“…Although some studies report underrecruitment of the neural regions which are activated in young adults (Logan, Sanders, Snyder, Morris, & Buckner, 2002), others find that older adults recruit new regions which are not typically activated in the young (e.g., Morcom, Good, Frackowiak, & Rugg, 2003;Cabeza, Anderson, Locantore, & McIntosh, 2002). Importantly, differences in functional response are also found when behavioral performance is equivalent between age groups (Morcom, Li, & Rugg, 2007;Langenecker & Nielson, 2003) or when age-related performance differences are methodologically controlled (Morcom et al, 2003), demonstrating that fMRI studies may reveal differences in the nature of older adultsʼ responses, which are not evident from behavioral measures alone.…”
