Executive control of gaze by the frontal lobes.

Executive control requires controlling the initiation of movements, judging the consequences of actions, and adjusting performance accordingly. We have investigated the role of different areas in the frontal lobe in executive control expressed by macaque monkeys performing a saccade stop signal task. Certain neurons in the frontal eye field respond to visual stimuli, and others control the prod...

Performance monitoring local field potentials in the medial frontal cortex of primates: supplementary eye field.

We describe intracranial local field potentials (LFPs) recorded in the supplementary eye field (SEF) of macaque monkeys performing a saccade countermanding task. The most prominent feature at 90% of the sites was a negative-going polarization evoked by a contralateral visual target. At roughly 50% of sites a negative-going polarization was observed preceding saccades, but in stop signal trials ...

On the origin of event-related potentials indexing covert attentional selection during visual search: timing of selection by macaque frontal eye field and event-related potentials during pop-out search.

Event-related potentials (ERPs) have provided crucial data concerning the time course of psychological processes, but the neural mechanisms producing ERP components remain poorly understood. This study continues a program of research in which we investigated the neural basis of attention-related ERP components by simultaneously recording intracranially and extracranially from macaque monkeys. H...

Conflict in cingulate cortex function between humans and macaque monkeys: More apparent than real.

these and other alternative hypotheses using human subjects. The relative merits of these alternative hypotheses are not the focus of this commentary. Over the last decade this literature derived from human studies has been supplemented by neurophysiological data from macaque monkeys. In monkeys performing an eye movement stop signal task, neurons are found in the supplementary eye field that s...
