The cat’s postero-temporal ventral (PTV) cortex encompasses cytoarchitectonic areas 20a and 20b (Tusa and Palmer, 1980). PTV constitutes a distinct part of pattern/form information processing stream (Campbell, 1978; Lomber et al., 1996a, b) and is the presumed homolog of primate infero-temporal cortex (Payne, 1993). Although PTV and primary visual cortices are interconnected only indirectly (Figure 1B, Rosenquist, 1985; Dreher, 1986; Dreher et al., 1996; Burke et al., 1998; Batardiere et al., 1998), reversible inactivation of PTV affects the responses and a number of receptive field (RF) characteristics, of a substantial proportion of neurons in the part of V1 corresponding visuotopically to PTV (Bardy et al., 2006, 2009; Huang et al., 2007).
