    "title": "A Spiking Neural Model of the n-Back Task",
    "subtitle": null,
    "abstract": "We present a computational model performing the n-back task.\nThis task requires a number of cognitive processes including\nrapid binding, updating, and retrieval of items in working\nmemory. The model is implemented in spiking leakyintegrate-\nand-fire neurons with physiologically constrained parameters,\nand anatomically constrained organization. The\nmethods of the Semantic Pointer Architecture (SPA) are used\nto construct the model. Accuracies and reaction times produced\nby the model are shown to match human data. Namely,\ncharacteristic decline in accuracy and response speed with increase\nof n is reproduced. Furthermore, the model provides\nevidence, contrary to some past proposals, that an active removal\nprocess of items in working memory is not necessary\nfor an accurate performance on the n-back task",
