Dynamic Hierarchical Firing within a Single Layered Network: A Model of the PFC

We propose a single layered neural network model of the prefrontal cortex which shows dynamic hierarchical firing, that is to say, sensory input is gradually translated into motor output along time. Such hierarchical firing is actually observed in the monkey prefrontal cortex (PFC), but its development remains an open question. The numerical analysis of the model indicated that the feedback signals from the premotor cortex may play an important role in the development of hierarchical firing
