Non-recurrent deep convolutional neural networks (DCNNs) currently best model core object recognition; a behavior supported by the densely recurrent primate ventral stream, culminating in the inferior temporal (IT) cortex. If recurrence is critical to this behavior, then primates should outperform feedforward-only DCNNs for images that require additional recurrent processing beyond the feedforward IT response. Here we first used behavioral methods to discover hundreds of these “challenge” images. Second, using large-scale electrophysiology, we observed that behaviorally-sufficient object identity solutions emerged ~30ms later in IT for “challenge” images compared to primate performance-matched “control” images. Third, these behaviorally-critical late-phase IT response patterns were poorly predicted by feedforward DCNN activations. Interestingly, very-deep CNNs and shallower recurrent CNNs better predicted these late IT responses, suggesting a functional equivalence between additional nonlinear transformations and recurrence. Beyond arguing that recurrent circuits are critical for rapid object identification, our results provide strong constraints for future recurrent model development.
