(A) We extracted beta estimates from the hippocampal ROI, based on coordinates identified by Bergouignan et al. (2014); X = −27, Y = −31, Z = −11), corresponding to the univariate contrast comparing memory retrieval, regardless of condition, to the baseline task. Beta estimates were significantly below zero (P = 0.001), indicating deactivation of the left posterior hippocampus during memory retrieval. The dotted line indicates a null effect (i.e. no effect of retrieval on activity in the hippocampal mask). (B) Memory reinstatement (i.e. encoding-retrieval pattern similarity) was stronger for memories encoded with strong body ownership (synchronous versus asynchronous condition) and increasing levels of vividness in the left posterior hippocampal ROI (x-axis: hippocampus), P = 0.03, and in the larger set of regions that decoded strong versus weak body ownership during encoding, P = 0.01 (x-axis: encoding mask). Pearson correlations, between the neural data extracted from each ROI and the individual contrast matrices specifying stronger reinstatement for memories encoded with strong body ownership and retrieved with high vividness (see Fig. 4B), are significantly greater than zero. The dotted line indicates a null effect (i.e. no encoding-retrieval pattern similarity).
