Behavioral and EP data. A, RTs and ERs are plotted separately for past (blue), now (red), and future (green) self-locations in time. Error bars indicate intersubject SEM. Note the significantly higher RTs and ERs for past and future with respect to the now. In addition, in all self-locations (past, now, future) RTs and ERs were higher for the relative past (left bars, darker colors) than the relative future (right bars, lighter colors). B, Segments of stable map topography in the three temporal self-locations under the global field power curve from 0 to 800 ms. EP segment 11 (future map) was found at ∼300–400 ms and was significantly longer for future self-location (green) than for the past (blue) and now (red). EP segment 14 (MTT map) was found at ∼500–600 ms and was significantly longer for past and future self-locations than for the now. C, Map topography and duration of MTT map (right) and future map (left) for the three experimental self-locations for all participants. Note that duration of the MTT map parallels the behavioral results. In all temporal self-locations MTT map duration was longer for the relative past (left bars, darker colors) than for the relative future (right bars, lighter colors). D, Generators of MTT map were localized to the right temporoparietal, occipitotemporal, and left anteromedial temporal cortices.
