Saccades and drifts differentially modulate neuronal activity in V1: Effects of retinal image motion, position, and extraretinal influences [PDF]

, 2008
In natural vision, continuously changing input is generated by fast saccadic eye movements and slow drifts. We analyzed effects of fixational saccades, voluntary saccades, and drifts on the activity of macaque V1 neurons.

Oculomotor adaptation elicited by intra-saccadic visual stimulation: time-course of efficient visual target perturbation.

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

Visual stimulation of saccades in magnetically tethered Drosophila [PDF]

, 2006
Flying fruit flies, Drosophila melanogaster, perform `body saccades', in which they change heading by about 90° in roughly 70 ms. In free flight, visual expansion can evoke saccades, and saccade-like turns are triggered by similar stimuli in tethered ...

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

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.

Geometry of saccades and saccadic cycles

, 2023
The paper is devoted to the development of the differential geometry of saccades and saccadic cycles. We recall an interpretation of Donder's and Listing's law in terms of the Hopf fibration of the $3$-sphere over the $2$-sphere. In particular, the configuration space of the eye ball (when the head is fixed) is the 2-dimensional hemisphere $S^+_L ...

GIVE me your attention: Differentiating goal identification and goal execution components of the anti-saccade effect.

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.

Voluntary saccade inhibition deficits correlate with extended white-matter cortico-basal atrophy in Huntington's disease

NeuroImage: Clinical, 2017
The ability to inhibit automatic versus voluntary saccade commands in demanding situations can be impaired in neurodegenerative diseases such as Huntington's disease (HD).

Influence of initial fixation position in scene viewing

, 2016
During scene perception our eyes generate complex sequences of fixations. Predictors of fixation locations are bottom-up factors like luminance contrast, top-down factors like viewing instruction, and systematic biases like the tendency to place ...

Atypical disengagement from faces and its modulation by the control of eye fixation in children with Autism Spectrum Disorder [PDF]

, 2011
By using the gap overlap task, we investigated disengagement from faces and objects in children (9–17 years old) with and without autism spectrum disorder (ASD) and its neurophysiological correlates.
