Wang and colleagues present a model of the whole cortex (almost).  A gradient of synaptic excitation results in sensory areas show fast responses while cognitive areas show slow integrative activity.  Different temporal hierarchies/dynamics coexist in the same networks.

In general, this fits pretty well with our recent study of actual neural dynamics across the cortex:
