Sparse coding in the primate cortex
... especially in infero-temporal cortex (IT). Cells’ preferences in IT are often difficult to account for by reference to simple stimulus features, such as orientation, motion, position, or color, and they appear to lie in the domain of shape (Gross, Rocha-Miranda, and Bender, 1972; Perrett et al., 198 ...
