Mechanisms of gaze and attention guidance in visual exploration

On average, humans execute over 150,000 saccades each day. Because of the small visual angle subtended by the fovea, exhaustive exploration of the visual surroundings, i.e. complete sampling of the whole visual field, would be much ineffective. Consequently, the decision of where to move the gaze in order to optimize visual information gathering is critical. How the brain achieves this computational conundrum is the central question addressed in the present work.
