fMRI scanner task, trial coding and example group ROIs. a On each scan trial, the participant viewed the global landmark towards which they were travelling, a boundary and a cue object (pole with ball). The participant then completed a forced-choice decision in which they were presented with the three other global landmarks (i.e., those not seen during the passive movement) and were required to select the landmark located in the direction of the goal object (correct answer here indicated by “Allo Goal Dir”). b Schematic of the 24 passive paths used in the scan task. Each path was repeated four times resulting in 96 trials per run. c Each trial comprised 2 s of passive movement, four seconds in which the visual input was removed (i.e., the portion of the trial used for the fMRI analysis) and 2 s to make the cue object direction decision. Trials were then coded according to either the allocentric boundary direction or the allocentric goal direction. d All analyses were carried out in the participant’s native EPI space using manually segmented masks of the EC and subiculum; the group averaged ROIs are presented here for display purposes only
