The present study aims to assess the age-related neural
changes particularly concerning the role memory plays
during emotional sentence processing, by employing
functional magnetic resonance imaging (fMRI). Although
emotional valence did not explicitly moderate behavior
within sentence recognition task both in young and
elderly groups, neural activity during the task showed
particular interaction effects between emotional valence
and age group.@ Among the enhanced regions for
recognizing positive emotional sentences, the insula is
known to be involved in emotional awareness. Our results
suggest that the insula might reflect the elderliesf
greater awareness to positive emotional sentences.
