摘要：
The cortical network of the prefrontal cortex (PFC) and the posterior parietal cortex (PPC) has been suggested to play central roles in visuospatial working memory processing and attention. However, how these areas contribute to such processes remains obscure. To investigate this, I here propose a layered network model of the PFC and the PPC with feedforward/feedback-type corticocortical connections. Computer simulation with this model shows that the feedback and feedforward connections critically control the time course of the neuronal activity of the PFC and the PPC.
