文摘
- •
We studied the neural mechanisms of competition processes in the antisaccade task.
- •
Competition models assume that infrequency slows saccade programming.
- •
Latencies and errors of anti- and prosaccades increased with reduced frequency.
- •
Systematically slowed saccades showed BOLD signal changes in the saccade network.
- •
Context dependent mechanisms coordinate decision signals to facilitate gaze control.
