“…Area 18, however, shows more dorsal stream specificity in that the majority of neurons are highly direction selective (Hubel and Wiesel, 1965;Dreher and Cottee, 1975), signifying a clear contribution to motion processing (see more below). However, area 18 is connected not only to higher order areas in the lateral suprasylvian sulcus such as PMLS and PLLS, but also to area 21a (Symonds and Rosenquist, 1984a;Sherk, 1986;Grant and Shipp, 1991;Pospichal et al, 1996;Stewart et al, 2000). It has been suggested that PMLS and 21a are part of the dorsal and ventral streams, respectively, because they are relatively more involved in motion (PMLS) or form (21a) processing (Dreher et al, 1996a,b;Wang and Dreher, 1996;Wang et al, 2007;Villeneuve et al, 2009).…”
