متن کاملReflex suppression in the anti-saccade task is dependent on prestimulus neural processes.
Reflexive responses often must be suppressed to correctly execute a voluntary behavior. It is largely unknown why this control sometimes fails. To examine the neural processes responsible for these failures, we recorded single-neuron activity in the superior colliculus (SC) in behaving monkeys during an anti-saccade task in which they had to suppress a saccade to a visual stimulus that suddenly...
متن کاملOscillatory alpha-band suppression mechanisms during the rapid attentional shifts required to perform an anti-saccade task
Neuroimaging has demonstrated anatomical overlap between covert and overt attention systems, although behavioral and electrophysiological studies have suggested that the two systems do not rely on entirely identical circuits or mechanisms. In a parallel line of research, topographically-specific modulations of alpha-band power (~8-14 Hz) have been consistently correlated with anticipatory state...
متن کاملGiving subjects the eye and showing them the finger: socio-biological cues and saccade generation in the anti-saccade task.
Pointing with the eyes or the finger occurs frequently in social interaction to indicate direction of attention and one's intentions. Research with a voluntary saccade task (where saccade direction is instructed by the colour of a fixation point) suggested that gaze cues automatically activate the oculomotor system, but non-biological cues, like arrows, do not. However, other work has failed to...
متن کاملOptimal performance in a countermanding saccade task.
Countermanding an action is a fundamental form of cognitive control. In a saccade-countermanding task, subjects are instructed that, if a stop signal appears shortly after a target, they are to maintain fixation rather than to make a saccade to the target. In recent years, recordings in the frontal eye fields and superior colliculus of behaving non-human primates have found correlates of such c...
