Dissociable roles of dorsolateral prefrontal cortex and frontal eye fields during saccadic eye movements

open access: yesFrontiers in Human Neuroscience, 2015
The dorsolateral prefrontal cortex (DLPFC) and the frontal eye fields (FEF) have both been implicated in the executive control of saccades, yet possible dissociable roles of each region have not been established.

Saccade generation by the frontal eye fields in rhesus monkeys is separable from visual detection and bottom-up attention shift. [PDF]

open access: yesPLoS ONE, 2012
The frontal eye fields (FEF), originally identified as an oculomotor cortex, have also been implicated in perceptual functions, such as constructing a visual saliency map and shifting visual attention.

Saccadic suppression during voluntary versus reactive saccades

open access: yesJournal of Vision, 2017
Saccades are fast eye movements that reorient gaze. They can be performed voluntarily-for example, when viewing a scene-but they can also be triggered in reaction to suddenly appearing targets. The generation of these voluntary and reactive saccades have been shown to involve partially different cortical pathways.

Association of saccade duration and saccade acceleration/deceleration asymmetry during visually guided saccade in schizophrenia patients. [PDF]

open access: yesPLoS ONE, 2014
OBJECTIVE: To examine the difference between schizophrenia patients and normal controls on velocity and acceleration of saccade, by using the basic visually guided saccade (VGS) paradigm.

Incidental threat during visuospatial working memory in adolescent anxiety: an emotional memory-guided saccade task [PDF]

open access: yes, 2015
BackgroundPediatric anxiety disorders are among the most common psychiatric mental illnesses in children and adolescents, and are associated with abnormal cognitive control in emotional, particularly threat, contexts.

Encoding of Intention and Spatial Location in the Posterior Parietal Cortex [PDF]

open access: yes, 1995
The posterior parietal cortex is functionally situated between sensory cortex and motor cortex. The responses of cells in this area are difficult to classify as strictly sensory or motor, since many have both sensory- and movement-related activities, as ...

Detection of stimulus displacements across saccades is capacity-limited and biased in favor of the saccade target

open access: yesFrontiers in Systems Neuroscience, 2015
Retinal image displacements caused by saccadic eye movements are generally unnoticed. Recent theories have proposed that perceptual stability across saccades depends on a local evaluation process centered on the saccade target object rather than on ...

Saccadic Predictive Vision Model with a Fovea

open access: yes, 2018
We propose a model that emulates saccades, the rapid movements of the eye, called the Error Saccade Model, based on the prediction error of the Predictive Vision Model (PVM).

Transcranial direct current stimulation of the frontal eye fields during pro- and antisaccade tasks [PDF]

open access: yes, 2012
Transcranial direct current stimulation (tDCS) has been successfully applied to cortical areas such as the motor cortex and visual cortex. In the present study, we examined whether tDCS can reach and selectively modulate the excitability of the frontal ...

Visual attention is not deployed at the endpoint of averaging saccades.

open access: yesPLoS Biology, 2018
The premotor theory of attention postulates that spatial attention arises from the activation of saccade areas and that the deployment of attention is the consequence of motor programming.
