Effective connectivity between the vmPFC and left hippocampus during AM retrieval for different memory ages. (A) Schematic of the 5-s AM retrieval period under consideration. (B) Two proposed models of effective connectivity between the vmPFC and left hippocampus. (C) Free energy as a measure of model fit indicated a stronger influence of the vmPFC on left hippocampal activity during AM retrieval (less negative = more free energy). (D) Connectivity strength for all memory ages (green) and the baseline counting condition (grey). Means and SEM are displayed. For all memory ages, the most likely best fitting model was the vmPFC exerting influence over the left hippocampus. AM = Autobiographical memory, BL = baseline counting, vmPFC = ventromedial prefrontal cortex, HPC = hippocampus, M = months, Y = years. * = P < 0.05, ** = P < 0.01.
