Frontiers in Human Neuroscience, 2016 Perception of our visual environment strongly depends on saccadic eye movements, which in turn are calibrated by saccadic adaptation mechanisms elicited by systematic movement errors. Current models of saccadic adaptation assume that visual error signals

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

SWIFT: a dynamical model of saccade generation during reading.
Psychology Review, 2005 Mathematical models have become an important tool for understanding the control of eye movements during reading. Main goals of the development of the SWIFT model (R. Engbert, A. Longtin, & R. Kliegl, 2002) were to investigate the possibility of spatially

PLoS ONE, 2019 The anti-saccade task is a commonly used method of assessing individual differences in cognitive control. It has been shown that a number of clinical disorders are characterised by increased anti-saccade cost.

Adaptation of saccadic sequences with and without remapping
Frontiers in Human Neuroscience, 2016 It is relatively easy to adapt visually-guided saccades because the visual vector and the saccade vector match. The retinal error at the saccade landing position is compared to the prediction error, based on target location and efference copy.

Saccadic Predictive Vision Model with a Fovea
, 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]
, 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 ...

Salient Distractors Can Induce Saccade Adaptation
Journal of Ophthalmology, 2014 When saccadic eye movements consistently fail to land on their intended target, saccade accuracy is maintained by gradually adapting the movement size of successive saccades. The proposed error signal for saccade adaptation has been based on the distance

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

The Role of the Oculomotor System in Updating Visual-Spatial Working Memory across Saccades. [PDF]
PLoS ONE, 2016 Visual-spatial working memory (VSWM) helps us to maintain and manipulate visual information in the absence of sensory input. It has been proposed that VSWM is an emergent property of the oculomotor system. In the present study we investigated the role of
