Abstract

Inhibition of return (IOR) is a well-established attentional phenomenon in which responses to targets at previously cued locations are slowed relative to uncued locations. Despite its behavioral characterization, the neural origins of IOR remained unclear. The present study applied transcranial magnetic stimulation (TMS) over the human frontal eye fields (FEF) to examine whether this cortical oculomotor region contributes to IOR. TMS over FEF disrupted the normal expression of IOR, implicating the frontal eye fields as a neural generator of this inhibitory attentional bias. These results bridge oculomotor and attentional control circuits in the production of spatial IOR.
