Instructing participants to “identify a target” dramatically reduces saccadic reaction times in prosaccade tasks (PS). However, it has been recently shown that this effect disappears in antisaccade tasks (AS). The instruction effect observed in PS may result from top-down processes, mediated by pathways connecting the prefrontal cortex (PFC) to the superior colliculus. In AS, the PFC's prior involvement is in competition with the instruction process, annulling its effect. This study aims to… 

What saccadic eye movements tell us about TMS-induced neuromodulation of the DLPFC and mood changes: a pilot study in bipolar disorders

The antisaccade (AS) task could be a relevant and useful tool for clinicians to assess if the Transcranial magnetic stimulation (TMS)-induced short-term neuromodulation of the DLPFC occurs as a “trait vs. state” objective marker of depressive mood disorder.

The Influence of Attention and Target Identification on Saccadic Eye Movements Depends on Prior Target Location

Together, anticipatory error data and saccade latency interactions suggest a source of ISR at a higher level of attention, possibly localised in the dorsolateral prefrontal cortex and involving tonic activation.

Mixed saccadic paradigm releases top-down emotional interference in antisaccade and prosaccade trials

It is demonstrated that prosaccades latencies are significantly reduced by emotion, while antisaccades are significantly increased, suggesting a disinhibition of reflexive saccades.



Having to identify a target reduces latencies in prosaccades but not in antisaccades

The present study tests if the task instruction also reduces the latencies of antisaccades (AS), which involve prefrontal structures, and shows that instruction reduces latencies for prosaccade but not for AS.

When does the brain inform the eyes whether and where to move? An EEG study in humans.

The current study addressed when in the course of stimulus processing, and in what brain areas, activity occurs that supports the interpretation of cues that signal the appropriateness of different and competing behaviors to highlight how a distributed neural architecture supports the evaluation of stimuli and response choices.

Neuronal substrate of the saccadic inhibition deficit in schizophrenia investigated with 3-dimensional event-related functional magnetic resonance imaging.

A frontostriatal network is engaged in the suppression of automatic eye movements and the results indicate that abnormalities in this network, rather than the selective dysfunction of prefrontal brain regions, underlie the saccade inhibition deficit in schizophrenia.

Look away: the anti-saccade task and the voluntary control of eye movement

Recent neurophysiological evidence is described demonstrating the presence of this inhibitory function in single-cell activity in the frontal eye fields and superior colliculus in patients diagnosed with various neurological and/or psychiatric disorders that affect the frontal lobes or basal ganglia.

Preparatory set associated with pro-saccades and anti-saccades in humans investigated with event-related FMRI.

This finding suggests that the increased cortical activation found in previous blocked designs originates predominately from Differences in preparatory set and not from differences in the motor signal between pro- and anti-saccades.

Localization of Executive Functions in Dual-Task Performance with fMRI

The results support the conclusion that dorsolateral prefrontal and superior parietal cortices are involved in the coordination of concurrent and interfering task processing.

Control of sensorimotor variability by consequences.

The results demonstrate that learned contingencies can affect reaction time variability and support the view that the so-called noise level in decision processes can undergo long-term changes.

Verbal Working Memory Load Affects Regional Brain Activation as Measured by PET

The data support a model of working memory that includes both storage and executive processes that recruit a network of brain areas, all of which are involved in task performance.
