A BOLD-fMRI run refers to the acquisition of fMRI data on one single task. At least, there were two BOLD runs, corresponding to PA- and AP- phase-encoding directions for each task during a session. The 2D Spin-Echo PA/AP maps were always acquired before the runs dedicated to the collection of BOLD-fMRI data and repeated afterwards.
*Full descriptions of task siglas are provided in Section “Experimental Paradigms”.
**For BOLD fMRI sequences, the durations presented here account only for the period of the actual acquisition. The full duration of each run also included ∼45 s of calibration scans, always performed at their beginning.
†Mental Time Travel task featuring “West-East island” stimuli.
‡Mental Time Travel task featuring “South-North island” stimuli.
§The run “Self 4” relates to a longer version of the others runs of the same task. Thus, “Self 4” contains four pairs of Encoding + Recognition phases, whereas the remaining runs contain only three pairs.
