Shape-coding in IT cells generalizes over contrast and mirror reversal, but not figure-ground reversal
Abstract
We assessed how the visual shape preferences of neurons in the inferior temporal cortex of awake, behaving monkeys generalized across three different stimulus transformations. Stimulus-preferences of particular cells among different polygon displays were correlated across reversed contrast polarity or mirror reversal, but not across figure-ground reversal. This corresponds with psychological findings on human shape judgments. Our results imply that neurons in inferior temporal cortex respond to components of visual shape derived only after figure-ground assignment of contours, not to the contours themselves.
