Diagram of PFC regions and Behavioral Paradigm. a The monkey prefrontal cortex was divided into regions as indicated. Insets represent average delay period firing rate (and sem) for each area, before (hatched bars) and after training (solid bars). b Sequence of events during the passive viewing paradigm. Monkeys were required to fixate a point and a stimulus was shown. After a delay period, a second stimulus was shown either matching the first in location or appearing at a different location. Another delay period followed, after which the monkeys were rewarded for maintaining fixation throughout the entire trial. c The spatial match/nonmatch working memory task. An additional display with two targets was displayed and the monkey now had to saccade to the green square/H if the two stimuli matched or the blue square/diamond if the two stimuli did not match. d Possible locations of the cue and sample stimuli
