The division of cortical visual processing into distinct dorsal and ventral streams is a key framework that has guided visual neuroscience. The characterization of the ventral stream as a 'What' pathway is relatively uncontroversial, but the nature of dorsal stream processing is less clear. Originally proposed as mediating spatial perception ('Where'), more recent accounts suggest it primarily serves non-conscious visually guided action ('How'). Here, we identify three pathways emerging from the dorsal stream that consist of projections to the prefrontal and premotor cortices, and a major projection to the medial temporal lobe that courses both directly and indirectly through the posterior cingulate and retrosplenial cortices. These three pathways support both conscious and non-conscious visuospatial processing, including spatial working memory, visually guided action and navigation, respectively.

Architectural design and the brain: effects of ceiling height and perceived enclosure on beauty judgments and approach-avoidance decisions (2015, methodology): “Third, it is also possible that much like high ceilings, open spaces facilitate visuospatial exploration, in the process activating parietal and frontal regions in the dorsal stream (Mishkin et al., 1983; Ungerleider & Mishkin, 1982; see also Kravitz et al., 2011).”
