      abstract     = {We present neuroanatomical correlates of encoding and
                      retrieval in an episodic memory task using visually
                      presented highly imaginable word-pair associates. A total of
                      13 right-handed normal male volunteers took part in the
                      study. Each subject underwent six 15O-butanol PET scans. On
                      each of the six trials the memory task began 30 s before the
                      injection of a bolus of 15O-butanol. The subjects had to
                      learn and retrieve 12 word pairs (highly imaginable words,
                      not semantically related, hard associations). The
                      presentation of nonsense words served as a reference
                      condition. Recall accuracy after 2–4 presentations was
                      $66.1\%921.1$ correct during the PET measurement so that
                      scanning during the retrieval of word pair associates was
                      appropriate to capture the brain activity associated with
                      retrieval. The results obtained support the hypothesis of
                      the presence of an asymmetric network consisting of
                      distributed brain structures subserving associative memory.
                      We show left dorsolateral prefrontal activation during the
                      encoding of visually presented word pair associates, whereas
                      retrieval led to bilateral frontal activation. Furthermore,
                      the importance of the precuneus in the retrieval of highly
                      imaginable word-pair associates using visual imagery as a
                      mnemonic strategy is demonstrated.},
