Building a Space Map
Building a Space Map
This chapter reviews the computational problems that the brain must solve for creating and maintaining a representation of the extrapersonal space. It specifically addresses the simplified model of a gerbil, with a single one-dimensional “eye,” moving over a two-dimensional plane. It introduces the general issues encountered in forming and maintaining a space map. This chapter shows that the map of space built during navigation by combining the process and the observation models defines a spatial domain that offers a support for storing and retrieving memories of rewarding events, such as the discovery of food, as well as of adverse and dangerous situations.
Keywords: space map, computational problems, gerbil, eye, navigation, extrapersonal space
