Brain Structure Comparisons between Healthy American and Chinese Singaporean Young and Old Adults

To evaluate if structural brain differences might be important, we conducted a large comparative study in young and old adults from two cultural/racial groups-Chinese Singaporeans and nonAsian Americans (primarily Caucasian). Several important features distinguish the present study: we recruited a good number of psychometrically well-matched, healthy individuals of varying ages at two sites, ensuring differential cultural exposure.
