Anatomical location, sensory properties and corticocortical connections of the SPL areas. A Posterior view of macaque occipital and parietal lobes. The right hemisphere (posterolateral view) has been partially dissected at the level of the fundus of intraparietal, parieto-occipital, and lunate sulci to show the hidden cortex of SPL. The medial surface of the left hemisphere is also visible. Continuous lines delimit the different SPL areas (in color) described in this work. B Incidence of visual and somatosensory cells in areas V6, V6A (V6Av and V6Ad), PEc, and PE. Data are obtained by the following studies (Galletti et al. 1999a; Gamberini et al. 2011, 2018; De Vitis et al. 2019). C Summary of cortical connections of areas V6, V6A (V6Av and V6Ad), PEc and PE modified from the following studies (Galletti et al. 2001; Gamberini et al. 2009; Bakola et al. 2010, 2013; Passarelli et al. 2011). The boxes representing different areas are organized approximately in a caudal to rostral sequence, from the bottom part of the figure to the top. The proportion of neurons forming each connection is indicated by the thickness of the bars linking different areas. cal calcarine fissure, cin cingulate sulcus, V2, V3, V3A, V4/DP, V4T, MT, MST, V6Av, V6Ad, PEci, PGm, 31, 23, 24, PE, PEip, S1, PIVC, OPT, PGop, PG, PFop, Ri, dMIP, VIP, LIP, AIP, 2, 3b, 3a, 1, 46, F1, F3, F7 areas V2, V3, V3A, V4/DP, V4T, MT, MST, V6Av, V6Ad, PEci, PGm, 31, 23, 24, PE, PEip, S1, PIVC, OPT, PGop, PG, PFop, Ri, dMIP, VIP, LIP, AIP, 2, 3b, 3a, 1, 46, F1, F3, F7.
