Landmark discrimination in scene-selective regions and EVC. Left, ROI used in the MVPA analysis (A–D). Colors indicate the number of subjects for which each voxel is included in the ROI. Right, Landmark discrimination, defined as greater similarity for fMRI activation patterns corresponding to the same landmark than for fMRI activation patterns corresponding to different landmarks. Every region could discriminate landmark exteriors from other exteriors, and interiors from other interiors, in all three experiments. In PPA, cross-decoding between interiors and exteriors was significant in subjects familiar with the campus (Experiments 1 and 3), but not in subjects unfamiliar with the campus (Experiment 2). Cross-decoding in RSC was significant in subjects familiar with the campus (Experiment 1) and also subjects unfamiliar with the campus (Experiment 2) but was abolished by an interfering memory task (Experiment 3). OPA could cross-decode in all three experiments regardless of familiarity or mnemonic demands, whereas EVC could never reliably cross-decode.
