Figure 1.

The ADRA2B genotype affects memory formation in the amygdala and inferior frontal gyrus. Coronal slices showing amygdala (upper row) and inferior frontal gyrus (lower row) effects (i.e., subsequent hits—subsequent misses) at the peak of the interaction. Columns show activations for nondeletion carriers, deletion carriers, the interaction between genotype, and memory, as well as the parameter estimates for the peak voxel of the activated cluster for illustration of the interaction (subsequent hits—subsequent misses; mean ± SEM). In all images, the left side corresponds to the left hemisphere, and the figures are displayed at P < 0.005, uncorrected for illustration purposes.
