      abstract     = {Advances in ultra-high field 7 Tesla functional magnetic
                      resonance imaging (7 T fMRI) have provided unprecedented
                      opportunities to gain insights into the neural underpinnings
                      supporting human memory. The hippocampus, a heterogeneous
                      brain structure comprising several subfields, plays a
                      central role during vivid re-experiencing of
                      autobiographical memories (AM). However, due to technical
                      limitations, how hippocampal subfields differentially
                      support AM, whether this contribution is specific to one
                      portion along the hippocampal long-axis, and how subfields
                      are functionally connected with other brain regions
                      typically associated with AM retrieval remains elusive.
                      Here, we leveraged technical advances of parallel imaging
                      and employed a submillimeter Echo Planar Imaging sequence
                      over the whole brain while participants re-experienced
                      vivid, detail-rich AM. We found that all hippocampal
                      subfields along the long-axis were engaged during AM
                      retrieval. Nonetheless, only the pre/parasubiculum within
                      the anterior body of the hippocampus contributed over and
                      above to AM retrieval. Moreover, whole-brain functional
                      connectivity analyses of the same data revealed that this
                      part of the hippocampus was the only one that was strongly
                      connected to other brain regions typically associated with
                      AM, such as the ventromedial prefrontal cortex (vmPFC) and
                      medial/lateral parietal regions. In the context of the
                      broader literature, our results support recent proposals
                      that the anterior body of the pre/parasubiculum may play an
                      important role in scene-based cognition, such as its
                      engagement during the re-experiencing of personal past
                      events.},
