This chapter discusses the space representations in the mammalian brain. It describes the rigid motions and scale changes that are representative of affine transformations of space. It shows the mathematical ideas of maps and charts that have become increasingly relevant to describe the pattern of neural activities in the hippocampus. It also addresses the neural mechanism that leads to the formation of space cells in the hippocampus. This chapter shows the function implemented by the grid cells in the entorhinal cortex, and their relation to the function implemented by the place cells in the hippocampus. It suggests how brain activities evolve between entorhinal cortex and hippocampus.

Keywords:   space representations, mammalian brain, maps, charts, hippocampus, grid cells, entorhinal cortex, space cells
