Knowing the future: partial foreknowledge effects on the programming of prosaccades and antisaccades [PDF]
, 2011 Foreknowledge about the demands of an upcoming trial may be exploited to optimize behavioural responses. In the current study we systematically investigated the benefits of partial foreknowledge--that is, when some but not all aspects of a future trial ...

Psychophysical Investigation of Cognitive Processes behind Oculomotor Deficits associated with Traumatic Brain Injury [PDF]
, 2020 Purpose: People with Traumatic brain injury (TBI) manifest deficits in oculomotor functions such as antisaccades and memory-guided prosaccades. Generation of these voluntary saccades are influenced by high-level cognitive processes.

The Effects of Individual Differences on Cued Antisaccade Performance
Journal of Eye Movement Research, 2008 In the antisaccade task, pre-cueing the location of a correct response has the paradoxical effect of increasing errors. It has been suggested that this effect occurs because participants adopt an "antisaccade task set" and treat the cue as if was a ...

Saccadic dysfunction in patients with hypoxic-ischemic encephalopathy [PDF]
Journal of Integrative Neuroscience, 2018 Electrophysiological monitoring of saccadic eye movements in patients with hypoxic-ischemic encephalopathy was carried out. Externally guided saccades (prosaccades) were recorded using a patented hardware-software complex for studying a subject's ...

Cortical Sources of ERP in Prosaccade and Antisaccade Eye Movements using Realistic Source Models
Frontiers in Systems Neuroscience, 2013 The cortical sources of event-related-potentials (ERP) using realistic source models were examined in a prosaccade and antisaccade task. College-age participants were presented with a preparatory interval and a target that indicated the direction of the ...

Strategic modulation of the fixation-offset effect: dissociable effects of target probability on prosaccades and antisaccades [PDF]
, 2005 In several previous experiments examining the effects of participants’ expectations on oculomotor performance, the manipulation of target probability has been confounded with factors such as target occurrence and saccade frequency. We report results from

Eye Gaze and Aging: Selective and Combined Effects of Working Memory and Inhibitory Control
Frontiers in Human Neuroscience, 2017 Eye-tracking is increasingly studied as a cognitive and biological marker for the early signs of neuropsychological and psychiatric disorders. However, in order to make further progress, a more comprehensive understanding of the age-related effects on ...

A Single Bout of Intermittent Hypoxia Increases Cerebral Blood Flow and Supports an Executive Function Benefit. [PDF]
PsychophysiologyABSTRACT Alternating between brief normoxic and hypoxic intervals (i.e., intermittent hypoxia: IH) increases cerebrovascular dilation, cerebral blood flow (CBF), and O2 extraction. Some work has shown that the physiological adaptations arising from multiple IH sessions improve brain health and executive function (EF)—a finding linked to a post ...

Educational and Cognitive Predictors of Pro- and Antisaccadic Performance
Frontiers in Psychology, 2017 Voluntary gaze control allows people to direct their attention toward selected targets while avoiding distractors. Failure in this ability could be related to dysfunctions in the neural circuits underlying executive functions.
