Neuroanatomical correlates of selected executive functions in middle-aged and older adults: a prospective MRI study.

Neuroanatomical substrates of age-related differences in working memory and perseverative behavior were examined in a sample of healthy adults (50-81 years old). The participants, who were screened for history of neurological, psychiatric, and medical conditions known to be linked to poor cognitive performance, underwent magnetic resonance imaging (MRI) and were administered tests of working memory and perseveration.
