Matt Chafee and colleagues used multiple-electrode recording in the prefrontal and parietal cortices to examine the temporal dynamics of their neural activity during a categorization task.   They decoded category signals from patterns of simultaneously recorded in small bins and asked whether the resulting  information  time series in one area could predict the other.  This showed that  “executive” top-down signals flow from the prefrontal to parietal cortex.
