The aim of the present chapter is twofold. First it aims to show that perception requires action. This is most evident for space and action perception. Second, it aims to show that the distinction of the cortical visual processing into two streams is insufficient and leads to possible misunderstandings on the true nature of perceptual processes. I review empirical findings suggesting that visual processing is carried out along three distinct visual pathways qualified as dorso-dorsal, ventro-dorsal, and ventral streams. The relevant anatomical and functional features of the ventro-dorsal stream are presented and discussed.
