BRAIN AND FALSE MEMORY
Figure S1. Hippocampus, parahippocampal gyrus, and fusiform gyrus. Models are displayed on one randomly chosen male subject in the coronal view of the brain (the same subject as presented in Figure 2A). Left and right hippocampal 3D surface models (yellow) created with Slicer derived from the Freesurfer subcortical segmentations. Left and right fusiform gyri 3D surface models (light cyan) and left and right parahippocampal gyri 3D surface models (green) created with Slicer derived from the Freesurfer parcellation results.
