AGE by GENE interactions in the “novel versus familiar” contrast of the encoding task. (a) Regions showing significant interaction between AGE and GENE factors ( , corrected for multiple comparisons) with plots of percentage signal change in brain regions showing group-related differences where ε4 (orange) defines ε4-carriers and NC (green) defines noncarriers. (b) ROIs for the left and right hippocampi overlaid on a structural image (left) with associated plot of average hippocampal percentage signal change showing significant age-by-gene interaction (left hippocampus: , right hippocampus: ) (adapted with permission from [33]).
