Object-based visual working memory depends critically on the fronto-temporal cortical network. Exploring the interactions within this network is central to understanding the neural mechanisms of goal directed recall in memory. A delayed color recall task, where colors were associated to achromatic images of scenes and geometric drawings, was used to explore interactions of the temporal and prefrontal cortex by way of high-density electrocorticography (ECoG) in two macaque monkeys. Regions of similar functionality were localized by clustering the time-varying signal of the electrodes in the ECoG arrays over the prefrontal and temporal cortices.
