English: Schematic illustration of the components of the dorsal (blue) and ventral (orange) attention system in the human brain. Whereas there is evidence for a bilateral organization of the dorsal system, the ventral system might be more lateralized to the right hemisphere, although this assumption is challenged by recent neuroimaging data. Putative intra- and internetwork connections are exemplarily depicted by bidirectional arrows. Interhemispheric connections between homologue areas are not shown. FEF = frontal eye fields; IPS = intraparietal sulcus; VFC = ventral frontal cortex; TPJ = temporoparietal junction; V = visual cortex.
