Abstract:
The temporal lobe regions involved in memory retrieval were
examined using functional magnetic resonance imaging (fMRI). During
an associative recognition test, participants made memory judgments
about the study color of previously presented drawings of objects,
and during item recognition tests they made old/new judgments about
previously studied objects or new objects. Associative recognition
compared to old item recognition led to activations in bilateral
hippocampal and parahippocampal regions, as well as in the left
middle occipital gyrus. Old item recognition compared to new item
recognition led to activation in the left middle occipital gyrus
and the left middle temporal gyrus, and relative deactivations in
bilateral hippocampal regions. The results indicate that partially
distinct temporal lobe regions are involved during recognition
memory for item and associative information.
