Figure 4. Brain regions more engaged by permanent than transient landmarks by the end of learning.
(A) Shows activations in retrosplenial cortex (RSC) and posterior parieto-occipital sulcus (POS) at the default threshold of p < 0.05 (FWE). The colour bar indicates Z-score associated with each voxel. (B) Shows a plot of mean blood oxygenation level-dependent (BOLD) responses (±1 SEM) within the RSC cluster (circled in green). In the first two quarters of scanning, responses to permanent (blue) and transient (red) landmarks did not differ, but as subjects learned landmark permanence, BOLD responses increased for permanent landmarks with a corresponding decrease for transient landmarks.
