    Damage to the monkey superior colliculus (SC) produces deficits in the generation of saccadic eye movements. Recovery of the accuracy of saccades is rapid, but saccadic latency and peak velocity recover slowly or not at all. In the present experiments we revisited the issue of recovery of...

    Ocular pursuit in monkeys, elicited by sinusoidal and triangular (constant velocity) stimuli, was studied before and after lesions of the nucleus of the optic tract (NOT). Before NOT lesions, pursuit gains (eye velocity/target velocity) were close to unity for sinusoidal and constant-velocity...

    Discusses the primate superior colliculus, and observes an experiment designed to test whether prelude activity is related to saccade selection in saccadic eye movements. Use of a cue to specify which of two physically identical visual stimuli is the goal of an impending saccade; Two classes of...

    Cognitive control requires the selection and maintenance of task-relevant stimulus--response associations, or rules. The dorsolateral prefrontal cortex (DLPFC) has been implicated by lesion, functional imaging, and neurophysiological studies to be involved in encoding rules, but the mechanisms...

    Saccade characteristics in response to moving and stationary targets were studied in three monkeys (Macaca mulatta) that had been trained to look at a target, which after an initial jump either remained in place or moved forward or backward with constant velocity (10°/s). Eye movements were...

    In patients with visual hemifield defects residual visual functions may be present, a phenomenon called blindsight. The superior colliculus (SC) is part of the spared pathway that is considered to be responsible for this phenomenon. Given that the SC processes input from different modalities and...

    The activity of neurons located in the deep intermediate and adjacent deep layers (hereafter called just deep intermediate layer neurons) of the superior colliculus (SC) in monkeys was recorded during saccades interrupted by electrical stimulation of the brainstem omnipause neuron (OPN) region....

    Visuomotor pathways in the vertebrate midbrain mediate rapid, reflexive orienting to abrupt changes. Using the 'inhibition of return' (IOR) mechanism, the attentional system favors novel spatial locations by inhibiting already scanned ones. In a rare patient with a unilateral lesion restricted...

    Of the many functions ascribed to the dorsolateral prefrontal cortex (DLPFC), the ability to override automatic stimulus-driven behavior is one of the most prominent. This ability has been investigated extensively with the antisaccade task, which requires suppression of saccades toward suddenly...

  • Investigating the site of human saccadic adaptation with express and targeting saccades. Hopp, J. Johanna; Fuchs, Albert F. // Experimental Brain Research;Jun2002, Vol. 144 Issue 4, p538 

    To focus on various objects of interest within the visual environment, primates employ rapid eye movements called saccades. When the accuracy of these movements becomes impaired, the brain can adjust their amplitude by a process known as saccadic adaptation. To investigate the locus of this...
