Human gaze tracks attentional focusing in memorized visual space.

ABSTRACT: Brain areas that control gaze are also recruited for covert shifts of spatial attention^1-9. In the external space of perception, there is a natural ecological link between the control of gaze and spatial attention, as information sampled at covertly attended locations can inform where to look next^2,10,11. Attention can also be directed internally to representations held within the spatial layout of visual working memory^12-16. In such cases, the incentive for using attention to direct gaze disappears, as there are no external targets to scan. Here we investigate whether the oculomotor system of the brain also participates in attention focusing within the internal space of memory. Paradoxically, we reveal this participation through gaze behaviour itself. We d
