Post-saccadic changes disrupt attended pre-saccadic object memory
Journal of Vision, 2021 Trans-saccadic memory consists of keeping track of objects' locations and features across saccades; pre-saccadic information is remembered and compared with post-saccadic information. It has been shown to have limited resources and involve attention with respect to the selection of objects and features.

Frontiers in Human Neuroscience, 2011 Gap and overlap tasks are widely used to promote automatic versus controlled saccades. This study examines the hypothesis that the right posterior parietal cortex (PPC) is differently involved in the two tasks. Twelve healthy students participated in the

Vision Research, 2010 Our actions need constant calibration to arrive accurately at locations of their intended goals; errors in execution must drive rapid adjustments. As an example, saccadic eye movements are vital for bringing objects of interest into the high-acuity center of vision and they must be continually tuned to compensate for ongoing changes in body, muscle ...

Voluntary Spatial Attention has Different Effects on Voluntary and Reflexive Saccades
The Scientific World Journal, 2003 Although numerous studies have investigated the relationship between saccadic eye movements and spatial attention, one fundamental issue remains controversial.

Pre-saccadic perception: separate time courses for enhancement and spatial pooling at the saccade target [PDF]
, 2017 We interact with complex scenes using eye movements to select targets of interest. Studies have shown that the future target of a saccadic eye movement is processed differently by the visual system.

Monetary reward speeds up voluntary conditional saccades
Frontiers in Integrative Neuroscience, 2014 Past studies have shown that reward contingency is critical for sensorimotor learning, and reward expectation speeds up saccades in animals. Whether monetary reward speeds up saccades in human remains unknown.

The antisaccade task as an index of sustained goal activation in working memory: modulation by nicotine [PDF]
, 2006 The antisaccade task provides a laboratory analogue of situations in which execution of the correct behavioural response requires the suppression of a more prepotent or habitual response.

The influence of visual landscape on the free flight behavior of the fruit fly Drosophila melanogaster [PDF]
, 2002 To study the visual cues that control steering behavior in the fruit fly Drosophila melanogaster, we reconstructed three-dimensional trajectories from images taken by stereo infrared video cameras during free flight within structured visual landscapes ...

Journal of Neuroscience, 2000 Diversity in behavioral responses to sensory stimuli has been attributed to variations in preparatory set. Variability in oculomotor responses toward identical visual stimuli has been well documented, but the neuronal processes underlying this ...

Slowed vertical saccades as a hallmark of hereditary spastic paraplegia type 7
Annals of Clinical and Translational Neurology, 2019 Anecdotal oculomotor disturbances have been described in spastic paraplegia type 7 (SPG7). We investigated oculomotor and vestibular dysfunction in five patients with genetically verified SPG7.
