Two visual areas located in the middle suprasylvian gyrus (cytoarchitectonic field 7) of the cat's cortex

Topographic organisation of extrastriate areas in the flying fox: Implications for the evolution of mammalian visual cortex

“…Because of the uncertainty regarding the exact branching of flying foxes, tree shrews, and primates (see, e.g., Martin, 1990), this part of the tree is outlined by dashed lines. The references on which the schematics are based are as follows: northern quoll: squirrel: Kaas et al, 1989(modified according to Sereno et al, 1991Paolini and Sereno, 1998); rat: Montero, 1993;cat: Payne, 1993 (subdivisions of area 7 according to Pigarev and Rodionova, 1998); tree shrew: Sesma et al, 1984;bushbaby: Krubitzer and Kaas, 1990;Rosa et al, 1997a;marmoset: Rosa and Schmid, 1995;Rosa et al, 1997b;Rosa and Elston, 1998. The designations DL, DLc, and VP in the schematics of primate cortex indicate subdivisions of cortex recognised by earlier studies; however, a uniform colour is used to indicate that, as argued elsewhere (Rosa, 1997), these are likely to be parts of a single area that borders V2 in ventral and lateral extrastriate cortex that is the likely homologue of cat area V3.…”

“…12). Payne (1993) and, more recently, Pigarev and Rodionova (1998) have proposed that the areas between V3 and MT/LS are actually homologous in cats and primates. However, because these additional areas are not present in either flying foxes or tree shrews, which are considered by different groups as representatives of the primates' sister group (see, e.g., Pettigrew, 1986;Jain et al, 1994), it is possible that carnivores and primates have independently developed additional areas in this region.…”

Visual response characteristics of neuronal clusters in the caudate nucleus of behaving cats

“…Our model apparently yields at least two hours recording time per day throughout several years from the same animal, with continuous eye movement control and stable head position. The head was restrained in some earlier used feline models, too (Hubel, 1959;Huxlin and Pasternak, 2004;Pigarev and Levichkina, 2011;Pigarev and Rodionova, 1998;Yin, 1998, 2002;Tollin et al, 2005), and some form of eye movement control was also present in other studies (e.g. ), but to our knowledge we have been the first to utilize this whole range of methods at the same time.…”

“…Stryker and Blakemore (1972) took a step further, fixated the body and head of the cat with a canvas bag on a platform, and the eye movements were put under video surveillance. For some time, the scleral magnetic search coils developed for primates were utilized (Fuchs and Robinson, 1966;Robinson, 1963), but later they were adapted to cats (Huxlin and Pasternak, 2004;Pigarev and Levichkina, 2011;Pigarev and Rodionova, 1998;Yin, 1998, 2002;Tollin et al, 2005).…”

“…In visual electrophysiology, only a few research groups are known that have performed visual experiments on eyemovement controlled, behaving cats. Pigarev and his colleagues investigated the visual cortical areas (Pigarev and Levichkina, 2011;Pigarev and Rodionova, 1998 (2004) investigated the training-induced recovery of visual motion perception after extrastriate cortical damage in adult cats. In each case, the head of the animal was fixed and its body was put either in a box or on a trolley, which could move along a 3-m long railway or in a canvas bag on a platform.…”
