Dynamic integration of salience and value information for smooth pursuit eye movements

Abstract

We often direct our gaze to the part or object of a scene that appears to be most salient. Visual salience thereby strongly depends on bottom-up features, like relative luminance or color contrast [1]. Pursuit target selection is also known to be influenced by bottom-up features, like stimulus contrast or motion coherence [2,3]. However, topdown factors, like attention [3] or value [4] can also control smooth pursuit. Here we examine the integration of bottom-up salience and top-down value information for the dynamic guidance of smooth pursuit. Introduction
