The Parahippocampal Cortex Mediates Contextual Associative Memory: Evidence from an fMRI Study

Figure 3

Main-effect analysis. (a) Bilateral PHC activation maps for the main effect of contextual associative memory [(CO + CS) versus (NO + NS)]. (b) The time course of the percent changes in a peak voxel in the left PHC (MNI: −28/−30/−24, ) over the period of the scan. (c) The time course of the percent changes in a peak voxel in the right PHC (MNI: 32/−32/−18, ) over the period of the scan. The percent signal change was calculated individually for each subject using that subject’s fixation activation as baseline and then averaging across subjects (black dot indicates fixation epochs). COs: contextual objects; NOs: noncontextual objects; CSs: contextual shapes; NSs: noncontextual shapes; L: left hemisphere; R: right hemisphere.
