccADE.
Saccade target selection in unconstrained visual search
Our visual system is regularly faced with more information than it can process at once. As a result, our visual experience generally arises from the sequential sampling of visual details by overtly
Eye-hand coordination during target selection in a pop-out visual search.
TLDR
The coordination of saccades and reaches in a visual search task in which monkeys were rewarded for reaching to an odd-colored target among distractors is examined, consistent with flexible temporal coupling of sAccade and reach initiation, but fairly tight coupling of target selection for the two types of action.
Separate Visual Signals for Saccade Initiation during Target Selection in the Primate Superior Colliculus
TLDR
Results suggest that separate mechanisms may independently influence the saccadic command in the SC, one linked to the arrival time of pertinent visual signals, and another linked toThe output of the visual selection process.
Predictive activity in macaque frontal eye field neurons during natural scene searching.
TLDR
Findings suggest that during natural visual search the timing of FEF cell activity is consistent with a role in specifying targets for one or more future saccades in a search sequence.
Saccade target selection in visual search: accuracy improves when more distractors are present.
TLDR
The results are related to a general framework whereby the presence of distractors operates to hold fixation for a longer period of time, thus allowing a greater period of visual processing and more accurate eye movements.

Target selection for saccadic eye movements: direction-selective visual responses in the superior colliculus.
TLDR
The results indicate that a small population of SC prelude neurons exhibits properties appropriate for linking stimulus cues to saccade target selection in the context of a visual discrimination task.
Short-term priming, concurrent processing, and saccade curvature during a target selection task in the monkey
TLDR
It is found that monkeys show the influence of a cumulative, short-term priming mechanism which facilitates saccades when the color of the search target happens to repeat from trial to trial, and when monkeys make such two-saccade responses, the trajectory of the initial saccade tends to curve toward the goal of the subsequent saccADE.
Superior colliculus activity related to concurrent processing of saccade goals in a visual search task.
TLDR
The results indicate that, at the time of an initial saccade, the SC does not necessarily act as a strict winner-take-all network and it appears that the salience of a second visual goal can be simultaneously maintained in the SC.
Modulation of Neuronal Activity in Superior Colliculus by Changes in Target Probability
TLDR
It is found that the activity of monkey superior colliculus (SC) neurons was predictive of the latency of a saccadic eye movement and not other saccade parameters such as end point or peak velocity.

TLDR
The results suggest that the PF cortex may be involved in the decision-making process and the focal attention for saccade target selection.
Target selection for saccadic eye movements: prelude activity in the superior colliculus during a direction-discrimination task.
TLDR
Results are consistent with the notion that a restricted network of SC neurons plays a role in the process of saccade target selection, and are particularly strong in a subpopulation of neurons with directional visual responses that have been described previously.
Collicular involvement in a saccadic colour discrimination task
TLDR
The neural activity of single superior colliculus (SC) neurons in monkeys engaged in a saccadic target/nontarget discrimination task based on a colour cue suggests the possibility that the decision as to which saccade should be made was largely imposed upon the SC visuomotor cells by an external source.
Movement selection in advance of action in the superior colliculus
TLDR
The results suggest that the superior colliculus participates in the process of saccade selection, and shows that prelude activity occurs shortly after information is available for correct saccades selection and, more importantly, the activity is predictive of sAccade choice.
Neural basis of saccade target selection in frontal eye field during visual search
TLDR
This work investigated target selection in rhesus monkeys performing a visual search task by recording neurons in the frontal eye field, an area known to be responsible for generating purposive eye movements, and found that the initial visual responses to search stimulus arrays were the same whether the target or a distraction was in the response field.
Dissociation of visual and saccade-related responses in superior colliculus neurons.
TLDR
It is concluded that the presumed linkage, implied in earlier versions of the foveation hypothesis, between the superficial layers (receiving direct retinal inputs) and the deeper layers of the SC is not necessary for the activation of SR neurons.
