“…Each of these thalamic cell groups are visually responsive (Hicks et al, 1984;Hutchins and Updyke, 1989), and all receive ascending tectothalamic projections (Graybiel, 1972;Graham, 1977;Huerta and Harting, 1984;Takada et al, 1985;Hicks et al, 1986). The cortex occupied by the insular visual area has been reported to project to areas 6a, 6a␣, 6a␥, and PFdl (Cavada and Reinoso-Suá rez, 1985;Nakai et al, 1987;Olson and Jeffers, 1987;Ghosh, 1997d), less heavily to areas 6if.fu, PFdm, PFr, PFv, 32, and 24 (Cavada and Reinoso-Suá rez, 1985;Guldin et al, 1986;Musil and Olson, 1988a,b;Ghosh, 1997d), and sparsely to areas 4␥ and 4␦ (Ghosh, 1997c).…”
