The ability to form associations between a multitude of events is the hallmark episodic memory. Computational models have espoused importance hippocampus as convergence zone, binding different aspects an episode into coherent representation, by integrating information from multiple brain regions. However, evidence for this long-held hypothesis limited, since previous work has largely focused on representational and network properties in isolation. Here we identify mnemonic using combination multivariate pattern graph-theoretical analyses functional magnetic resonance imaging data humans performing associative memory task. We observe overlap conjunctive coding hub-like attributes hippocampus. These results provide hippocampus, underlying integration distributed representations.
