evidence revealed that participants looked longer at the correct stimulus, and this was related to increases in hippocampal activity. Therefore, the hippocampus may play a role in the recovery of relational information, but it requires concomitant activation with the prefrontal cortex for conscious recollection.

Studies with amnesics do not seem to support the single-process notion. A number of reports feature patients with selective damage to the hippocampus who are impaired only in recollection but not
