First paragraph (this article has no abstract)

In contrast to the classical theory of segregated cortical representation of information regarding the identity ("what") and location ("where") of a visual object, recent experimental results indicate that neurons in the primate prefrontal cortex convey combined information about both [1]. Moreover, this information was found to be maintained after stimulus removal, suggesting that these neurons contribute to working memory. To date, the mechanisms that underlie this integrated representation are unknown. In this study, we propose a model of a cortical network with biologically realistic properties that demonstrates a combined representation of stimulus identity and location.
