The relationship between limbic activity and emotional reactions to and enhanced memory for emotional material has been established for nonverbal stimuli. However, it is unknown whether this relationship holds for other stimuli such as words and whether it is modulated by individual differences in personality variables (e.g., Canli et al., 1999). We examined emotional memory and emotional reactions to verbal and nonverbal (photograph) stimuli using functional magnetic resonance imaging. The goals were to examine the neural correlates of emotional reactions to pleasant, unpleasant, and neutral verbal material, compare these correlates to the correlates of reactions to nonverbal material, and identify brain areas whose activity is correlated with memory for each type of emotional material. In addition, personality trait data were assessed to examine the possible modulatory role of personality characteristics. Functional imaging was conducted with a Philips 1.5 T ACS/NT scanner using gradient-recalled echo-planar imaging. Initial data (N=6) found that the areas activated by verbal and nonverbal emotional stimuli substantially overlapped for the negative-neutral contrast (amygdala, bilat. occipital) and the positive-neutral contrast (orbitofrontal cortex, ant. cingulate, basal ganglia, precuneus), although there were also material-specific areas of activation. Correlations with memory and personality variables were also examined. In summary, these data suggest that the neural response to verbal and nonverbal emotional stimuli overlap substantially.
