Distance-related adaptation in the human brain. A, Colored voxels exhibit fMRI response that scales linearly with real-world distances between landmarks shown on successive trials. Distance-related adaptation was observed in the left inferior insula (ins), left aSTS, left anterior hippocampus (hipp), and right pITS. B, fMRI response (mean ± SEM percentage signal change) in the anatomically defined left anterior hippocampus plotted as a function of the real-world distance between successively presented landmarks. C, The same plot for subjective distance. fMRI response in the left anterior hippocampus to repeated-landmark (0-distance) trials was 0.016, which was not significantly different from zero (t = 0.23, p = 0.41).
