Regulating personal emotion becomes a higher priority with age and older adults report having better control over their emotions than younger adults. In this study, we used functional MRI to investigate whether the increased importance of emotion regulation with age is associated with changes in processing of emotional material. Functional magnetic resonance imaging (fMRI) was performed on a GE 3T Signa scanner. Functional whole-brain images were acquired using a gradient echo T2*-weighted spiral scan (TR=1 s; TE=30ms; flip angle=60; FOV=24 cm). Sixteen younger (20-30 years old) and 16 older (74-90 years old) adults were shown positive, negative, and neutral photographs. A recognition test was given immediately after scanning and a free recall test was administered two days later. In comparison to younger adults, older adults remembered disproportionately fewer negative photographs than positive or neutral photographs in both the recognition and free recall tests. Younger adults exhibited more activation in response to negative, relative to positive, pictures in posterior visual and right frontal regions. In contrast, older adults exhibited more activation in response to positive, relative to negative, pictures in left frontal regions. These results suggest that there are age-related changes in both the way emotional material is attended to and the way it is remembered later.
