Abstract:It is established that perceptual learning enhances the signal-to-noise ratios of sensory processing. However, the specific mechanisms behind this improvement remain enigmatic. Here, we systematically investigated these mechanisms by analyzing population activity changes in deep convolutional neural networks (DCNNs), humans, and macaques. We first trained DCNNs on orientation and motion direction discrimination tasks. Our models successfully replicated the behavioral signature of enhanced signal-to-noise ratio… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
