Abstract
Humans make frequent movements of the eyes (saccades) to explore the visual environment. Here, we argue that visuospatial working memory (VSWM) is a fundamental component of the eye movement system. Memory representations in VSWM are functionally integrated at all stages of orienting: (a) selection of the target; (b) maintenance of visual features across the saccade; (c) the computation of object correspondence after the saccade, supporting the experience of perceptual continuity; and (d) the correction of gaze when the eyes fail to land on the intended object. VSWM is finely tuned to meet the challenges of active vision.
