Inhibition of return and the human frontal eye fields.

摘要: Inhibition of return (IOR) is a bias against reorienting attention to previously cued location. In this study, using single-pulse transcranial magnetic stimulation (TMS), we show that the human frontal eye fields (FEF) play crucial role in generation IOR. When TMS was applied over right FEF at time interval after visual cue but shortly before target, IOR modulated hemifield ipsilateral such responses target were no longer slower than uncued targets. Control superior parietal lobule, as well had influence on We further involved with selection targets appearing contralateral FEF, not control site, delayed. These results suggest produces by biasing and movements away from attended location facilitating detection novel locations.
