Contribution of individual features to repetition suppression in macaque inferotemporal cortex.

ABSTRACT: When an image is presented twice in succession, neurons in area TE of macaque inferotemporal cortex exhibit repetition suppression, responding less strongly to the second presentation than to the first. Suppression is known to occur if the adapter and the test image are subtly different from each other. However, it is not known whether cross suppression occurs between images that are radically different from each other but that share a subset of features. To explore this issue, we measured repetition suppression using colored shapes. On interleaved trials, the test image might be identical to the adapter, might share its shape or color alone, or might differ from it totally. At the level of the neuronal population as a whole, suppression was especially deep when adapter and test were ident
