A hypothesis-based functional MRI (fMRI) study of hippocampal activity during memory formation found that the hippocampus organizes discrete, disparate events into a coherent narrative, according to researchers at the University of California, Davis, in a study published online September 29, 2021, in Current Biology.
Lead author Brendan Cohn-Sheehy, et al., wrote that “even though life’s events occur at disparate times, the hippocampus can form memories that integrate events into a larger, coherent narrative. By bridging the divide between distant events, the hippocampus may support a narrative-level architecture for episodic memory.”
The team says that their findings offer a fascinating look into how the brain integrates information. “[Our] findings suggest that, rather than simply integrating memories of overlapping experiences, the hippocampus supports the construction of narratives that integrate distant events in memory,” they concluded.
