Task description and reinstatement analysis. a Electrode placement. One hippocampal and one lateral temporal cortex electrode from the same hemisphere was selected in each patient. Figure shows the selected contacts from all patients in MNI space. b Experimental task: overview. Participants navigated a virtual maze (top left) and visited several rooms (top right) where visual item were presented (bottom left). During retrieval, participants conducted a recognition memory task (bottom right). Items were either presented in the same room (congruent condition) or in a different room (incongruent condition). c Experimental task: individual trials. Timeline of one example trial during the encoding and retrieval blocks. d Representational similarity analysis. Time-frequency patterns were extracted from individual electrodes (44 frequencies between 1–100 Hz), in time windows of 500 ms, overlapping by 400 ms. Reinstatement corresponded to Spearman’s correlations for all encoding-retrieval time pairs
