However, there is also evident divergence in the pattern of OFC and ACC connections when estimates are compared of the connectivity with parts of the temporal lobe which connect to prefrontal cortex via the uncinate fascicle and extreme capsule in monkeys (Petrides and Pandya, 2002; Ungerleider, Gaffan and Pelak, 1989). The OFC showed a high degree of interconnection with these areas, particularly in the lateral region that was observed to be activated in the FIXED+MONITOR condition, but only sparse connections with the ACCs were recorded (Figure 5a, b). These results were observed in both humans and monkeys, suggesting that these areas have correspondence between species. This means, of the two regions, only the OFC is in a position to receive highly processed sensory information, which may help account for its involvement in externally-guided actions and in altering stimulus-reward associations.
