Space perception

Abstract

A key-function of our brain is to process spatial information and make it available to our motor systems to interact with the environment. Spatial information can be derived from vision. But the location of the image of an object shifts across the retina by each eye-movement. So, where exactly in space are objects located? While other sensory signals can provide us also with relevant information, here, we focus on the dominant sense in primates: vision. We illustrate how space representation is probed behaviorally and at the neural level and discuss its relationship to other signals of magnitude: time and number.
